# Bug Report

### Describe the Bug

When upgrading the plug-in in Homebridge to anything beyond version 9.24.0, the plug-in works as intended immediately after I restart Homebridge. A short time later, if the doorbell button is pressed it no longer shows in the log as registering that the button was pressed, meaning there are no notifications sent to HomePod, iPhone, etc. I am still able to watch the video and stream it from my iPhone and Apple TV, but the button press is just no longer registering that anything has happened at the doorbell.

### To Reproduce
Steps to reproduce the behavior:
 - Start Homebridge
 - Upgrade plug-in to anything after 9.24.0
 - Wait 
 - Test doorbell button
 - Verify in Homebridge log that nothing has registered, after not getting a notification the button was pressed.

### Expected behavior
- Ongoing notifications that the doorbell has been pressed.


### Screenshots/Logs
I'm not sure what I can provide, given the logs show that nothing is happening. Happy to provide anything needed to troubleshoot.
