[Matter] Device cannot be commissioned to Google Home through iOS

SonTran_Qorvo — Wed, 31 Dec 2025 08:23:20 GMT

Hi,

We are facing the issue of commissioning our Matter device to google home through iOS device will be 100% failed.

Here is our test summary regarding the issue:

TestCase1 [OK]: Commissioning our Matter 1.4.0 device to Google Nest Hub 2 by Android device
TestCase2 [NG]: Commissioning Matter 1.4.0 device to Google Nest Hub 2 by iPhone13 or iPhone16 (see log
TestCase3 [OK]: Commissioning our Matter 1.3.0 device to Google Nest Hub 2 by iPhone13
In TestCase2, we noticed that device was first commissioned to iOS(Apple keychain) then iOS opened a commissioning window again to commission it in Google’s ecosystem, and the device was failed at above step 2, so we also tried:
1. Commissioning the device to Apple Home works as expected, next share the device to Google Home app on iOS, this also fails.
2. Commissioning the device to Apple Home works as expected, next share the device to Google Home app on Android, this works as expected and device pops up in Google home of iOS as well.
Could you help check what's the issue of TestCase2?
Append the environment of our testing:
- NestHub 2 version, system firmware version: 28.20250723.103.2100300
- Google Home APP version 4.3.51

is this issue fixed? And what is the root cause? I have been facing simialr issue, and i know that sometimes using a different iPhone and log on to the same google account will make it work.
