Temperature Fields on Matter Devices do not convert to User Preferences

[Omnipius]

For any Matter device that shows a temperature (sensor, thermostat, etc), the Google Home app and Assistant/Gemini only displays, reads out, and accepts values in Celsius, regardless of the user's temperature unit preferences. While it is true that all communication (Matter or otherwise) should be done in Celsius, the units displayed in the app, read out by Assistant/Gemini, or used in commands and/or automations should be assumed to match the user's temperature unit preference unless the user specifies otherwise** for a given device or command. This appears to have been an oversight in the development of Matter support or a bug in temperature unit implementation

** This means that all Matter device application clusters that represent physical temperature should have an in-app setting for temperature unit [C, F, or Auto (default)]

Hello,

Thanks for reporting this temperature unit conversion issue with Matter devices. You're right that Google Home should respect user temperature preferences when displaying and interpreting values from Matter devices.

This is a valuable insight. Please file a bug in Google's Issue Tracker  and post the bug ID back here so I can escalate it to the appropriate team.
