Calibrating Sonoff SNZB-02

anyone know how to calibrate the sonoff zigbee temp sensors without creating another template sensor? I’m using ZHA cause it seems more stable than the zigbee2mqttt but It also means i can’t find the config to add the calibration spec.

I have the same question. I know tasmota has a command to do this but not ZHA.

Yes please, my Sonoff SNZB-02 is +10% off compared to my Bosch Easycontrol CT200

Hi, I also have the feeling that humidity might be quite off.
I have nother sensor, not very realiable though, and the humidity measurament differs 7-10%.
Is this a general issue?

Thanks

Similar question to OP. Is there any way of assigning an offset to the temperature value as part of calibration?

I don’t have this particular sensor but do have the Aqara one and the temp needs adjusting. I could use a template sensor but would prefer if it was something that could be applied via ZHA.

Thanks in advance

did anyone figure this out?

I have the same problem with 6 sensors which I received recently. The temperature is measured correctly but the humidity is +7%-10% off (1 Sensor +18%) compared to different other hygrometers.

How did you solve the problems?

Thanks

If you are using Zigbee2MQTT you can use temp and humidity offset in the setting of the device

It would be nice to be able to do this with ZHA - has anyone found a solution ? I got the ZB2MQTT working but would like to stick to ZHA so I don’t need 2 seperate zigbee networks
