Lirc seems a lot easier to set up with Buster - if you are using it to control Mopidy it's a doddle to set up.
Set up is assuming you have set up Mopidy on a Raspberry Pi with Buster, you will also need to have installed mpc (sudo apt install mpc)
First of all you need to get your IR receiver, the kit here is what I've used.
To connect up to the GPIO pins there are lots of images here, I used pin 2 for 5v power, pin 6 for Ground and pin 12 (GPIO 18) for data/input. You can choose whichever pins suit, but remember which one you use for the data/input as you'll need to enter it in the conf later.
If using a similar receiver to the one in the link, the wiring is as follows, with the X on the receiver facing away from you;
Pin 1 is Ground, Pin 2 is Power and Pin 3 is Data/input.
If you have a lot of info etc on the sd card I would recommend backing up the card.
Once you have the hardware in place and if relevant you've backed up the sd card.
Start here, ssh or open a terminal window, then;
sudo nano /boot/config.txt
Scroll down to this line, remove the # and enter the gpio pin number.
# Uncomment this to enable infrared communication.
dtoverlay=gpio-ir,gpio_pin=18
#dtoverlay=gpio-ir-tx,gpio_pin=17
ctrl x to save and close
sudo reboot
Once it's restarted
sudo apt update
sudo apt install lirc
Installation might fail on Buster here because of the .dist suffix, if so the following will help, then run the install lirc again.
sudo cp /etc/lirc/lirc_options.conf.dist /etc/lirc/lirc_options.conf
sudo apt install lirc
Once installed, open,
sudo nano /etc/lirc/lirc_options.conf
and change the following lines
driver = default
device = /dev/lirc0
ctrl + x to save and exit.
Now to set up the remote config files with the scan codes;
sudo nano ~/lircd.conf
If you are using the Keyes or similar remote you can try the codes below - if not you can either use irrecord to record your own, search sourceforge for similar brand or search google.

Now replace the original lircd.conf with the new one;
sudo cp ~/lircd.conf /etc/lirc/lircd.conf
and reboot
sudo reboot
Now test the remote by using irw, type irw at the command prompt, then point and press remote buttons, with a bit of luck you'll get something similar to this.
ctrl + c to exit irw
Hopefully you've produced a similar result to the screenshot above.
Now to instruct what each button will do, if you use my existing file as a temp measure then adapt to your own needs using mpc, you will also need to run irexec. Open a new file;
sudo nano /home/pi/.lircrc
and paste in the following
-----------------------------------
begin
prog = irexec
button = KEY_PAUSE
config = mpc toggle
end
begin
prog = irexec
button = KEY_NEXTSONG
config = mpc next
end
begin
prog = irexec
button = KEY_PREVIOUSSONG
config = mpc prev
end
begin
prog = irexec
button = KEY_NUMERIC_POUND
config = shutdown –h now
end
begin
prog = irexec
button = KEY_SHUFFLE
config = mpc shuffle
end
begin
prog = irexec
button = KEY_VOLUMEUP
config = mpc volume +10
end
begin
prog = irexec
button = KEY_VOLUMEDOWN
config = mpc volume -10
end
# insert your playlist name between the " "
begin
prog = irexec
button = KEY_1
config = mpc stop; mpc clear; mpc load "Your playlist here";mpc play;
end
# insert your playlist name between the " "
begin
prog = irexec
button = KEY_2
config = mpc stop; mpc clear; mpc load "Your playlist here";mpc play;
end
begin
prog = irexec
button = KEY_3
config = mpc stop; mpc clear; mpc load "Your playlist here";mpc play;
end
begin
prog = irexec
button = KEY_4
config = mpc stop; mpc clear; mpc load "Your playlist here";mpc play;
end
begin
prog = irexec
button = KEY_5
config = mpc stop; mpc clear; mpc load "Your playlist here";mpc play;
end
begin
prog = irexec
button = KEY_6
config = mpc stop; mpc clear; mpc load "Your playlist here";mpc play;
end
begin
prog = irexec
button = KEY_7
config = mpc stop; mpc clear; mpc load "Your playlist here";mpc play;
end
begin
prog = irexec
button = KEY_8
config = mpc stop; mpc clear; mpc load "Your playlist here";mpc play;
end
begin
prog = irexec
button = KEY_9
config = mpc stop; mpc clear; mpc load "Your playlist here";mpc play;
end
begin
prog = irexec
button = KEY_0
config = mpc stop; mpc clear; mpc load "Your playlist here";mpc play;
end---------------------------
ctrl + x and y to save and exit
Need to make sure irexec starts on reboot, easiest way I found was to add it to cron
sudo crontab -e
scroll to the bottom and add
irexec
ctrl + x then y to save and exit
Reboot
When it comes back up, open your chosen web client for mopidy, start a track playing then try and control it using the remote. Good luck
