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

After a day of research, I decided to order this ZigBee Thermostat:

Thank you for the response, I’ll check this out in more detail

Thank you for the detailed response, much appreciated!

After reading several other responses, I came to the conclusion that using things via ZigBee might be the best option in the long run, so I can modularly build everything without having to rely on a single vendor.

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?

any ZigBee options that pop to your mind?

the cleanest option at the moment seems like installing a relay behind the manual switch which can be paired with a wireless remote switch

Thanks for the recommendation!

I looked at the products, which one did you get?

I wonder why didn’t they put pictures where the small relay goes… did the electrician connect it behind the manual switch or?

Not sure I fully grasp how this works

There are two types of lights in my kitchen, led lights near the wall and strong LED’s over the kitchen island - we usually turn them on when cooking, it wouldn’t be great if those were motion turned as it’s too strong. But thanks for the idea!

but then I would have to buy a Smart light which is connected to this module?

what’s an extractor? how to pair the wireless switch so it works in complement with the kinetic switches? (eg. if I turn on one or the other, the lights turn on, if I turn off one or the other, the lights turn off)

I didn’t think this would matter, so I pasted some random light switches I found on the internet just so people get the idea as I don’t know how exactly it’s called.

Would you mind linking your example so I can investigate into more detail?

Would it somehow be compatible with the existing “traditional” switch, so both can be used at the same time?

In some other sub, someone suggested me a relay behind the main switch and a wireless ZigBee button, so far it sounds like the best option. Would this be similar in any way?

ZigBee would be ideal, I’m planning to build a HA solution in the future, but this and a thermostat are the first step.

Do you have an example I could investigate? I’m based in the EU.

That sounds interesting, could you send an example so I can investigate?
