I don’t have the skills to write a proper full integration for my Pioneer Amp, hopefully someone will pick it up in the future.
In the interim, I have used the excellent integration from @kennymc.c to send IP commands using the eISCP protocol supported by the Amp: GitHub - kennymc-c/ucr2-integration-requests: A network multi tool integration for Unfolded Circle remote devices
See my post on how I did it here: Discord
Hopefully others may find this useful.
