Electrical installation - Retrofit switches/buttons wirelessly

okay. Now it is like this, my electrician installed switches supposedly to "handover the house functional." With push-buttons, "you have to keep pressing constantly to keep the light on." Since I wanted to install the radio actuators myself, the electrician therefore planned the switches. After handover, I would have to replace the switches with push-buttons + radio actuators... I am really annoyed. This even though I constantly mentioned that we would use radio actuators, even wanted to get them through the electrician – but he said "you can do that yourself later"... I think now I know why...

In your first post, you explicitly wrote that you decided on conventional electrical installations and the electrician delivered exactly that. If nothing else was stated in the contract with the electrician, he did exactly what he was commissioned for.

From my point of view, you approached the matter way too naively. Even if I want to integrate something later, I still check beforehand whether the boundary conditions are right. Especially if the execution has not yet started! The wish should be discussed with the electrician and preferably documented in writing.

In general, I wonder what you expect from the radio actuators? Do you have the appropriate sensors like BM or PM for it, or will it only be the non-smart remote control with the phone?

... or you take something like OPUS directly, i.e. actuator with push button attached. It should save about half the installation time and is similarly priced to the Eltakos. Apart from that, the electrician did everything right here, the comparison with winter tires and rims is quite fitting. What was agreed with the electrician? Did you always just say "we want to retrofit something" or "install push buttons or leave the holes open"? In the first case, the situation is pretty clear.

Why? Push buttons don’t cost 5€ each. You don’t even need a new rocker. It stays the same. I don’t know what kind of place you have, but it won’t cost you more than fifty. If you resell the switches on classifieds or something similar, even less.

Still once more for my understanding: The radio actuator takes over the function of the conventional light switch – so the conventional light switch is only responsible for sending the PRESSED impulse to the actuator?

Yes, if the actuator is defective, nothing works anymore.

What happens if my logic controller is deactivated? How can a light switch still switch the light on/off as a push button? Does the radio actuator then take over that, just directly instead of via radio?

What kind of logic controller? The actuator has an integrated relay that basically “replaces” a switch. If the actuator receives an impulse, the relay pulls in and closes the circuit. A second impulse opens the relay and the circuit is interrupted. Provided everything is connected correctly. By the way, there are also suppliers where you can use switches. Then you can keep them.
