Free license plate recognition for HA

Free local license plate recognition for Home Assistant — packaged as a copy-paste template (I built this)

Normally, getting plate recognition into HA means stitching together Frigate, a separate AI service, and a bunch of YAML/MQTT automations. Instead, this is one self-contained template you just copy — no extra services to wire up.

After copying, a setup wizard walks you through four steps:

1. Camera — USB/CSI, RTSP, or ONVIF (ONVIF is auto-discovered)
2. HA connection — address/port + a long-lived access token
3. Recognition — Fast vs Accurate mode, and plate region (US / EU / KR)
4. Filter — minimum confidence + hold time. By default a plate has to be read consistently for 3 seconds before it reaches HA, so momentary misreads get filtered out.

Every plate it reads shows up in HA as a "License Plate" sensor entity you can automate off — open the gate for known cars, log entries/exits, alert on unknown plates, and so on.

Quick start

1. Install Grablo — runs on a Pi 4/5, Jetson Nano, Windows, or Mac
2. Hit "Copy to my projects" on the gallery template
3. Open the project, and the wizard launches automatically

There's a phone dashboard for the live feed + recent plates too (needs the Grablo app), and settings stay editable later from an Admin menu.

It's free. Link is in the comments — happy to answer any questions.
