@sundberg84 Nice, I had hanging issues with Domoticz in the past, until I decided to switch to Home Assistant. Best decision ever.

@Michał-Szura I had problems with relay and HA too. The best solution was to save the state of the relay in the EEPROM and to recall the value after a defined amount of time and send it to HA in loop(). This way you do not have to restart the relay node everytime you restart HA.

I have tried Domoticz, Mozilla WebThings and Home Assistant. So far the best is Home Assistant, it has many integrations and a nice UI. If you want to be able to access it outsite your network I recommend ZeroTier (had many issues trying thru the router).
