Amazon Alexa Smart Home Skill

Alexa is an intelligent personal assistant developed by Amazon and designed to run on smart speakers and devices such as the Amazon Echo and Dot.

This certified Amazon Smart Home Skill allows users to control their openHAB powered smart home with natural voice commands. Lights, locks, thermostats, AV devices, sensors and many other device types can be controlled through a user's Alexa powered device like the Echo or Dot.

This page describes how to use the openHAB Alexa Smart Home Skill. The skill connects your openHAB setup through the myopenHAB.org cloud service to Amazon Alexa.

Setup

NEW Alexa Version 3 API syntax (v3)
- Version 3 of the Alex Skill API introduces a more rich and complex set of features that required a change in how items are configured by using the new metadata feature introduced in openaHAB 2.3
- Version 2 tags are still supported and are converted internally to v3 meta data
- Supported item & group v3 meta data
- Automatically determine number precision and unit based on item state presentation and unit of measurement.
- Decoupling between item receiving command and item state via an item sensor
- Improved Alexa response state accuracy
- Support for building block APIs and semantic extensions latest features

Requirements

openHAB Cloud Connector configured using myopenHAB.org
Amazon account
Amazon Echo, Amazon Echo Dot or compatible Alexa device

Recommendations

Item Labels

Matching of voice commands to items happens based on the item label (e.g. "Kitchen Light"). If it is not specified, the item will be ignored. It is therefore advisable, to choose labels that can be used to form natural commands. As an example, compare "Alexa, turn on the Kitchen Light" vs. "Alexa, turn on the Ground Floor LEDs Kitchen".

Regional Settings

In order for the skill to determine your default language and measurement system to use, during the discovery process, for some of the controllers supporting friendly language-based names and unit of measurement, it is important to set your server regional settings including the language, country/region and measurement system properties. These can either be accomplished by using Paper UI (Configuration > System > Regional Settings) or setting the language, region and measurementSystem properties for org.eclipse.smarthome.i18n or org.eclipse.smarthome.core.i18nprovider service (depending on release version) in $OPENHAB_CONF/services/runtime.cfg. If these settings aren't defined, the skill will either use the item level configuration, if available, to determine these properties, or fallback to en language and SI measurement system, as default values.

Concept

The Alexa skill API uses the concept of "endpoints". Endpoints are addressable entities that expose functionality in the form of capability interfaces. An example endpoint may be a light switch, which has a single capability called power state (ON/OFF). A more complex endpoint may be a thermostat which has many capabilities to control and report temperature, setpoints, modes, etc...

Single Endpoint

Single items in openHAB can be mapped to single endpoint in Alex through the use of the Alexa metadata.

An simple example of this is a light switch. In openHAB a light switch is defined as a "Switch" item and responds to ON or OFF commands.

Switch LightSwitch "Light Switch"

In the Alexa skill a light switch endpoint implements the "PowerController" interface and exposes a "powerState" property. To map our openHAB switch to a PowerController endpoint we use a Alexa metadata:

Switch LightSwitch "Light Switch" {alexa="PowerController.powerState"}

Setting this on a single item will create an Alexa endpoint with the spoken addressable name "Light Switch" and map the powerState property to our item. You can ask Alexa to turn "Light Switch" on or off.

This can also be written using metadata labels, which is a shorthand version of the full Alexa namespace:

Switch LightSwitch "Light Switch" {alexa="Switchable"}

A slightly more complex example would be a Light Dimmer. In openHAB a dimmer object responds to both percentage and ON / OFF commands. In Alexa this is two different interfaces. To support both types of commands, we need to add both to the item metadata:

Dimmer LightSwitch "Light Switch" {alexa="PowerController.powerState,BrightnessController.brightness"}

You can ask Alexa to "Turn Light Switch .." on or off as well as "Set Light Switch to .." a certain percentage.

Using metadata labels this would look like:

Dimmer LightSwitch "Light Switch" {alexa="Lighting"}

NOTE: the Alexa skill has 3 different percentage interfaces, BrightnessController, PowerLevelController and PercentageController. Your item should only be using one of these that best describes the type of device. So for lights this would be the BrightnessController, for roller shades this would be PercentageController. The skill will not prevent adding more then one, but voice control may suffer for that device.

Group Endpoint

While single mapping items works for many use cases, occasionally multiple openHAB items need to be mapped to a single endpoint in Alexa. When using a group item, keep in mind that there can only be one specific interface capability per group. If you need to have more than one instance of a given capability, you should use the building block APIs controllers.

Below are examples for various use cases, such as a thermostat, a smart bulb, a stereo and a security system.

In openHAB a thermostat is modeled as many different items, typically there are items for setpoints (target, heat, cool), modes, and the current temperature. To map these items to a single endpoint in Alexa, we will add them to a group which also uses "Alexa" metadata. When items are Alexa-enabled, but are also a member of a group Alexa-enabled, they will be added to the group endpoint and not exposed as their own endpoints.

Group  Thermostat    "Bedroom"                                {alexa="Endpoint.Thermostat"}
Number Temperature   "Temperature [%.0f °F]"   (Thermostat)   {alexa="TemperatureSensor.temperature"}
Number CoolSetpoint  "Cool Setpoint [%.0f °F]" (Thermostat)   {alexa="ThermostatController.upperSetpoint"}
Number HeatSetpoint  "Heat Setpoint [%.0f °F]" (Thermostat)   {alexa="ThermostatController.lowerSetpoint"}
Number Mode          "Mode [%s]"               (Thermostat)   {alexa="ThermostatController.thermostatMode"}

The group metadata also describes the category for the endpoint, in this case a "Thermostat". See the section below on supported group metadata and categories for a complete list. In this example a single endpoint is created called "Bedroom", its various interfaces are mapped to different openHAB items. You can ask Alexa "Set the Bedroom thermostat to 72" and the 'HeatSetpoint' will receive the command, if currently in heating mode, likewise you can ask Alexa "What's the temperature of the Bedroom" and Alexa will query the "Temperature" items for its value.

When mapping items, sometime we need to pass additional parameters to Alexa to set things like what scale to use (Fahrenheit) or what values our items expect for certain states (thermostat modes). These parameters can be passed in the metadata properties, if they are omitted, then reasonable defaults are used. In our above example we may wish to use Fahrenheit as our temperature scale, and map the mode strings to numbers. This would look like:

Group  Thermostat    "Thermostat"                             {alexa="Endpoint.Thermostat"}
Number Temperature   "Temperature [%.0f °F]"   (Thermostat)   {alexa="TemperatureSensor.temperature" [scale="Fahrenheit"]}
Number CoolSetpoint  "Cool Setpoint [%.0f °F]" (Thermostat)   {alexa="ThermostatController.upperSetpoint" [scale="Fahrenheit"]}
Number HeatSetpoint  "Heat Setpoint [%.0f °F]" (Thermostat)   {alexa="ThermostatController.lowerSetpoint" [scale="Fahrenheit"]}
Number Mode          "Mode [%s]"               (Thermostat)   {alexa="ThermostatController.thermostatMode" [OFF=0,HEAT=1,COOL=2,AUTO=3]}

For thermostat integration such as Nest or Ecobee, a more complex configuration could involve having three setpoints and additional upper and lower setpoints for eco mode when these are different than the standard ones. Compared to the previous example, the temperature scale here will be based on the item state presentation unit (°F => Fahrenheit) and the thermostat mode will be mapped according to the binding name.

Group  Thermostat      "Thermostat"                                {alexa="Endpoint.Thermostat"}
Number Temperature     "Temperature [%.0f °F]"       (Thermostat)  {alexa="TemperatureSensor.temperature"}
Number TargetSetpoint  "Target Setpoint [%.0f °F]"   (Thermostat)  {alexa="ThermostatController.targetSetpoint"}
Number HighSetpoint    "High Setpoint [%.0f °F]"     (Thermostat)  {alexa="ThermostatController.upperSetpoint"}
Number LowSetpoint     "Low Setpoint [%.0f °F]"      (Thermostat)  {alexa="ThermostatController.lowerSetpoint"}
Number EcoHighSetpoint "High Eco Setpoint [%.0f °F]" (Thermostat)  {alexa="ThermostatController.upperSetpoint#eco"}
Number EcoLowSetpoint  "Low Eco Setpoint [%.0f °F]"  (Thermostat)  {alexa="ThermostatController.lowerSetpoint#eco"}
Number Mode            "Mode [%s]"                   (Thermostat)  {alexa="ThermostatController.thermostatMode" [binding="nest"]}

A smart bulb is another example when it supports shade of colors. Below are two ways to set up a color and a dimmable white bulb with color temperature capability.

Group  Bulb        "Bulb"                {alexa="Endpoint.Light"}
Color  Color       "Color"       (Bulb)  {alexa="BrightnessController.brightness,PowerController.powerState,ColorController.color"}
Dimmer Temperature "Temperature" (Bulb)  {alexa="ColorTemperature.colorTemperatureInKelvin"}

Group  Bulb        "Bulb"                {alexa="Endpoint.Light"}
Dimmer White       "White"       (Bulb)  {alexa="BrightnessController.brightness,PowerController.powerState"}
Dimmer Temperature "Temperature" (Bulb)  {alexa="ColorTemperature.colorTemperatureInKelvin"}

A Stereo is another example of a single endpoint that needs many items to function properly. Power, volume, input, speakers and player controllers are all typical use cases for a stereo that a user may wish to control.

Group Stereo    "Stereo"            {alexa="Endpoint.Speaker"}
Number Volume   "Volume"  (Stereo)  {alexa="Speaker.volume"}
Switch Mute     "Mute"    (Stereo)  {alexa="Speaker.muted"}
Switch Power    "Power"   (Stereo)  {alexa="PowerController.powerState"}
String Input    "Input"   (Stereo)  {alexa="InputController.input" [supportedInputs="HDMI1,TV"]}
String Channel  "Channel" (Stereo)  {alexa="ChannelController.channel"}
Player Player   "Player"  (Stereo)  {alexa="PlaybackController.playback"}
Number Bass     "Bass"    (Stereo)  {alexa="EqualizerController.bands:bass" [range="-10:10"]}
Number Midrange "Mid"     (Stereo)  {alexa="EqualizerController.bands:midrange" [range="-10:10"]}
Number Treble   "Treble"  (Stereo)  {alexa="EqualizerController.bands:treble" [range="-10:10"]}
String Mode     "Mode"    (Stereo)  {alexa="EqualizerController.modes" [supportedModes="MOVIE,MUSIC,TV"]}

A security system is another example including alarm mode and different alarm states.

Group  SecuritySystem      "Security System"                  {alexa="Endpoint.SecurityPanel"}
String AlarmMode           "Alarm Mode"      (SecuritySystem) {alexa="SecurityPanelController.armState" [supportedArmStates="DISARMED,ARMED_STAY,ARMED_AWAY"]}
Switch BurglaryAlarm       "Burglary"        (SecuritySystem) {alexa="SecurityPanelController.burglaryAlarm"}
Switch FireAlarm           "Fire"            (SecuritySystem) {alexa="SecurityPanelController.fireAlarm"}
Switch CarbonMonoxideAlarm "Carbon Monoxide" (SecuritySystem) {alexa="SecurityPanelController.carbonMonoxideAlarm"}
Switch WaterAlarm          "Water"           (SecuritySystem) {alexa="SecurityPanelController.waterAlarm"}

Building Block APIs

For components of a device, which isn't covered by the existing interfaces, that have more than one setting, characterized by a number within a range or just turn on and off, the Mode, Range and Toggle controllers can be used to highly customize how you interact with that device via Alexa. These capabilities can be used like building blocks to model the full feature set of a complex device. With the expansion of these controllers support to other languages, the skill will use your server regional settings if available, falling back to en, to determine your default language setting.

A washer and its settings modeled with multiple mode/toggle interface capabilities.

Group Washer       "Washer"               {alexa="Endpoint.Other"}
String Cycle       "Cycle"       (Washer) {alexa="ModeController.mode" [supportedModes="Normal=Normal:Cottons,Delicate=@Value.Delicate:Knits",friendlyNames="Wash Cycle,Wash Setting",ordered=false]}
Number Temperature "Temperature" (Washer) {alexa="ModeController.mode" [supportedModes="0=Cold:Cool,1=Warm,2=Hot",friendlyNames="Wash Temperature,@Setting.WaterTemperature",ordered=true]}
String Status      "Status"      (Washer) {alexa="ModeController.mode" [supportedModes="Washing,Rinsing,Spinning",friendlyNames="Wash Status",nonControllable=true]}
Switch Power       "Power"       (Washer) {alexa="ToggleController.toggleState" [friendlyNames="@DeviceName.Washer"]}

A fan and its settings modeled with multiple range/toggle interface capabilities.

Group Fan     "Fan"          {alexa="Endpoint.Fan"}
Number Speed  "Speed"  (Fan) {alexa="RangeController.rangeValue" [supportedRange="1:10:1",presets="1=@Value.Minimum:@Value.Low:Lowest,10=@Value.Maximum:@Value.High:Highest",friendlyNames="@Setting.FanSpeed,Speed"]}
Switch Rotate "Rotate" (Fan) {alexa="ToggleController.toggleState" [friendlyNames="@Setting.Oscillate,Rotate"]}
Switch Power  "Power"  (Fan) {alexa="ToggleController.toggleState" [friendlyNames="@DeviceName.Fan"]}

A router and its settings modeled with multiple toggle interface capabilities.

Group Router       "Router"                 {alexa="Endpoint.NetworkHardware"}
Switch 2GGuestWiFi "2G Guest WiFi" (Router) {alexa="ToggleController.toggleState" [friendlyNames="@Setting.2GGuestWiFi"]}
Switch 5GGuestWiFi "5G Guest WiFi" (Router) {alexa="ToggleController.toggleState" [friendlyNames="@Setting.5GGuestWiFi"]}
Switch Power       "Power"         (Router) {alexa="ToggleController.toggleState" [friendlyNames="@DeviceName.Router"]}

Semantic Extensions

Semantic extensions are used to further customize how to interact with a device. This functionality is only supported by the Mode, Range and Toggle controllers. It currently provides "Close", "Open", "Lower" and "Raise" interactions, removing the need for the Alexa routine workaround to control certain devices such as blinds or doors. Each semantic is composed of action and state mappings. The actions are used for interacting with the device and the states for displaying its current semantic state in the Alexa app (Not available as of yet). The supported action and state names are listed in the semantic catalog.

A standard blind with range interface capability (Metadata label: Blind). For example, requesting "Alexa, open the blind", the item state will be set to 100. Likewise, asking "Alexa, lower the blind", the item state will be decreased by 10 from its current state.

Rollershutter Blind "Blind" {alexa="RangeController.rangeValue" [category="INTERIOR_BLIND", friendlyNames="@Setting.Opening", supportedRange="0:100:10", unitOfMeasure="Percent", actionMappings="Close=0,Open=100,Lower=(-10),Raise=(+10)", stateMappings="Closed=0,Open=1:100"]}

A shutter with mode interface capability. For example, requesting "Alexa, open the shutter" or "Alexa, raise the shutter", the item state will be set to Up.

String Shutter "Shutter" {alexa="ModeController.mode" [category="EXTERIOR_BLIND", friendlyNames="@Setting.Opening", supportedModes="Up=@Value.Open,Down=@Value.Close", actionMappings="Close=Down,Open=Up,Lower=Down,Raise=Up", stateMappings="Closed=Down,Open=Up"]}

A door with toggle interface capability (Metadata label: Door). For example, requesting "Alexa, open the door", the item state will be set to ON.

Switch Door "Door" {alexa="ToggleController.toggleState" [category="DOOR", friendlyNames="@Setting.Opening", actionMappings="Close=OFF,Open=ON", stateMappings="Closed=OFF,Open=ON"]}

Item Sensor

Whenever, a device in openHAB uses a separate channel for its status, that item (called "sensor") can be mapped in the actionable item parameters. This feature is design to improve state reporting accuracy by allowing the property state of the sensor item to be reported over the actionable one. It is configured by adding the metadata parameter itemSensor=<itemName>.

It is important to note that sensor items need to be the same type than their parent item, except for LockController capable items. Additionally, since deferred reporting is not supported by the skill as of yet, their state will need to be available right away for the skill to report the device latest status.

Below is an example of a lock device using an item sensor.

Switch LockControl "Lock" {alexa="LockController.lockState" [itemSensor="LockStatus"]}
Contact LockStatus "Status"

Item State

Item states, reported back to Alexa, are formatted based on their item state presentation definition if configured. This means you can control the precision of number values (e.g. %.1f °C will limit reported temperature value to one decimal point).

For items that don't have a state, these can be configured as not retrievable, automatically when the item parameter autoupdate is set as autoupdate=false or by using metadata parameter itemStateRetrievable=false. In that case, Alexa will not retrieve the given item state, and when a command is issued against that item, the requested state will be returned back without checking the current state in openHAB. If using this feature in a group endpoint, keep in mind that all associated items will need to be configured to either report or not report a state, otherwise the Alexa integration for that endpoint will be broken.

Item Unit of Measurement

With the introduction of the unit of measurement concept, the item unit can be automatically determined for thermostat and temperature using that feature, removing the need of having to set the metadata scale parameter for each of the relevant items or groups.

Below are two examples; the scale on the first will be set to Fahrenheit based on how it is defined in the item state presentation pattern and the second one will be set based on your openHAB system regional settings (US=Fahrenheit; SI=Celsius).

Number:Temperature Temperature1 "Temperature [%.1f °F]" {alexa="TemperatureSensor.temperature"}
Number:Temperature Temperature2 "Temperature"           {alexa="TemperatureSensor.temperature"}

`ThermostatController.targetSetpoint`

Items that represent a target setpoint for a thermostat. The scale is determined based on: (1) value set in parameter scale="Fahrenheit"; (2) unit of item state presentation (°F=Fahrenheit; °C=Celsius); (3) your openHAB server regional measurement system or region settings (US=Fahrenheit; SI=Celsius); (4) defaults to Celsius. By default, the temperature range is limited to predefined setpoint values based on the scale parameter. If necessary, the temperature range can be customized using parameter setpointRange="60:90". When paired with ThermostatController.thermostatMode, setpoint requests will be ignored when the thermostat mode is off.
Supported item type:
- Number(:Temperature)
Supported metadata parameters:
- scale=<scale>
  - Celsius [4°C -> 32°C]
  - Fahrenheit [40°F -> 90°F]

Default category: THERMOSTAT

`ThermostatController.upperSetpoint`

Items that represent a upper or COOL setpoint for a thermostat. This needs to be paired with ThermostatController.lowerSetpoint. The scale is determined based on: (1) value set in parameter scale="Fahrenheit"; (2) unit of item state presentation (°F=Fahrenheit; °C=Celsius); (3) your openHAB server regional measurement system or region settings (US=Fahrenheit; SI=Celsius); (4) defaults to Celsius. By default, the temperature range is limited to predefined setpoint values based on the scale parameter. If necessary, the temperature range can be customized using parameter setpointRange="60:90". When paired with ThermostatController.thermostatMode, setpoint requests and responses will be limited based on the current thermostat mode as follows: (1) thermostat mode cannot be off to set/adjust a setpoint temperature; (2) set/adjust upper or lower setpoint to single point target temperature in dual mode with, respectively, thermostat cooling or heating mode. (3) thermostat auto and eco mode will be considered in dual mode if setpoints defined, otherwise in single mode. Additionally, for integration that uses separate upper and lower setpoints for eco mode (e.g. Nest), suffix #eco can be appended to the metadata property ThermostatController.upperSetpoint#eco to differentiate that property from the standard ones. For triple mode support, the setpoint mode automation will need to be disabled by adding parameter supportsSetpointMode=false to the thermostat mode item configuration.

By default, the temperature range is limited to predefined setpoint values based on the scale parameter. If necessary, the temperature range can be customized using parameter setpointRange="60:90". When paired with ThermostatController.thermostatMode, setpoint requests and responses will be limited based on the current thermostat mode as follows: (1) thermostat mode cannot be off to set/adjust a setpoint temperature; (2) set/adjust upper or lower setpoint to single point target temperature in dual mode with, respectively, thermostat cooling or heating mode. (3) thermostat auto and eco mode will be considered in dual mode if setpoints defined, otherwise in single mode. Additionally, for integration that uses separate upper and lower setpoints for eco mode (e.g. Nest), suffix #eco can be appended to the metadata property ThermostatController.lowerSetpoint#eco to differentiate that property from the standard ones. For triple mode support, the setpoint mode automation will need to be disabled by adding parameter supportsSetpointMode=false to the thermostat mode item configuration.

The mapping can be, in order of precedence, user-defined (AUTO=3,...) or preset-based related to the thermostat binding used (binding=<value>). For the binding parameter, it will be automatically determined if the associated item is using a 2.x addon (via channel metadata). If neither of these settings are provided, for thermostats that only support a subset of the standard modes, a comma delimited list of the Alexa supported modes should be set using the supportedModes parameter, otherwise, the supported list will be compiled based of the default mapping.
Supported item type:
- Number
- String
- Switch (Heating only)
Supported metadata parameters:
- OFF=<state>
- HEAT=<state>
- COOL=<state>

Items that represent the current temperature. The scale is determined based on: (1) value set in parameter scale="Fahrenheit"; (2) unit of item state presentation (°F=Fahrenheit; °C=Celsius); (3) your openHAB server regional measurement system or region settings (US=Fahrenheit; SI=Celsius); (4) defaults to Celsius.
Supported item type:
- Number(:Temperature)
Supported metadata parameters:
- scale=<scale>
  - Celsius
  - Fahrenheit
Default category: TEMPERATURE_SENSOR

`LockController.lockState`

Items that represent the state of a lock (ON lock, OFF unlock). When associated to an item sensor, the state of that item will be returned instead of the original actionable item. Additionally, when linking to such item, multiple properties to one state can be mapped with column delimiter (e.g. for a Z-Wave lock: LOCKED="1:3",UNLOCKED="2:4",JAMMED=11).
Supported item type:

Default category: SMARTLOCK

`ColorController.color`

Items that represent a color
Supported item type:
- Color
Default category: LIGHT

`ColorTemperatureController.colorTemperatureInKelvin`

Items that represents a color temperature, default increment value may be specified in metadata parameters. For dimmer typed items adjustments, INCREASE/DECREASE commands will be sent instead if increment value not defined, while number typed items will default to 500K increments. Optionally, the supported temperature range in Kelvin can be provided using parameter range="2700:6500". Preset-based range values will automatically be used based on the binding name and thing type (to differentiate color/white ranges), if the associated item is linked to one of the addons listed below (via channel metadata). Otherwise, to use these preset settings, use the parameter binding=hue or binding=hue:white. By default, the color type preset-based range values are used if the binding name is provided and the device/thing type cannot be determined. It is important to note that temperature adjustment requests for endpoints including a color item, will be rejected if the endpoint is in color mode (Dimmer => undefined temperature or color saturation > 0; Number => undefined temperature or temperature = 0). In that event, set the initial white level before requesting subsequent adjustments.
Supported item type:
- Dimmer: colder (0%) to warmer (100%) based on defined temperature range [bindings integration]
- Number: color temperature value in Kelvin [custom integration]
Supported metadata parameters:
- increment=<number>
  - value in % for dimmer item/in Kelvin for number item
  - defaults to increment=INCREASE/DECREASE (Dimmer) or increment=500 (Number) if omitted
- range=<minValue:maxValue>
  - values in Kelvin
  - defaults to 1000:10000 if omitted or no binding preset-based range values found
- binding=<value>

`ChannelController.channel`

Items that represent a channel. A channel mapping may be specified in metadata parameters allowing channel request by name. It is important to note only well-known channel names can be used as these are validated against a database on the Alexa side when requested. Unfortunately, Amazon doesn't provide a list of supported channel names.
Supported item type:

Supported metadata parameters:
- <channelName1>=<channelNumber1>
- <channelName2>=<channelNumber2>
- ...
Default category: TV

`InputController.input`

Items that represent a source input (e.g. "HDMI 1", or "TUNER" on a stereo). A list of supported input values needs to be provided using the supportedInputs parameter. The space between the input name and number is not sent to OH (e.g. "HDMI 1" [alexa] => "HDMI1" [OH]). That space can also be omitted in the supported list as well.
Supported item type:
- String
Supported metadata parameters:
- supportedInputs=<inputs>
  - required list of supported input values (e.g. "HMDI1,TV,XBOX")
Default category: TV

Default category: OTHER

`EqualizerController.bands:{bass,midrange,treble}`

Items that represent the different equalizer bands and their ranges supported by an audio system. Use specific capability component (bass, midrange or treble) when configuring a band (e.g. EqualizerController.bands:bass). Add the band range values in the range="-10:10" parameter. For the reset default value, provide the setting in default=0 parameter or it will be calculated by using midpoint range spread. Additionally, default adjust increment can be configured in increment=2 parameter. When configuring multiple bands, make sure to synchronize the range parameter across relevant items as the same range values will be used for all bands due to Alexa restriction. However, the reset and increment default values can be different between bands.
Supported item type:
- Dimmer
- Number
Supported metadata parameters:
- range=<minValue:maxValue>
  - defaults to "0:100" for Dimmer and "-10:10" for Number item types if omitted

  - defaults to midpoint range spread if omitted
- increment=<number>
  - defaults to increment=INCREASE/DECREASE (Dimmer) or increment=1 (Number) if omitted
Default category: SPEAKER

`EqualizerController.modes`

Items that represent a list of equalizer modes supported by an audio system. Set supported modes using supportedModes="MOVIE,MUSIC,TV" parameter. The mode listed in additional properties (MOVIE, MUSIC, NIGHT, SPORT, TV) are the only ones supported by the Alexa API currently. For the mapping, default item type mapping (listed below) can be used or if necessary, add each state to the parameters similar to how it is done with other interfaces.
Supported item type:
- Number [MOVIE=1, MUSIC=2, NIGHT=3, SPORT=4, TV=5]
- String [MOVIE="movie", MUSIC="music", NIGHT="night", SPORT="sport", TV="tv"]
Supported metadata parameters:
- MOVIE=<state>

Default category: MOTION_SENSOR

`SecurityPanelController.armState`

Items that represent a device that controls a security system. Set supported arm states using supportedArmStates="DISARMED,ARMED_STAY,ARMED_AWAY" parameter. For the mapping, default item type mapping (listed below) can be used or if necessary, add each state to the parameters similar to how it is done with other interfaces. If using a String item type, supports for pin codes (ability to have the disarm pin code verification done in openHAB) can be configured using supportsPinCodes=true. For system that have an exit delay, provide the delay in seconds using parameter exitDelay=180. If defined, the delay is provided to Alexa during arm away requests only. For the pin code, you will need to enable voice pin in the Alexa app for the relevant device. If pin codes support is set to true, disarm request will include the pin code in item command delimited by a column sign (e.g. disarm:1234), otherwise, the verification is done by Alexa based on the voice pin code you configured. When the pin code is attached to the item command, it is your responsibility to validate the code on the openHAB side and change the item status to UNAUTHORIZED corresponding state in order to indicate that the code is invalid. Otherwise, if no action is taken, the skill will consider the request successful. Other errors state can also be used based on the list of additional properties below. These should only be used when arm/disarm commands are received. When associated to an item sensor, the item command and state can be decoupled. Although at this time, the skill doesn't support delayed responses, so there should be no delay in updating the relevant item state.
Supported item type:
- Number [DISARMED=0, ARMED_STAY=1, ARMED_AWAY=2, ARMED_NIGHT=3, NOT_READY=4, UNCLEARED_ALARM=5, UNCLEARED_TROUBLE=6, BYPASS_NEEDED=7]

`ModeController.mode`

Items that represent components of a device that have more than one setting. Multiple instances can be configured in a group endpoint. By default, to ask for a specific mode, the item label will be used as the friendly name. To configure it, use friendlyNames parameter and provide a comma delimited list of different labels (Keep in mind that some names are not allowed). Additionally, pre-defined asset ids can be used to label a mode as well prefixing with an @ sign (e.g. friendlyNames="Wash Temperature,@Setting.WaterTemperature"). If the component isn't controllable through openHAB, set parameter nonControllable=true, that way only status requests will be processed. In regards to supported modes and their mappings, by default if omitted, the openHAB item state description options, if defined, are used to determine these configurations. To configure it, use supportedModes parameter and provide a comma delimited list of mode mappings composed of openHAB item states and the associated names/asset ids they should be called, delimited by equal and column signs (e.g. supportedModes="0=Cold:Cool,1=Warm,2=Hot"). For string based modes, if the mapping state value and name are the same (case sensitive), a shortened format can be used, where the name doesn't need to be added to the list by either leaving the first element empty or not providing the names at all (e.g. supportedModes="Normal=:Cottons,Whites" <=> supportedModes="Normal=Normal:Cottons,Whites=Whites). Additionally, if the mode can be adjusted incrementally (e.g. temperature control), set parameter ordered=true, otherwise only requests to set a specific mode will be accepted. For text-based name language support, your server regional settings should be setup, otherwise, you can optionally set the language in parameter language="en". For semantic extensions support, set actions in parameter actionMappings="Close=Down,Open=Up,Lower=Down,Raise=Up" and states in parameter stateMappings="Closed=Down,Open=Up". For actions, you can configure a set request by providing the mode or an adjust request, if ordered=true, by providing the delta value in parentheses.

Default category: OTHER

`RangeController.rangeValue`

Items that represent components of a device that are characterized by numbers within a minimum and maximum range. Multiple instances can be configured in a group endpoint. By default, to ask for a specific range, the item label will be used as the friendly name. To configure it, use friendlyNames parameter and provide a comma delimited list of different labels (Keep in mind that some names are not allowed). Additionally, pre-defined asset ids can be used to label a mode as well prefixing with an @ sign (e.g. friendlyNames="@Setting.FanSpeed,Speed"). If the component isn't controllable through openHAB, set parameter nonControllable=true, that way only status requests will be processed. To set the supported range, provide a column delimited list including minimum, maximum and precision values (e.g. supportedRange="0:100:1"). The latter value will be use as default increment when requesting adjusted range values. Optionally, named presets can be defined, by providing a list of comma delimited preset mappings composed of a range value and its friendly names/asset ids column delimited (e.g. fan speeds => presets="1=@Value.Minimum:@Value.Low:Lowest,10=@Value.Maximum:@Value.High:Highest"). Another optional settings is unitOfMeasure parameter which gives a unit of measure to the range values. It is determined based on: (1) unit id set in parameter unitOfMeasure=Angle.Degrees; (2) supported unit of item state presentation; (3) default unit of measurement for item type with dimension based on your openHAB server regional settings; (4) defaults to empty. For text-based name language support, your server regional settings should be setup, otherwise, you can optionally set the language in parameter language="en". For semantic extensions support, set actions in parameter actionMappings="Close=0,Open=100,Lower=(-10),Raise=(+10)" and states in parameter stateMappings="Closed=0,Open=1:100". For actions, you can configure a set request by providing the number value or an adjust request by providing the delta value in parentheses.

Supported Group Metadata

Functional groups (no group type) can be labelled with one of Alexa display categories. It can be set using one of the two formats: Endpoint.<category> or <category> (e.g {alexa="Endpoint.Thermostat"} or {alexa="Thermostat"}).
Display categories with underscores can be defined in camel cased format (e.g. {alexa="Endpoint.SecurityPanel"} => SECURITY_PANEL).
Child item categories are ignored and only the group category is used to represent the endpoint.
Case is ignored on the category part of the metadata and any value will be made all uppercase before its passed to the Alexa API.

Supported Metadata Labels

Item metadata labels translate to a set of capabilities and can be used as a convenience to using the longer meta data format configuration. These add additional functions and provide the ability to add customization through additional parameters which take precedence over the default ones. Here are some examples:

Switch TelevisionPower "Television Power" {alexa="Switchable" [category="TV"]}

Color LightColor "Light Color" {alexa="Lighting"}

Display Categories

Alexa has certain categories that effect how voice control and their mobile/web UI's display or control endpoints. An example of this is when you create "Smart Device Groups" in the Alex app and associate a specific Echo or Dot to that Group (typically a room). When a user asks to turn the lights ON, Alexa looks for devices in that group that have the category "LIGHT" to send the command to.
You can override this default value on items by adding it as a parameter to the metadata (e.g. Switch LightSwitch "Light Switch" {alexa="PowerController.powerState" [category="OTHER"]}).
List of Alexa categories currently supported from Alexa Skill API docs:

Category	Description
ACTIVITY_TRIGGER	A combination of devices set to a specific state. Use activity triggers for scenes when the state changes must occur in a specific order. For example, for a scene named "watch Netflix" you might power on the TV first, and then set the input to HDMI1.
CAMERA	A media device with video or photo functionality.
COMPUTER	A non-mobile computer, such as a desktop computer.
CONTACT_SENSOR	An endpoint that detects and reports changes in contact between two surfaces.
DOOR	A door.
DOORBELL	A doorbell.
EXTERIOR_BLIND	A window covering on the outside of a structure.
FAN	A fan.
GAME_CONSOLE	A game console, such as Microsoft Xbox or Nintendo Switch
GARAGE_DOOR	A garage door. Garage doors must implement the ModeController interface to open and close the door.

OTHER	An endpoint that doesn't belong to one of the other categories.
OVEN	An oven cooking appliance.
PHONE	A non-mobile phone, such as landline or an IP phone.
SCENE_TRIGGER	A combination of devices set to a specific state. Use scene triggers for scenes when the order of the state change is not important. For example, for a scene named "bedtime" you might turn off the lights and lower the thermostat, in any order.
SCREEN	A projector screen.
SECURITY_PANEL	A security panel.
SMARTLOCK	An endpoint that locks.
SMARTPLUG	A module that is plugged into an existing electrical outlet, and then has a device plugged into it. For example, a user can plug a smart plug into an outlet, and then plug a lamp into the smart plug. A smart plug can control a variety of devices.

Item Tag v2 Support

Version 2 (v2) of the Alexa skill used openHAB HomeKit style tags to expose items to Alexa. Version 3 (v3) of the skill supports this by translating v2 style tags to v3 metadata labels internally. These tags are still required if the items are being exposed to the HomeKit or Google Assistant integrations. Below is the translation of v2 tags to v3 labels.

Troubleshooting

Here are some of the most common generic errors you may encounter while using this skill:

Command Not Working

Alexa will respond with "That command doesn't work on device"
It indicates that the command that Alexa is trying to send to openHAB doesn't work, either because the intended device is not configured properly to support that command or because your openHAB items configuration has changed and a previously discovered item may longer accept certain commands. For example, a dimmer item type that was initially setup and was changed to a switch type, will cause Alexa brightness control commands to fail.
To resolve this error, make sure to update your openHAB items configuration accordingly and run a discovery update either through the Alexa app or just by asking "Alexa, discover" on your echo device.

Device Not Found

Alexa will respond with "I couldn't find a device or group named device in your profile"
It indicates that, either a device currently setup in your Alexa account, no longer exists in your openHAB server, or vice-versa.
To resolve this error, make sure to run a discovery update either through the Alexa app or just by asking "Alexa, discover" on your echo device. Keep in mind that previously discovered devices that have been removed from the openHAB configuration will show as offline under your Alexa account and not be automatically removed. To prevent potential device name conflicts, it is highly recommended to remove these devices through the Alexa app.
If all your Alexa-enabled devices in openHAB aren't discovered or getting updated:
- Check that your server is available.
- Look for any relevant errors in your openHAB server logs.
- If only new devices aren't found, make sure your last Alexa-related config changes are valid.
- If necessary, stagger the discovery process by adding a couple devices at a time to isolate the culprit.

Device Not Responding

Alexa will respond with "device isn't responding, please check its network connection and power supply", and in some rare occasions, no response or acknowledgement will be given.
It indicates that the state of one or more of the endpoint properties retrieved from the openHAB server are considered invalid, mostly because it is in either uninitialized NULL or undefined UNDEF state.
To resolve this error, make sure that all items interfacing with Alexa have a defined state. If necessary, use item sensors, or if the state is not available in openHAB, set the item state to not be retrievable.
For group endpoints, partial properties responses will be send back to Alexa excluding items with invalid state. This will allow Alexa to acknowledge a command request assuming that the relevant item state is accurate. However, it will cause Alexa to generate this error when requesting the status of a device configured with an interface supporting that feature. For example, using a thermostat group endpoint, a request to set its mode will succeed but requesting its mode status will fail if one of its property state, such as its temperature sensor, is not defined in openHAB.
This is the default error.

Request Not Supported

Alexa will respond with "device doesn't support that"
It indicates that a requested command is not supported by any of the device configured interfaces.
To resolve this error, make sure that the relevant interfaces are configured properly on the given device. If this is the case, the response implies a limitation on the Alexa side. This will happen for a device with specific interfaces that don't support certain voice requests as of yet, such as the state of a PowerController or BrightnessController interface.

Server Authentication Issue

Alexa will respond with "Sorry something wrong, to control device try disabling the skill and re-enabling it from your Alexa app"
It indicates that Alexa isn't able to control the given device because of an authentication issue.
To resolve this error, for users that are using the official skill, just disable and re-enable it through the Alexa app. For users that have setup their own custom skill, make sure that the proper credentials were added to the lambda function config.js.

Server Not Accessible

Alexa will respond with "Sorry the hub that device is connected to is not responding, please check its network connection and power supply"
It indicates that your openHAB server is not accessible through myopenHAB cloud service.
To resolve this error, make sure that your server is running, your openHAB cloud service is configured with mode set to "Notifications & Remote Access", and showing online under your myopenHAB account. For users that have setup their own custom skill, make sure that the proper server base URL was added to the lambda function config.js.
For users running openHAB 2.4, there is a known issue when running the Amazon Echo Control binding, associated to that release, that affects the server accessibility. The workaround is to use the latest stable release candidate version of that binding instead.

Temperature Out Of Range

Alexa will respond with "I can only set the temperature between minValue and maxValue"
It indicates that a requested target temperature is out of range, based on the target, upper, or lower setpoint default range values.
To resolve this error, add the metadata parameter setpointRange="<minValue>:<maxValue>" on your relevant thermostat setpoint items to customize your range values and run a discovery update either through the Alexa app or just by asking "Alexa, discover" on your echo device.

Example Voice Commands

Here are some example voice commands:

Alexa turn on Office Lights
Alexa turn off Pool Waterfall
Alexa turn on House Fan
Alexa turn on Home Theater Scene
Alexa dim Kitchen Lights to 30 percent
Alexa set house temperature to 70 degrees

Other openHAB Alexa Integrations

openHAB has two other Alexa integrations that can be used in conjunction with or independently of this skill.

Amazon Echo Control Binding

Control Amazon Echo devices from your openHAB. This allows openHAB to send commands to a echo device and control its ability to play music, set alarms, change the volume and use it a Text-To-Speech output device. See the Amazon Echo Control Binding for more information..

Hue Emulation Service

Hue Emulation exposes openHAB items as Hue devices to other Hue HTTP API compatible applications like an Amazon Echo, Google Home or any Hue compatible application. This is done on the local network and does not require the cloud service. See the Hue Emulation Service for more information.
