Spotify Chromecast control using a Universal Remote

Chromecasts are not controllable using an IR remote control. This projects adds that function by using a raspberry pi with an IR sensor that receives the remote cotrol codes and converts them into http calls.

Based on https://developers.caffeina.com/reverse-engineering-spotify-and-chromecast-protocols-to-let-my-vocal-assistant-play-music-ada4767efa2

Dependencies:

download and install latest version of spotipy and pychromecast python3 Using sudo easy_install3 ... doesn't work as it retrieves an older version. (why?)

Spotify App

Login to the https://developer.spotify.com and create a new application. Remember client_id, client_secret and redirect_uri.

copy remote.py and config.py to /spotify.google/ (or other folder) then make it executable
update config.py with all the required credentials:

#name of the chromecast device
chromecast = "your_chromecast_name"
chromecast_ip = "x.x.x.x"
volume = 0.8

#spotify_client credentials 
accounts = {"default":{"username":"", "password":""}}

#Application
client_id = "as_created_above"
client_secret = "as_created_above"
redirect_uri = "as_created_above"

give your account a short name and you is later in the login url. ex: accounts = {"john":{"username":"john_spotify@gmail.com", "password":"73847893497389478389479374892398"}} becomes http://127.0.0.1:9999/login/john

The system loggs in to the last used account or to account "default" (if present), if no user is logged in yet. (calling http://127.0.0.1:9999/login is equivalent to calling http://127.0.0.1:9999/login/default if a default user has been provided)

run it once from terminal and follow instructions to activate/authorize Spotify.

Service

create /lib/systemd/system/spotify.service with content:

[Unit]
Description=Spotify Remote
After=network.target auditd.service

[Service]
ExecStart=/usr/bin/python3 /spotify.google/remote.py
ExecReload=/bin/kill -HUP $MAINPID
KillMode=process
Restart=on-failure

[Install]
WantedBy=multi-user.target
Alias=spotify.service

start service

sudo systemctl enable spotify
sudo systemctl start spotify

IR Receiver

The command map file for lirc (/etc/lirc/lircrc):

begin
prog = irexec
button = SPOTIFY_PLAY
config = curl http://127.0.0.1:9999/play
end
begin
prog = irexec
button = SPOTIFY_PAUSE
config = curl http://127.0.0.1:9999/pause
end
begin
prog = irexec
button = SPOTIFY_PREVIOUS
config = curl http://127.0.0.1:9999/previous
end
begin
prog = irexec
button = SPOTIFY_NEXT
config = curl http://127.0.0.1:9999/next
end
begin
prog = irexec
button = SPOTIFY_ON
config = curl http://127.0.0.1:9999/login/john
end
begin
prog = irexec
button = SPOTIFY_OFF
config = curl http://127.0.0.1:9999/off
end
begin
prog = irexec
button = SPOTIFY_REBOOT
config = curl http://127.0.0.1:9999/reboot
end

Where SPOTIFY_* buttons in the lircd.conf file recorded (irrecord --disable-namespace -d /dev/lirc0 /etc/lirc/lircd.conf) or random created codes and then taught to the remote (see https://github.com/MoonshineSG/remote.ir)

Remote control

Setup a new device and a new activity, thne configure the buttons as usual.
