Does some kind of wireless light switch exist? (alien.top)

Hey all,

I have a 4 way regular combined light switches on my left, one of which turns on the kitchen light:

The problem is, my kitchen is on the right side of the hallway, so every time I have to go left to turn on the lights.

I would like to put an additional light switch on the right side of the hall, at the entrance to the kitchen, without having to drill the walls and put additional cable.

Is there some kind of wireless light switch paired with something I could put in front of my lightbulb cable that could work in complement to the existing light switch? I don't want wi-fi solutions, it would be stupid not to be able to turn on lights when internet is down.

I'm using everything Hue...

I bought these https://www.philips-hue.com/en-us/p/hue-philips-hue-wall-switch-module/046677571160 (US link because that's in English, but it's widely available in the EU).

And I've put something like this: https://www.into-led.com/en/eco-dim10-zigbee-led-dimmer-module-250w.html near my light. That way I can use Hue and default lights. In another room, I've but Hue lightbulbs, then you don't need the last one.

If I understood this correctly, then I would need to buy smart light bulbs that go with these?

How does the light dimmer work combined with the wall switch?

You can either buy smart lightbulbs or use the Zigbee dimmer. I have the dimmer attached near the light. The wall module says to the Zigbee switch 'go on' or 'go off'.

The issue I have with this is that I'm not sure if it's even possible to install a relay/dimmer behind the light switch in a 4way traditional light switch, as the cables in EU are just "forwarded" in a loop to the next switch

What I've done (I was on mobile so typing was annoying):

- Disconnected the cables from the traditional lightswitch and connected them through. So basically the light would be on at all time.

- The traditional lightswitch is then connected to the Hue Wall Switch module.

- Near the lightfitting itself, I've placed the dimmer-module.

This doesn't have much to do with the way the cables are 'forwarded', since there's always a black wire that should go to the lamp. The others can be looped though, because they're only creating a circuit.
If it's a changeover (multiple switches connected to a single light, like one at the bottom of the stairs and one at the top), you can still just make sure the light is 'always on' and then connect all the connected switches to a Hue Wall Module.
