Authorization notice. Vision State is dual-use. Only use it on software, sites and systems you own or have explicit permission to test.

Who it is forA family that wants Home Assistant to know who has arrived, and to notice an unknown person at the door.

The problemPresence sensors often rely on phones, and a camera view of the drive gives no named result.

The outcomeObject and person sensors for COCO objects such as cars, plus named people recognised by face. Unknown people appear as their own sensor.

What you need first

  • Home Assistant OS or Home Assistant Supervised, version 2025.10 or newer
  • The Mosquitto broker app and the MQTT integration in Home Assistant
  • A camera that Home Assistant can see as a camera entity, or an RTSP or HTTP snapshot URL

Steps

  1. Install Vision State, open it from the sidebar, and choose New sensor for the driveway or front door camera.
  2. Draw a region around the driveway or door so only that area is watched.
  3. Choose the objects to watch, such as car, from the list of 80 objects. No training is needed for these.
  4. Turn on face recognition for that camera, then add a few photos of each person and give them a name. Faces are kept in the app's own storage.
  5. Check the object sensor and the person sensor in Home Assistant, then add an automation if you want a message when a named person arrives.

Prompt for your agent

Using the VisionState repo at https://github.com/oleost/VisionState, set up object and person sensors for the camera <camera_entity>, with named people <person_names>. Expected output: an on/off sensor for each named person and for the car object. Verify that face recognition is enabled only for the camera you chose.

Caveat. Face recognition is a dual-use capability, so only enable it for cameras where you have a clear reason and where people have been told they are being recognised.
