Hello, I present to you a T2 relay that replaced a thermostat on a central heating system. I’m going to make the scenarios. For automation, in addition to the relay, I have three radiator thermostats and three w100 temperature sensors. I’ll come back with new information.
Optimal automations made by me…
Same. It’s a disappointment the W100 has to be bound to a radiator thermostat and does not expose automation triggers natively.

Personally, I am unable to do the following automation: when a thermostat has reached the set temperature and in another room the temperature has not reached the set one, do not turn off the boiler. Only turn off the thermostat in the room where the temperature has reached the set one. The boiler should continue to run until the temperature in all rooms reaches the desired one.
You need two automations
If (temperature_below_set) or (temperature_below_set)
Turn On Relay
End
And
If (temperature_above_set) and (temperature_above_set)
Turn Off Relay
End
See Automation 2: Disappointing removal of feature - #7 by nzjrs for the And/All condition in V2.
Fwiw this is not a very good heating system because of lack of hysteresis and multiple triggers will cause your boiler to do a lot of start/stop cycles, but it does work - this was my previous heating automation.
