Shelly 1PM Gen4 Device Type Issue in Google Home

Hey everyone, I’m encountering an issue with my Shelly 1PM Gen4 device when connected via Matter to Google Home. The device consistently appears as a sensor instead of a light, which is quite frustrating. Here’s what I’ve tried so far:

  1. Device Type Setting: I set the device type to “light” in the Shelly mobile app, but it didn’t make a difference.
  2. Consumption Type: I also tried changing the “Consumption type” in the Shelly web UI to “light,” but this field seems more related to energy monitoring.
  3. Multiple Attempts: I’ve added the device to Google Home over 10 times, and only twice did it initially show up as a light. Unfortunately, it reverted to a sensor after about 24 hours.

Questions:

  • How does Google Home determine the device type for Matter relays?
  • Is there a reliable way to ensure the Shelly 1PM Gen4 is recognized and stays as a light in Google Home?

Any advice or insights would be greatly appreciated! Let’s figure this out together.
