ds18b20 convert to celsius in ui icon

My temperature probes are reporting in the UI icon in degrees F. How can I change UI icon to display in Celsius.

I have another device a CurrentCost power meter which reports in C.

I figured I would kick off a scene on a temperature change that would execute some Luup code to calculate a new value and write that back. I’ve been stumbling around and have managed to define a new variable, and populate with my calculated C value. I cant figure how to update the UI icon… can someone help please?

In most cases, if you go into Setup → Location in the Vera web UI, you can change which temperature units shown.

The location field is set up correctly… England(UK) where we use Celsius.

My CurrentCost device reports in C, my temperature probes report in F.

Vera doesn’t know that the UK uses Celsius for temperature. Did you explicitly select “Metric - ?C” for “Temperature Format” on the same setup page?

My CurrentCost device reports in C, my temperature probes report in F.

As the author of the CurrentCost plugin I can vouch for it not being a good indicator of whether Z-Wave devices will display in Celsius or Fahrenheit. The CurrentCost plugin has no access to the user’s temperature preference, so it just reports whatever units your EnviR console uses. Presumably as a British unit it reports in Celsius, so that’s what the plugin displays.

I can confirm that my CurrentCost plug does report in Celsius.

I can also report a big doh… my Metric setting was indeed set to F. Setting it to C fixed this issue. Must be blind as well.

Thank you all for your patience…
