So I’ve had this thermostat for a while and other the annoyance with Tuya cloud and wrongly reported temperature (fixed by using LocalTuya), it worked fine for me

Now recently I bought an Aqara Humidity+Temperature sensor and put it into the bathroom. Its readings seemed off as it reported a lower temperature than the Tuya thermostat. To check, I bought a dumb hygrostat from the hardware store and indeed it seems that the Tuya thermostat is usually off by about +0.5 to +1°C in all rooms I’ve tried. Anybody else experienced it? Can I somehow tell HA to just adjust all temperatures reported by this thermostat down by 1°C?

Yes, my Moes Thermostat was even off by +3 degrees.

I use it with Zigbee2mqtt, there you can set a compensation (in my case -3 degrees). Then the correct temperature is shown on the display and in Z2M an Homeassistant.
