Integration with Home Assistant

See the Home Assistant documentation of the LIRC component to have a more details. If you wont that Home Assistant recognize the press of a specific button of your remote, you have to add the button and the remote name in the .lircrc file located in /home/homeassistant/.
The .lircrc file is accessible via samba.

See this example of entry in the .lircrc file:

/home/homeassistant/.lircrc
begin
    remote = SONY
    button = KEY_1
    prog   = home-assistant
    config = see-this
end

Add an entry for every button that you wont to be recognized. The button can be associated later to an automation.

The values you set for the field “button” must be the same as in the lircd.conf file as well as the “remote” name.

The values you put in the “config” field will be the sensor value in Home Assistant when you press the button.

Restart lirc to load the changes.

pi@d-diot:~ $ sudo systemctl restart lircd

Test your LIRC installation before proceeding by running:

pi@d-diot:~ $ sudo -u homeassistant -H -s
homeassistant@d-diot:/home/pi $ ircat home-assistant

At every press of KEY_1 in the SONY remote a line should appear. Switch back to user “pi” and restart Home Assistant

homeassistant@d-diot:/home/pi $ exit
pi@d-diot:~ $ sudo systemctl restart home-assistant@homeassistant

Now every time you press a button defined in the .lircrc, the LIRC component fires ir_command_received events on the bus. You can capture the events and respond to them in an automation script. See the LIRC component documentation to learn more.

If you wont to send an IR command directly from Home Assistant, that is useful when you are on a remote connection where the lirc_web interface is not accessible, you can use the built in RESTful API of lirc_web.

To do this you have to configure the RESTful Command component of Home Assistant. For every remote key add an entry in the configuration.yaml as in the example below: <file yaml
