[OpenALPR](http://www.openalpr.com/) integration for Home Assistant allows you to process licences plates from a camera. You can use them to open a garage door or trigger any other [automation](https://home-assistant.io/components/automation/).
|
|
|
|
### {% linkable_title Local installation %}
|
|
|
|
If you want process all data locally, you need version 2.3.1 or higher of the `alpr` commandline tool.
|
|
|
|
If you don't find binaries for your distribution you can compile from source. Documention of how to build openalpr is found [here](https://github.com/openalpr/openalpr/wiki).
|
|
|
|
On a Debian system you can use this `cmake` command to build only the command line tool:
|
|
|
|
```bash
|
|
$ cmake -DWITH_TEST=FALSE -DWITH_BINDING_JAVA=FALSE --DWITH_BINDING_PYTHON=FALSE --DWITH_BINDING_GO=FALSE -DWITH_DAEMON=FALSE -DCMAKE_INSTALL_PREFIX:PATH=/usr ..
|
|
```
|
|
|
|
Verify your `alpr` installation with:
|
|
|
|
```
|
|
$ wget -O- -q http://plates.openalpr.com/h786poj.jpg | alpr -
|
|
```
|
