Having installed ST and following above advice for changing to Celsius within the locations. No luck. Going to wait for a few days. Grrr.
Are there any updates on this Samsung ? I am still getting this…
Mine changed to C within an hour of posting.
I am having the same problem, added sensors while the location was configured in Fahrenheit. Now changing it to Celsius but both multipurpose and water sensors still show temperature in Fahrenheit.
I have tried to change the settings both in the Android app and the graph.api web with no luck.
