Is it possible to pull an extra neutral wire from one of the lights to the switch?

Then it should be possible to use a walli switch.

Have a look if you buy or borrow something like this.

I wouldn't pull out the wire witout being sure that you can replace it with 2 new ones. Otherwise you will maybe end up wihout lights

 

If Iook at the walli switch drawings they al need a Neutral, so I assume they will not work without a neutral.

Even if you would place a Fibaro switch in light itself you will have to pull a Live wire to the lights.

Fibaro Dimmer 2 doesn't require a neutral. Have a look at the manual at diagram number one. https://manuals.fibaro.com/dimmer-2/

 

You will need 1 dimmer device per switch. Also 1 fibaro bypass per switch if the load is below 50W. Not sure how big your switch box is, but you can also locate these items at the light itself.

Thats correct,

I assume @terryble66 was  talking about a switch (FGWDSEU-221), he could consider to use a dimmer (FGWDEU-111 ).He has to make sure that his lights are dimmable.

The Dimmer 2 works with non-dimmable loads. The calibration process will detect whether dimmable or not, and control accordingly. I have non dimmable CFLs working in on/off mode while I wait for some fancy dimmable LEDS to arrive. However, I do have a neutral to that dimmer.

 

Are you saying that to operate without the neutral, bulbs must be dimmable?

Nope, I'm cannot really confirm that.

 

The only thing I experienced was that I hooked up a non dimmable light to a Fibaro dimmer and it gave me a lot of headache.
With and without neutral, Lights not completely Off, flickering, not possible to switch Off at all.

This till a replaced the Light source. If you search the forum for the dimmer you find a lot off satisfied people but also many who are struggling.

So that's why a said, make sure that you're lights are dimmable, in that way you have none or less issue's.

Certainly I agree that there are compatibility issues between some types of bulbs and the dimmer, so yes best to use dimmable ones.

 

I think the way the Dimmer 2 works without a neutral is that the small current it uses to power itself must then pass through the load. This current is sometimes enough to cause the bulb to glow.

 

Given the fibaro switch can not allow this small current (as the load is either fully on or fully off), that is why the fibaro switch must have a neutral connected to the device.

 

Dimmer 2 is a good product that allows you to get around not having a neutral.
