@jjok you might find some interesting ways to plug bluetooth input with mopidy commands by using Node-RED https://nodered.org/
- bluetooth flows : https://flows.nodered.org/search?term=bluetooth (if you’re using a bluetooth enabled pi it’s even easier)
- command with https://flows.nodered.org/node/node-red-contrib-mopidy
I’ve managed to interconnect lircd and mopidy easily with this type of approach (see Controlling mopidy with lircd and Node-RED, screen with android tablet )
