(mäter ute tempen).
The Vera unit displays on the user interface the value sent by the sensor. It changes the value only when you wanna see the temperature in Fahrenheit.
Please bring the sensor near the Vera unit and log in and connect to your unit and go to Users & Account Info > Unit Settings and under Weather settings change the temperature format to Celsius. (If it’s already Celsius change it to Fahrenheit click Save Changes and the change it back to Celsius and click Save Changes )
Afterwards wake up the sensor.
Also, you can try to exclude and re include the sensor after changing the temp format and clear the cache on your browser.
