Hi Sebastian,

The developers confirmed that this was a bug. This will be fixed in the next release of the Zigbee add-on. In the meantime, here is the sensor.c file with the fix.

Sensor is working fine, only when temperature measured is below 0*C, log format has this issue.This is because how a sensor stores the value:

And in the log the measurement is printed as two values (integer and fractional) - when temperature is below 0*C, fractional part can be negative and will be printed with minus character.

So the temperature can be displayed as: [0.-980000] or [-1.-210000] but should be [-0.980000] or [-1.210000]

Hi Sebastian,

The application shows the correct format on my side.

It could be that your sensor is defective, or there is an issue with the communication between the sensor and the nRF5340. Can you try the BME68X: Gas Sensor sample and see if you get strange measurements with that as well?

Best regards,
Marte
