The first recommended check is to make sure the radiator is correctly paired with the app (LED off, radiator “connected” in the app).
If the radiator is not connected, then it will not be able to receive or send system updates, including those for the temperature.
If the temperature detected for the radiator is still not the same as the one detected by another device, it will be necessary to enter an ‘offset’ in the app (temperature gap up to +/- 5°).
The steps are: Menu --> Devices --> select the electric radiator --> enter the offset to bring the temperature into line --> the temperature in the app will therefore by the one updated to the offset.
For example: if the temperature detected by the radiator is 26°, but the temperature detected by a digital thermometer is 23°, it is possible to enter an offset -3° to bring the temperature into line.
This way, the temperature shown by the radiator in the app will be 23° (temperature detected – offset).
