Yes I want to use home assistant for controlling the relais on the board (based on a odroid system).
I want to use a thermostat and temperature sensors connected to HA to control the relais board (in the end temperature regulation). This system is already there and can be used.
So connecting temperature sensors directly to the ESP32 board is very difficult.
All problems related to the temperature sensors (e.g. one is defect) can be solved on HA side.
But for any case of failure like e.g. connection loss of ethernet, freeze of home assistant) I want to automatically switch all relays off to be in a safe state.
This is only relevant for the case, that nobody is at home, that the system does not do anything which could lead to problems.
So there needs to be some error handling.
