I guess my previous posting made me look like a slob.
So for my exoneration, here’s my TV ‘micro site’.
It’s a classic electrical wiring case/hub with a Pi and a couple of zwave actuators to control rollershutters, spotlights and the TV cover plate (it’s powered by another rollershutter).
The shelf below the TV can be removed to access the Ethernet switch, HDMI and audio cable works.
That’s the AVR to the left.
