Wife's restaurant has a speaker system that is powered by a AV amp connected to a desktop PC in the upstairs office. I'm looking for a solution where I can easily remotely turn on/off music from the AV receiver or desktop pc. A bonus would be to remotely turn off the power on the AV at night as well.

Prior idea was to use Teamviewer (from mobile app) to remote into the desktop in office and put a timer to the electrical outlet for the AV.
