 | --- | --- |
 | `BUTTON` | This event is triggered when a button on a Hue Dimmer Switch, Hue Button or an other similar device is pressed. The button_state is `1` as long the as the button is pressed and `0` when released. <br/><br/>Note that for BUTTON events, the `{item_state}` has a format of `{button_number}/{button_state}`. This is because a single hue accessory can have multiple buttons. <br/><br/> Example: `hue_event/sensors/29/1/1`|
 | `MOTION` | This event is triggered when motion is detected by a Hue motion sensor. The state is `1` when motion is detected and `0` when no motion is detected. <br/><br/> Example: `hue_event/sensors/34/1`|
-| `LIGHT_LEVEL` | This event is triggered when the light level changes on a Hue light sensor. The state represents the current light level. To get the actual brightness in Lux, use this formula: 2.718281828459^(value*0.00023034)-1 <br/><br/> Example: `hue_event/sensors/35/10597`|
+| `LIGHT_LEVEL` | This event is triggered when the light level measured by a Hue motion sensor changes. The state represents the current light level in Lux. <br/><br/> Example: `hue_event/sensors/35/230` = 230 Lux |
 | `TEMPERATURE` | This event is triggered when the temperature changes on a Hue motion sensor. The state represents the current temperature as a float value. <br/><br/> Example: `hue_event/sensors/36/25.36` = 25.36°C|
 | `LIGHT` | This event is triggered when the state of a light changes. The state is `1` when the light is on and `0` when the light is off. <br/><br/> Example: `hue_event/lights/4/1`|
 | `GROUPED_LIGHT` | This event is triggered when the state of a light group changes. The state is `1` when the group is on and `0` when the group is off. <br/><br/> Example: `hue_event/groups/3/0`|
