Changing the Default Display for a Matter TVOC Sensor?

[Skyhan]

Hi, I’m adding my Aqara M3 Hub to SmartThings via Matter, and everything is working fine. However, my TVOC sensors display air quality on the main screen. Is there a way to change this to show the temperature instead? Has anyone tried this?

Do you mean the device tiles?

If yes: it can theoretically be changed, but it would require a custom Matter driver…

Yes, this is what I was talking about. Could you please share the name of the driver?

I didn’t say that there’s one.

I guess the device is using the Matter sensor driver and all it would take is to change one or two lines in the profile (plus a sub driver, to do it right). Downside: if someone would do that for you, the custom Matter driver would be outdated in no time.

If you have hub you can copy temperature to virtual temperature device using RulesAPI rule.

RulesAPI rule example:
