Frigate storage usage sensor

Configuration
1

Frigate integration creates whole bunch of sensors, but I missed storage usage sensors.
In case somebody else need the same here are how I did.
Frigate published MQTT topic: frigate/stats and data is JSON:

Interesting was last section, “service”:
It was little bit tricky to extract values which I needed because of slashes in JSON dictionary names, but there are my sensors:

mqtt:
  sensor:
    - name: "frigate_storage_free_recordings"
      unique_id: "frigate_storage_free_recordings"
      state_topic: "frigate/stats"
      value_template: "{{ value_json.service['storage']['/media/frigate/recordings']['free'] / value_json.service['storage']['/media/frigate/recordings']['total'] * 100 }}"
      unit_of_measurement: '%'
      icon: mdi:database

    - name: "frigate_storage_free_clips"
      unique_id: "frigate_storage_free_clips"
      state_topic: "frigate/stats"
      value_template: "{{ value_json.service['storage']['/media/frigate/clips']['free'] / value_json.service['storage']['/media/frigate/clips']['total'] * 100 }}"
      unit_of_measurement: '%'
      icon: mdi:database

    - name: "frigate_storage_free_cache"
      unique_id: "frigate_storage_free_cache"
      state_topic: "frigate/stats"
      value_template: "{{ value_json.service['storage']['/tmp/cache']['free'] / value_json.service['storage']['/tmp/cache']['total'] * 100 }}"
      unit_of_measurement: '%'
      icon: mdi:database

    - name: "frigate_storage_shm"
      unique_id: "frigate_storage_free_shm"
      state_topic: "frigate/stats"
      value_template: "{{ value_json.service['storage']['/dev/shm']['free'] / value_json.service['storage']['/dev/shm']['total'] * 100 }}"
      unit_of_measurement: '%'
      icon: mdi:database

Hope that I helped somebody…

How would you create a GPU sensor?

I tried:

- sensor:
    name: "GPU - intel-vaapi"
    state_topic: "frigate/stats"
    value_template: "{{ value_json.service['gpu_usages']['intel-vaapi']['gpu'] }}

- sensor:
    name: "GPU - intel-vaapi"
    state_topic: "frigate/stats"
    value_template: "{{ value_json.gpu_usages.intel-vaapi.gpu }}"

didn’t work

I did!

- sensor:
    name: "GPU - intel-vaapi"
    state_topic: "frigate/stats"
    value_template: "{{ value_json.gpu_usages['intel-vaapi'].gpu }}"

Can you explain this with a little more detail on where this goes? I would like to see all this in home assistant.

This is what i need to detect the NAS storage is successfully connected. Because i had some issues, and Frigate start to use the internal storage, because when it started, the external storage was not available. And some days later i was shocked, when the internal ssd was full.
Thank you very much!
BR,
Zsolt
