Google Nest Battery Camera Setup

Third party integrations
1

Hello,

I’m reaching out as I’m running out of ideas and would like to figure out if my config is every going to work. I have a bunch of Google Nest Battery cameras for which I managed to integrate into Home Assistant. each camera is listed in the dashboard although they only display a black rectangle (1st issue). I can access the stream when clicking on it and see the video, however, if I click on “Download Snapshot”, I get a completely black picture (same as the one on the thumbnail).

I’m not overly bothered by the dashboard although it would be nice for these pictures to get updated once in a while. Ultimately, my objective is to save video recording of events. I have set up the automation for motion triggeres snapshots. This triggers with motion events which shows that motion detection works and so does the file saving part, however, I only get the aforementioned black pictures. If I set it up to save a recording, I get nothing. Portainer shows the following

2025-01-15 10:15:23.956 ERROR (MainThread) [homeassistant.components.automation.garage_motion_recording] Garage Motion Recording: Error executing script. Error for call_service at pos 1: camera.garage does not support record service

2025-01-15 10:15:23.958 ERROR (MainThread) [homeassistant.components.automation.garage_motion_recording] Error while executing automation automation.garage_motion_recording: camera.garage does not support record service

This feels like a case of “next time buy an HA compatible camera”. Is this meant to be possible or am I simply wasting my time trying to achieve this using Home Assistant?

Also, I have done the same integration using SmartThings and it has no problem taking picture snapshots.

Is this even possible in HA or am I simply wasting my time?
