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.
Thats a complete thermostat, the problem sounds like it’s not in the room it’s heating (for the most part). Typical of a renovation that split an old room apart but they were too cheap to rework the radiators.
There are several TRV’s that can use remote temp sensing eve thermo comes to mind but any of them should do the trick.
You can fudge it with the shelly a hub and any temp sensor in the room.
Well, you are talking about analog, “moded” devices (rotating knob, slider). By that, I mean, they have a single spot that they can be at any time. The slider at the top is the hottest, and at the bottom, it’s the coldest.
But how does that jibe in any way with a smart device, which is almost always “modeless”. It can take the temperature by requesting it. It can change the temperature electronically by sending a “change temp” sequence. But it has not way of moving a physically-moded switch.
