Does anyone else notice these radiator valves are a bit useless with the Tapo Smart Temperature & Humidity Monitor? I have readings up to 2 or 3 degrees hotter than the actual room temps, they turn off heating too quickly and fail to actually control the temps properly. With the remote sensors though they are game changers. TP-Link should really include a remote sensor with each thermostat. What does the temperature correct actually do? It doesn't seem to be a calibration function does it just change the displayed temperature?,
