I set Fahrenheit field to "1" in Defaults and forced interview on sensor ( Vision PIR with Temperature).
I get correct reading in Z-Way UI but with Celsius label, like this 78C... should be 78F.

How can I fix it?

Hello,

we have tested the device.

It cannot transmit the unit of the Temperature.

The default unit for temperature is °C.

Yes, I have tried both ways, when I set Vision PIR sensor to transmit in Fahrenheit - sensor just ignore it and send value in Celsius. So, in ZWay UI I have 25C as a temperature.

If I set Fahrenheit field in /opt/z-way-server/config/Defaults.xml file to "1" - the z-way-server will convert C into F internally by using formula ( C * 1.8 + 32 ) so UI will show number 77 BUT the label after that number is still char 'C' not the char 'F'.

So, how can I fix that "cosmetic" issue?

Hello,

please restart your Z-Way System.
Exclude your PIR Device and include it again.

Then you have the Temperatur in Fahrenheit.

Yes, that did the trick.
Previously, I just did forced re-interview and that did not update char "C" into "F".
