IR remote control for Raspberry Pi

PiIR

IR remote control for Raspberry Pi.

PiIR is a client program for pigpio, the excellent hardware-timed GPIO library. Some code are taken from its sample program irrp.py.

Features

• Records and plays IR remote control code.
• Decodes and encodes NEC, Sony, RC5, RC6, AEHA, Mitsubishi, Sharp and Nokia formats.
• Dumps decoded and prettified data to help you analyze your air conditioner's remote.
• Both command-line and programatic control.

Requirements

• Raspberry Pi (any model where pigpio works should work)
• IR LED and/or receiver on GPIO (see Hardware section)
• Python >= 3.6
• Running pigpiod daemon

Installation

sudo pip3 install git+https://github.com/ts1/PiIR.git

Start pigpio daemon.

sudo systemctl enable pigpiod
sudo systemctl start pigpiod

Command line usage

piir record -g GPIO -f FILE

This asks key names on your remote and to press the keys. The resulted data is saved to FILE.

piir play -g GPIO -f FILE KEY

This sends IR signal for KEY from FILE.

piir dump -g GPIO

This prints decoded data of received code.

For more options try -h.

API

To send an IR signal recorded in a file:

import piir

remote = piir.Remote('FILE', GPIO)
remote.send('KEY')

Hardware

I'm using Raspberry Pi Zero WH with four IR LEDs. Each LED has a measured current of 120mA, switched by a transitor connected to GPIO 17.

Also onboard is a 38KHz IR receiver from Sharp, connected to GPIO 22.

Unrelated, but the big gold one is a CO2 sensor.
