Hello! 
I “built” a thermostat from a relay module with an ESP-01S, along with a DHT22 temperature/humidity sensor. The ESP-01S runs with the HAA (Home Accessory Architect) system from “Raven System”. May be known. So far, I had been running this via the HomeKit app for the past few months and it worked perfectly and reliably.
Today I registered the system to my Home Assistant server. Quite normally via the Homekit controller integration. It is recognized as a thermostat and also the temperature and the values the humidity sensor are displayed.
The problem: I can not turn on the thermostat! I can pre-select a temperature, but I can’t turn anything on and the thermostat won’t turn on by itself. Also from no app the thermostat can be activated.
If I insert the example configuration in the configuration.yaml file, I get after the reset a second thermostat displayed.
Does anyone have a solution or tip?
I would be very happy and grateful.
Thanks in advance!
Take care…
