Verify Matter Modules & Services

Stay organized with collections Save and categorize content based on your preferences.

Before attempting to setup and pair a Matter device in the Google Home ecosystem, verify your mobile device has all the required Matter modules downloaded.

Check the Android settings

Your Android mobile device should get all modules automatically, but sometimes it can be delayed.

To verify, on your mobile device, go to Settings > Google > Devices & sharing.

  • If the Matter devices & services option is listed, you have what you need. Jump to Pair a Matter device to continue.

  • If the Matter devices & services option is NOT listed, you will need to force the download if you want it right away (otherwise simply wait for it to roll out on its own) using one or more of the options below.

Update Google Play services

Google Play services should be version 22.30 or higher. To check, on your mobile device, go to Settings > Apps > See all apps > Google Play services. Scroll to the bottom, where the version is listed.

If the version is not at least 22.30, force an update:

  1. On your mobile device, navigate to https://play.google.com/store/apps/details?id=com.google.android.gms or use the QR code below:

  2. If this page shows an Update button, tap it to ensure you get the required Matter module.

  3. You may have to wait 24 hours for the Matter modules to download. Ensure your device is powered on and charging during this time, so the download isn't delayed. If you haven't received the modules within 24 hours, you can try a factory data reset of the device to force the modules to download.

After a successful update, check for the Matter devices & services option again.
