Hi
When changing the unit is Raspberry Pi online?

Yes the unit raspberry is online. I set up the widget in the correct way and next access generally I lost all my personalization with temperature but often also the type of widget choose before also in other widget as switch A

----Messaggio originale----

Yes I upload data in Celsius say the value 20.0°C and then it gets converted to Fahrenheit and displayed in those units as 68°F ! Nothing I can do changes the widget, actually and frankly it’s not working… uploading using Cayenne.celsiusWrite(V3, sht30.cTemp) does not work either at least Cayenne.virtualWrite(V3, sht30.cTemp) does albeit with the conversion to F. I can’t believe anyone is using this service with such basic errors like this in it.
