I didn’t notice a big problem when it was on. There is enough air circulation in the area where the radiator is, for the temperature to not rise significantly above the rest of the room and seem inaccurate. I haven’t tried using an independent thermometer to confirm that, though.
[…] ZigBee thermometers with humidity sensors anyways. Do you know any cheap ones by chance?
No, sorry I initially went with esphome based hardware, until I realised that Zigbee is (should be?) better for battery life. I’d be interested to hear what you end up using though.
Do you use rechargeable batteries for the valves? Because the run on 1.2V that might be the issue.
No I’m fairly sure I didn’t, but I’m not able to get to it to check at the moment.
I had assumed that it was something similar to this sort of problem, because the serial gateway process on the bridge keeps crashing.
