# Bug Report

### Describe the Bug
I have loaded the Homebridge-ring plugin into the Homebridge-UX and followed configuration instructions.  After restarting Homebridge I see no errors in the log, but not accessories are available in the home app.

### To Reproduce
Restart Homebridge
look in the logs for errors, non.
Open Home app and expect to see my ring accessories.  Nothing is available.

### Expected behavior
Open Home app and expect to see my ring accessories.
See my ring alarm sensors and view their status via the Home app.
Create some automations based on the sensors values.
