Inconsistent Home app operation following 1.3.1 upgrade - iPhone works, Mac OS + HomePod do not
**Describe The Bug:**
Following upgrade from v1.2.5 to v1.3.1 all accessories can be operated from the Home app on iOS. None of the accessories respond when using the Home app on MacOS or via Siri on HomePod - just get a 'Not responding' message.

**To Reproduce:**

- Install v1.3.1
- Test accessories are working correctly in iOS
- Test accessories are working in Home app on MacOS
- Test accessories are working via Siri on HomePod
- Logs show requests from iOS devices correctly. No requests from MacOS or Siri are received/logged by Homebridge.

**Expected behavior:**
<!-- A clear and concise description of what you expected to happen. -->
Accessories should work on all platforms, not just iOS

**Temporary workaround:**

Rollback to v1.2.5
