Simplest Battery-Powered Wireless Light Switch for Multiple Receivers?

Hi, to be honest it's a bit silly to ask but I'm looking for the simplest system based on wireless light switches (in the sense of a battery powered one or two button switch) that can be paired with receivers (one or more).

I started reading and usually there is a firing up of entire Smart Home ecosystems with sensors, touch switches integrated with apps etc.

I for a change am a simple man and am simply looking for a battery-powered wireless switch that I can pair with one or two receivers in a room.

Example:
In the living room I have one switch by the door and a ceiling lamp in the middle of the room.
I thought I would like to be able to run two other lamps in addition (in two corners of the room).

My cunning plan is to remove the current single-circuit switch, bridging the wires and installing a battery-operated wireless two-key switch in its place.
To one key I would like to have a paired receiver at the ceiling lamp and to the other two receivers (lamps in the corners of the room).

Now the question is what to choose. It would be nice to be able to connect these receivers to my home Wi-Fi and control them from my mobile app, but this is not the most important criterion. There are full of different kits both on Allegro and AliExpress and to be honest I don't know which way to go, also I would ask for advice.

If the topic is not smart enough, then I apologise and will be happy to start it somewhere else.

Greetings!

I, for one, am against connecting everything possible to the internet. But that's me.
At home I use a wireless switch from IKEA offer, dimming etc.
Switch approx. 60 PLN, 30W driver for LEDs approx. 150 PLN, 24V leds are best built to your own liking (recommended) or bought from IKEA (not recommended, because expensive as...).

Start by verifying the electrical installation. The receivers require a power supply. That is to say, you must have two L and N wires available where they are installed. In the case of lighting, it is not always possible to find such a place.

In terms of the light source itself, it will probably be typical 12V led strips plus switching power supplies for them, but that probably doesn't matter because I don't need to have a dimming option.

I am curious, however, about the need to verify the electrical installation. I'm a little unclear about this. I'd like to point out that I'm not familiar with it, but I always thought that in order for an AC receiver (here a light bulb) to work, you need to have L and N wires and on one of them (L) there should be a switch. Is there any other way?

allegro is faster than aliexpress (I also think more trusted). A switch (if you are not going to redo the current one) https://www.smd-led.pl/wlacznik-swiatla-na-baterie-tuya-zigbee-2kan-zls2s-46968

A normal mechanical switch can be on the L wire. The WiFi receiver you are thinking of needs to be permanently powered. Where you want to mount it therefore needs L and N wires. The most natural place is the junction box of the original light switch. However, the N wire is not normally connected to this box. You will need to find another place to mount it and, depending on how the installation is laid out, this may require chiselling the wall.

Hmm, but I want to place the switching device for the ceiling lamp (to my mind the receiver) at the lamp itself, not in the contact box. Unless I'm still not catching something....

If the receiver fits on the ceiling and you connect the wires of the original switch, it will be OK.
