Was looking into ways to hook up my pellet stove via Home assistant. Got A Shelly1 Relay and a Shelly H&T integrated into home assistant. If I hook up the H&T to power it will update every 5 minutes. That seems to be enough is the scheme of things as I don’t see the pellet stove warming up an area in less then 5 minutes. In your opinion would you do something else? Current stove configuration doesn’t allow a clean installation of a normal thermostat.
I’m not sure if home assistant allows you to create a virtual thermostat entity or something like that using a separate temperature sensor and smart relay, but if it does, then this will work.
