I’ve been using SONOFF smart TRVs for the past year to control my heating (Vortex Pro Indoor Combi Boiler). This works in conjunction with a basic wall programmer that sets the heating schedule for water and heating.
The programmer developed a fault and I had to switch the boiler over to 24x7, which was fine during the winter, but now it is getting warmer I need to find a replacement programmer.
To make things slightly more complicated, the boiler is in a utility room, so a combined programmer / thermostat would need to disable the thermostat function. It’s not so easy to determine if this is possible from the manufacturer’s websites.
I would like to replace the programmer with something that integrates with HA. Preferably allowing HA to turn it on or off or at least to report what it is doing. I have looked a several smart thermostats and so far have not been able to tell if they will work in my situation.
UK based. ZHA preferred.
Features wanted:
wall unit:
twin relay control for heating and water
programme schedule
connectivity:
report status to HA
report schedule to HA
set status from HA
set schedule from HA.
What is the state of the smart home heating control?
