**Describe The Problem:**
HomeKit notifications for camera motion and ring events are not being delivered as expected. Some cameras never send notifications, others do erratically. 

**To Reproduce:**
Unclear. I have confirmed that Homebridge and my Unifi Protect controller are set to the same time, as per plugin troubleshooting documentation.

**Logs:**
<!-- In order to be helpful, include the relevant logs from Homebridge, if applicable. -->
No relevant logs; please let me know if there is a verbose logging option that would provide relevant detail.

**Homebridge Configuration:**
