Smart home with Eltako wireless actuators

PN doesn't work yet because of the number of posts.

I would like to be able to dim lamps later on.

It is important for us that we can still operate the switches/buttons as before but also retrofit them later via radio, so there is enough installation space for radio actuators and protocols that also allow remote switching via radio - even if the lamp has been manually switched off using the switch.

That works with pretty much all radio actuators. I already wrote about the space before.
