LIRC Setup for Openhab2 on the pi

#1

Hi guys. Here are instructions for controlling IR appliances.

Materials:

IR LED (940nm)
IR receiver
Wires to connect the IR LED
Breadboard or Protoboard
Your openHAB setup

  1. Follow the instructions here to setup LIRC on your Raspberry Pi.
  2. In PaperUI, open the Bindings tab in extensions, and install the LIRC binding.
  3. SSH into your Pi.
  4. Open /etc/rc.local with an editor, and add
    killall lircd
    lircd --listen=9001
    before the line that says exit 0.
  5. In paperUI, add an item from the LIRC binding (manually).
    a. For the host, put localhost if you are using lirc on the openhab pi, or the other linux device’s hostname.
    b. For the port put 9001

If you have already added remotes with irrecord, then they should automatically show up. Here are a few of my LIRC configs which you can add to the end of lircd.conf in /etc/lirc

# conditioners look like they have very similar controls, so I would guess this 
# will work for all.  It will probably also work for the Heat/Cool wall models,
# other than the missing heat button, but I haven't tried that.

This is awesome! Gotta give it a try sometime during summer. Also, will any IR LED work as long as it’s 940nm?

#3

Yes. It should work.
