I talked with the electrician about. He seperated these noisy devices (took 
another mains-phase for them. We can install a filter, if that isn't
sufficient.

Yes, this is working exactly like that.
But my switch-on procedure has still problem. Once the dimmer has it's
brightness set, the hardware timer keeps it perfectly stable.
2 hours later... SOLVED, switching per key is working.
Now I need real dimming on long keypresses.... (keyrepeat comes into play)
And to improve my lookup table, so that my brightness ramp gets linear.

If you have some time and energy left, could you connect my node and try to
help debugging?!
I've added comments, so it could be more fun...

Thanks a lot. Working great now. I forgot about them.

How would you switch input function from digital to analog then?
Perhaps the name mask is misleading?

Nice to have, but where you want to use it? My limit is mechanical size - 
i can't connect more wires to the outer world. It won't fit into the wall.
A solution could be integration of the 1wire net. At work I develop a
1wire net with DS1820 to measure 20temps all over a production hall. If
we could have a gateway, we also can more inputs at different locations in
the room and so on. Code examples for avr are available, but I can't integrate
them.

There always will be limits... time is mine at the moment...
