Questions Regarding Google Home Support for Specific Matter Clusters and Attributes

[milesW]

I am developing a Matter device using the esp-matter SDK and the ESP32-C6.
I am testing the `On/Off Plugin Unit endpoint` and the `Mode Select endpoint` with Google Home.

I have some questions because I am wondering whether the following clusters and attributes are supported in Google Home. From what I can tell, it seems they are not yet supported.

1. Can the StartUpOnOff attribute of the On/Off cluster be used in Google Home?

2. Can the User Label cluster be used in Google Home?

3. Can the Mode Select cluster be used in Google Home?

If there are any resources or documentation listing which clusters and attributes are supported by Google Home, I would really appreciate it if you could share them with me. I tried to look for this information but was not able to find it.

Hi, great questions! As of now, Google Home doesn’t fully support the StartUpOnOff attribute, User Label cluster, or Mode Select cluster in Matter integrations. Official documentation is still limited, but I’d recommend checking the Google Home Matter support page for any updates as new clusters are added gradually.
