The HiFi system in my livingroom is centered around an amplifier from the ’80s. There are a few audio sources connected to it: A television A Chromecast Audio A record player The amplifier is powered through a smart plug that, through the power of Home Assistant, turns on whenever there is an active audio source and gets shut when there is none. Although nice and very convenient, this is not enough from keeping the listener from fiddling with the amplifier’s switches to choose the right audio source, since it gets toggled quite often between the TV and the Chromecast.
