Hi all, I’m using a UniFi G4 Doorbell Pro and had an automation set up to play an MP3 file on my Sonos Play:1 speaker whenever someone pressed the ring button. Nothing fancy, but I always had a few issues that I’ve finally solved by (surprise!) actually reading the manual. 
I thought I’d share my upgraded automation in case it helps someone else as it seems all other post reference the method which causes the below issues:
Previous issues:
- Noticeable delay between the button press and MP3 playback
binary_sensor.unifi_doorbelldidn’t always trigger reliably- Random false triggers after camera or UniFi Console updates (e.g., at 2 a.m.)
The fix:
While reading the Home Assistant documentation for UniFi Protect, I noticed that the recommended approach is not to use the binary sensor, but instead to trigger the automation based on the UniFi Protect event and then filter for the event type "ring".
This method is not only faster, but also far more reliable and it ensures that only the actual “ring” event triggers the doorbell sound, eliminating those annoying false alarms.
Here is my automation YAML
