Fibaro - with what to connect and how to connect two LED lamps without N cable

The way of the community,

Newbie question - it's about the Fibaro system components:

I have this installation: two lamps with LED bulbs (IKEA RYET E26 400 lumen).
They are controlled from a switch in which I have one L wire (input) and two output wires (COM1 and COM2).

I would like to add these lamps to the Fibaro system - but I am wondering how and with what. Because from what I've read, without access to the N, I can only do this using the DIMMER2 - except that this one only has one output - even if I were to connect them together it raises the issue of installing a bypass (on one on both?).

Such an overview drawing: .

Two options:
You get into the junction box where you have N.
You give some kind of after-box radio controller powered by bacteria. As long as it fits you under the switch. However, the latter solution has a disadvantage, because once you have used one you can't control the other unless you use a connection like in a double staircase.

But there is a dedicated FGS 221 switch for this purpose. It works with the Fibaro control panel and switches on two independent channels. And it is still battery-free.

Which doesn't change the fact that there must be N...

In the box leading away from the lamp we have it. The aforementioned switch should be installed there.

Gentlemen,
Thank you very much for your replies. As suggested, I got into the box and changed the cable connection (eliminating one control power supply, gaining N) , both lights are now on one switch - but I gained control in the system.
