Nice. For my old PC setup I built something simpler, using an ATtiny12 =

that would generate a wake-on-LAN or a PCI PME# signal:

It would even provide a signal to tell VDR if the computer was powered =

on by the remote control, or due to some other reason.

With a quick read (ich spreche Deutsch), I did not find a mention of =

systemd or VDR configuration. Can you point to an example?

I think that in any case, I will test my systemd integration scripts on =

an old Thinkpad laptop and a USB DVB-T stick.

I am happy with my current low-tech solution, at least for now. The =

power consumption would be acceptable even if I left the system running =

24=D77, say, if I were away for a week or two. The consumption could be =

reduced further by patching VDR so that it will shut down all tuners =

when it is idle (instead of constantly parsing the EPG).
