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?

You cannot make a general statement about this because it is not the switches themselves, but the wiring that is decisive.

You can always set up the push-button function with a remote control in the distribution board. There is a wide range of products available, for example from eltako.

From the distribution board, the supply lines branch off to the individual rooms. From there, they go to the light switches.

I have already discussed the Eltako EnOcean switches with the electrician. For cost reasons, I will order and install them myself.

Due to my professional background (our company manufactures EnOcean sensors, actuators, and gateways), I can only recommend keeping an eye on the wireless range! Test it in advance before you get frustrated!
The average range inside a building is 15–30 meters (50–100 feet).

I wanted to order the wireless actuators now, but I'm stuck here:
My electrician recommended the model "FL62-230V" for switches to lamps. However, there is also the "FL62NP-230V." NP stands for potential-free (no voltage). Should I choose the NP version?
