:sparkles: Features

  • Dual Trigger Support: Compatible with both the Last Doorbell Ring timestamp sensor (sensor.*_last_doorbell_ring) and the doorbell binary_sensor.
  • Smart Restart: If the doorbell is pressed again while the video is streaming, the countdown timer resets rather than cutting off the feed.
  • Nighttime Shield: Ignores unavailable and unknown state transitions so Nest Hub screens don’t wake up during overnight Home Assistant updates.
  • Multi-Screen Streaming: Casts to one or multiple Google Nest Hubs or Chromecast displays at the same time.
  • Custom Actions Hook: Optionally run extra actions alongside the stream (e.g. pause TV playback, play an indoor chime, or turn on porch lights).

:clipboard: Requirements

  • Any UniFi Protect Doorbell paired via the official UniFi Protect Integration.
  • One or more Google Nest Hubs or Chromecast media players paired via the Google Cast integration.

:light_bulb: Tips for Best Performance

  • Google Cast devices play video via HLS (HTTP Live Streaming), which typically buffers for 3–6 seconds before playback begins.
  • For best performance and minimal stutter on Nest Hubs, choose your doorbell’s Medium or High Resolution Channel entity.
