AllSky Dew Heater Module Status: Stable Level: Experienced Runs In: Periodic This module allows for control of a dew heater via a relay connected to one of the Raspberry Pis GPIO pins. The module requires an external temperature and humidity sensor. Currently the following sensors are supported - SHT31 - DHT11 - DHT22 - AHTx0 - BME280 - HTU21 - SOLO-Cloudwatcher The module contains the following options Sensor Type: The type of external sensor being used Input Pin: The GPIO pin used for non i2c sensors such as the DHT11/22 i2c Address: Override the default i2c address for the selected device Heater Pin: The GPIO pin the heater relay is connected to Extra Pin: Extra pin that will be triggered with heater pin Heater Startup State : The state of the heater when starting Allsky Invert Relay : Normally the GPIO pin will be set High when the heater is required. This option will set the GPIO pin Low when the heater is required Invert Extra Pin: Normally a GPIO extra pin will go high when enabling the heater. Selecting this option inverts extra pin to go low when enabling heater Delay: The time in seconds between readings Limit: If the temperature is this number of degrees above the dew point the heater will be enabled Forced Temperature: Below this temperature the heater will always be enabled
