The unit of the thermostat suddenly changed to Fahrenheit on Google Home app.
Previously, it was displayed in Celsius and was able to perform voice commands. Right now it's displayed in Fahrenheit in the Google Home app.
The manufacturer's equipment and provided app will continue to display Celsius. Displayed in Fahrenheit only in the Google Home app.
This is not the weather unit. Weather units are displayed in Celsius
