I just released a new version of my doorbell-mqtt-unifi project.
The project lets you control the UniFi G4 Doorbell Pro animations and sounds through MQTT, which makes it easy to automate from Home Assistant.
Some of the improvements include:
- Faster profile updates using an IPC (inter-process communication) apply method
- Image and sound apply and refresh the doorbell in less than 2 seconds
- No longer requires restarting processes on the doorbell
- Added a Validate Profile entity in Home Assistant to detect configuration drift from the doorbell restarting and reverting to the UniFi Protect settings
- Added a Reapply last profile entity in Home Assistant
- Ad-hoc sound effects
- Play sounds effects on the doorbell at anytime
- Select entity in Home Assistant to select the sound effect to play
- Asset validation and storage guardrails
- Validates the image and sound files are the right size
- Checks magic headers of file to validate they are an image and sound file
- Makes sure you don't exhaust the persistent storage on the doorbell
The Docker container runs on x86-64 and arm64. The C code will also compile on arm64 if you want to run the service without Docker.
