The TRV is running out of calibration when trying to close to 0 from small steps like 1 or 2%.
So it will loose the calibration more often. I noticed this behaivor especially after using the adaptive mode.
The weekly calibration is pretty useless. The TRV will run out of calibration after 1 or 2 days. We need a feature to force calibration.
And we need a mode, where the TRV extra applies force to the motor when closing. (More current. Should be possible with a stepper motor).
