Dimmer 2 in double switch configuration controlling only the other light

[TLFIN 0]

I have situation where there is a double switch, controlling 2 separate lights. And by double switch I mean one single switch on wall that has 2 stationary switches. There is one incoming Live wire and 2 outgoing to the lights.

 

Question is that is it possible to have such configuration that the dimmer would be used together with this switch for one of the 2 lights?

 

I have found similar issue being discussed on a forum, here:

It appears that users on that forum have changed their wall switch, but in my case that is not an option.

 

So the question is that is the attached wiring a proper solution.

Unfortunately no you can't. S1 is not intended to supply power for a load.

Of course there is one option. Not according to your scheme. If you do not require the switching of the non-dimmable circuit by the Fibaro module, but only by a second separate switch, you can connect it.

But it must not pass through the Fibaro module. That's a pure electrician. The assumption is that you connect the direct phase L to one terminal of the switch and from the other terminal of the switch to the light. Classics.

Then connect the second light according to the instructions for the dimmer.

You will therefore need two separate spins (1+1 or 6+6) in one machine. I'm also doing a button + power off combination

Yes, the other light does not need to be operated at all by Fibardo module.

It would be simple if the switch was a modern version.  But the switch I have is from 1940s and has only 3 pins/connectors (Live in and 2 out). I have not been able to source something similar look modern that would have more pins. Maybe the correct term would be 1+1 swich or 6+6, not sure.

So you only have two options.

Change the switch to 1+1 (or 6+6), or abandon the idea of dimming and you can use the Fibaro module with a double relay or double switch - so you can even control two lights independently (only on/off).

These modules can be controlled by the attached phase.

I assume you have type 5 (1x IN can be switched to 2x OUT in various combinations).

Send a photo of the disconnection, we need to find something.

There are many manufacturers and there is no harm in making a change if you are no longer close to the original. I'm from the Czech Republic and I ordered the plugs/switches originally from Spain.

Yes, the type 5 kind of a switch. Looks externally something like this:

And it is partially embedded to the wooden panels around it, so if I was to change the switch, it would need to be round and close the same diameter as the old one (about 85 mm).

I think I will search for options with those dimmable light bulbs. This is light is so that it affect our movie experience, would be good to have the light dimmable.

 

Maybe one option would be that I make this light dimmable and usable only via smarthome systems. So that there is no usable mechanical switch available at all. There is no emergency kind of things related to this light so that mechanical switch would be needed.

Hello.

I see that it is porcelain's design.

ABB makes the Decento range. You might like it.

You can use 2 buttons in connection 1/0+1/0

You use one switch as a button and with the other one, which will be directly on the light, you can pull out the spring and make it a switch

 

or two switches in a 6+6 connection.

If you look around the country, you will definitely find a supplier of your origin

al design.

Alternative..6+6

Thanks. The last one (Renova) I know. I have those in some other rooms. It has rather plastic feeling to it, but still a lot better option to me than most of the stuff available on the market.

 

Anyways, I am now leaning towards the solution of using a smart light bulb that would be dimmable via Homeassistant.  The lamp  itself is such design that the bulb will not be visible, so it will not ruin my "1940s feeling"...
