Hello,
First of all, thanks for the great project It was easy to set up.
I got my Setup running with a RPi 1 HDMI loop grabber and sk9822 LED Strip.
I use an USB Powersuply for the PI and an ATX Powersuply for the LEDs.
Is it possible to switch the PSU from the Pi. The Hardware part ist clear (Pull "Power ON" on the ATX Connector to GND (via Optocoupler)). But how to detect if there is no input on the HDMI grabber. Effects etc. can be detected via JSON RPC, but even w/o input the hdmi grabber ist present as a priority and its marked as active and visible?
I hope there is a way to solve this via RPC to avoid altering the code.
Greetings from Aachen
