Hi,
I am completely new to home assistant. i have set up a sensor ESP8266 and connected a DHT22 and a relay to get Temp humidity and a relay to switch on an extractor fan. I want to control the humidity by switching the fan on and off. i have found a Mold indicator configuration that i loaded into the config file however and configured to display on a panel however i am receiving an unavailable, i have been through the logs and cannot find anything to suggest that the sensor is at fault. i have the units set correctly on the temp and humidity. What am i missing? do i need to install something else to make this work?
