I brute forced the IR codes for my Cambridge Audio CXA81 amp, wrote a web server in go that has endpoints to correspond with the actions, wired up a Raspberry Pi Zero W with an IR transmitter, and wrote a Android app as a virtual remote control that connects over WiFi to the webserver on the Raspberry Pi Zero W. I wanted to control my amp from anywhere in my house and Cambridge Audio didn't make that Amp controllable through their app.
