auto shutdown

[tezcooling]

Firstly amazing project and thanks to the author and everyone who posted here, I now have an amazing tv!

Not sure if anyone has tackled this, but has anyone set there pi up to shutdown when the HDMI source is switched off?

I was thinking of trying something like:
If all LEDs remain the same colour for 1 minute then shutdown?

Anyone any other suggestions or examples?

Sounds cool, but I fear the VGA signal is rather noisy even if the input
is turned off.

Hmm, well all my LED's go blue when the HDMI source is off, so maybe if I check if all LEDs remain the within a small spectrum of blue for 1 minute then shutdown. I'll start playing with it this week and see where I get.

Anyone else got any smart ideas about how to get it to shutdown automatically?

Actually, the RPI doesn't use that much electricity, so I let it running all the time. (so I also don't have "startup time".
However, I use a separate power supply for the RPI and the LEDstrips. I do power-down my LEDstrips when my TV is off.
(I have a "slave" IR receiver that switches a relais)

best regards,

Kris

Is there a way that the software automatically detects when the input signal is off or does not change over time xy? Like automatically power off function
