For og "unfortunately": It would be nice if the bar would have an output of at least always leads voltage. Then you could also supply the master over the bar with electricity.
As a suggestion I would have to install an adjustable Ausschalteverzögerung. Then my HTPC had time to go down before him the life-giving juice is extracted. So I always have to just shut down the HTPC and can only then turning off the TV (Master).
For the price the thing does but exactly what it should. The star trigger, there was for the missing master socket.
