Moes BRT-100-TRV - Is local_temperature_calibration just a cosmetic value?

[ikarisan]

Hi!

At the moment I am using two Moes BRT-100-TRV and I am wondering iff the "local_temperature_calibration" is just a cosmetic value for the display/dashboard.

Why?

One of my BRT-100-TRV is located near the hot radiator. So it measures a 1-1.5°C higher temperature than the room actually has. I thought that I can compensate this by setting "local_temperature_calibration" to "-2°C". But this has no real effect on how much the ventile will be opened. My room is still at 20°C because the "postion" keeps on between 25% and 50%. If I set the "calibration temperature" to -4°C and the "current_heating_setpoint" to 22°C, the ventile will be opened to 100%. But I thought that the ventile opens as much as needed to reach the "current_heating_setpoint" temperature.

Is this a expected behaviour for "local_temperature_calibration"?
