ᐅ Electrical Installation – Retrofitting Switches and Push Buttons Wirelessly

Hello everyone,

before questions about the electrical installation come up: we have deliberately chosen a conventional electrical system.

Now to my question:
Our electrical installation is nearly complete, and I am not sure if all my requests were implemented by the electrician as discussed. He had told me that all light switches would be installed with deep flush-mounted boxes and as push-buttons (at least those that I marked accordingly), so that I can later connect a wireless actuator behind them.

I have now taken a closer look at the switches and found the following types installed:

Merten MEG3115-0000 as a series switch insert (switch function: 2 circuits), rocker push-button
Merten MEG3116-0000 as on/off changeover switch insert (switch function: 2-way), switch
Merten MEG3150-0000 as push-button insert (switch function: 1-way), push-button

As you can see, several types of light switches were installed.
My basic question: Is it possible to install a wireless actuator behind each of these switches without, for example, an off switch position disabling the wireless control?

also the Eltako FD62NP-230V as well. You have to set the operating mode to "phase-cut." Provided you use EnOcean switches.

What does "also" mean here? I was referring to an FL62NP-230V earlier.

1)
If I use conventional switches, can I still dim the lights? I would actually like to keep the conventional switch as it is, but additionally be able to turn the spotlights on/off and dim them remotely via a signal (for example from a logic controller like ioBroker, FHEM, etc.).

2)
If I connect spotlights with their own transformer on the 230 V (230 V) wiring everywhere, can I still dim the spotlights?

You can’t really generalize because it’s not the push buttons themselves but the wiring that matters.

Could you briefly explain how the wiring should be done?

If you want push buttons and prefer a conventional setup, I would do it like this:

Light switch → cable directly to the distribution box.
Light outlet → cable directly to the distribution box.

The installation is already complete. I am basically just about to have it inspected. I would like to check the wiring myself since it is still accessible and the meter has not yet been installed.

Oh, I overlooked that.

There is no single clear answer to this question. However, you need all three conductors at the light switch and the light outlet to be as flexible as possible. Simply put, you should be able to install a socket outlet at that spot as well, which keeps almost all options open. This is just as T_im Norden already described.

Star wiring, basically.
