Hi Roberto,
Hi Mark
Prety much anything that supports GPIO or configurable LED's should be able to do what you want with a little bit of hardware hacking. My preferred method would be to de-solder an LED and replace it with an optocoupler. Interface the optocoupler to your control circuit.
Well, honestly I have no experience at all on hardware hacking. Are you aware of some web resource that provided some kind of schematics?
To find out what hardware has accessible LED's get a listing of the kernel modules with "led" in their names off the download pages for the various architectures.
I assume that you suggest to use the led on/off function to power up/down the device, right? This is partially useful, however this assumes that the device didn't crashed. The problem is that I have some device spread around several floors and it is annoying to reboot them one by one when this is required. That's why I was looking for some POE device with a remote switch and then I've thought that it could be useful to have some kind of power consumption reading.
