What is switchable for everything? Well, to switch the devices... who needs a million clocks etc.? And everything consumes power all the time when it is plugged in... sure, it’s only half a watt here, two to three watts there... but with 5, 6, 7 devices, that already adds up to 20 watts... I’d rather save that by switching off the devices when not in use and thereby operate my bus power supply, because that has to run 24/7... and in "normal" houses you can also save yourself this unnecessary consumption...
With me, the sockets are switchable in any combinations or individually... for example:
- everything goes off when we leave the house
- the Christmas lights automatically come on in the evening and at some point during the night turn off again
- the TV, SAT, 5.1 all turn on together when you want to watch TV
- or the TV turns off and the projector, SAT, 5.1, Blu-ray turn on when you want to watch on the screen
And so on and so forth. Each time, only what you need is on and the other devices are disconnected from the power grid...
