Description

I have the problem that BT sends to small offset to deconz. At the difference of 2.0°C, BT send also as offset 2.0. But for deconz and the thermostat is 2.0 = 0.002°C

For Offset -2.0°C I have tosend -200 insted of -2.0 For Offset -0.2°C I have tosend -20 insted of -0.2

Versions

1.4

Additional Information

[folfy]

I saw some option to implement a calibration in a device-specific quirk with BT - Making a comment for myself to check into this.

@folfy Is there anything new in this regard?

[wovka88]

I did a quick fix for myself first, so far it's working.

But I don't think it's the final solution:
