[Solved] Light switches in Spain

Hi all,

I’m completly new and I’m trying to build everything. I live in Spain (just in case it’s a relevant thing to say) and I would like to have the light wall switches handled by the smartthings hub

I have both single and double switch, the double ones each switch handles a different cealing lamp.

I have tried to look in the forums, but I don’t get a clear idea of several things:

  • Double light switches, like for instance the TKB TZ66D are not supported due to a hub constraint, so the hub simply doesn’t support any double switches?
  • Can anyone recomend me switches (both double if the first question is wrong, and also single), that are sold/wok in Spain? dimming would be nice but not mandatory

Thank you very much in advance

First, thanks for your reply!!!

It would have to be on top or bellow in the wall, since there is no space “behind” the switch for this.

Any ideas of switch replacement?


Once again, thanks for the reply. I’ve checked and you are correct, it fits! the images of the product are bigger (of course) but it fits.

Just to make sure. Inside there are 3 cables, that’s “ok” for 2 switches right? i saw this image

and seems so, but wanted to make sure

Another question: in one room, I have 2 switches for the same light. Does this work also for this? in which one should I put it?

I see, didn’t know I’d have to rewrite.

My current wires are like this:

(this is actually a 2 button switch for 2 different cealing lamps)

So i guess one is the ground cable and the other two are the electricity ones so I’ll have to rewire like you explained, right?

(like this)

I agree hahahahaha

That double switch controls 2 different lights in the room actually. every one of the 2 buttons is “on/off” for 2 lights in the same room…

I was surprised also, 3 cables 2 lamps, my idea is that 1 could be power into the switch, the other 2 would go to each lamp basically

I guess, before callling an electrician, I’ll do some tests (disconnect one, then the other, etc etc)


I consulted some other forum in Spain and they told me that the device would work great if I got a neutral cable into that box, or I placed the box in the room distribution box (every room has one here), so… thx for all the effort! really appreciate it :). I’ll post a final post confirming as soon as I test it :slight_smile:

Didn’t know about the neutral cable, thanks!

The product seems to work with 3 cables, look at this imagen from the manual (http://manuals.fibaro.com/double-relay-switch/)

Space can be an issue I have to still face. I think it can fit with a bit of tetris, but I can put it con the main room electric cable box

Having said that, on a couple of weeks i’ll share my result, i’ve found that one of my friends actually knows about electric systems in houses, so he’s coming by when the device arrives (21th), so I’ll be able to share the experience :slight_smile:

Just to sumarize, with this schema it’s working as expected :slight_smile:

Watch this YouTube video in Spanish. He explained it well. Sorry if it’s too late
