There are so many companies that I am sure countless individuals have come along and have solved a problem for themselves that many other customers probably have. These solutions hardly ever surface.
I for one was upset when I bought a HiFi amp from Cambridge Audio (CXA-81) and it came with an IR controller. The only way to be able to control that amp through the app is by means of a DAC which costs another couple of thousand dollars. I refused to accept this as my solution. I wrote a web server that used a Raspberry Pi Zero W and an IR transmitter along with a rudimentary Android app that had a series of buttons which corresponded to the functionalities I needed.

If anyone is interested the web server (written in Go) that the Android app talks to is located here https://github.com/ozfive/CXA81-IR-Remote-Server
I will upload the the Android app source in the next week.
