We have a traditional thermostat in an awkward to reach place, so I’d like to replace it with something I can stick to the wall.
I’ve got a few shelly devices running already, so the Shelly TRV comes to mind, but that only takes care of the receiving end. Ideally I want some kind of simple rotating knob or slider, battery powered and connected to wifi.
I have home assistant set up so anything that works with it is fine, though nothing that requires a cloud connection. I’d very much like to keep it budget friendly, so avoid fancy displays or even touch screens etc. Just give me something I can physically grab to crank the heat.
Is there any reason that you want to have the devices running on WiFi? There is plenty of available Zigbee thermostats.
Whenever I need something for my home automation, I go here: https://www.zigbee2mqtt.io/supported-devices/ and see if there are any devices that fit my needs.
Once I found them I look for retailers that have them in stock.
My latest purchase was these three things: https://www.zigbee2mqtt.io/devices/TV02-Zigbee.html
And they seem to work OK, although time will tell. I didn’t have much use for them, as the weather is still in double (Celsius) degrees here.
