I think you'd be very lucky for it to fit in a 35mm box, but it may depend upon how far back your light switch units project into the back box. I tried a couple of different makes and they differed quite a bit as to how chunky they were.
I did manage to connect one to a 35mm back box as I recall, but only by letting the dimmer dangle down the wall recess behind the box.

I put mine in the light fixture in the ceiling mate. My back boxes are tiny and chipping out block was too much hassle. I found the ceiling to be 1000 times easier to work with and produced the same result.

It depends on the depth of your switch! In the retractive switch market the Minigrid switches seem to be the shallowest, but there are switches that would barely fit in a 35mm box without the dimmer unit (Legrand Arteor). It also depends how many cables you have to deal with. I would recommend sizing it up with a box beforehand, you may squeeze it in if you are lucky.

There are two parts to the answer - the depth of the back box, and the depth of the switch plate.
As as extreme example, it is possible to fit a FGS212 into a 25mm back box but this needs a shallow switch, like a MK 1-Module grid frame and 'intermediate' (translation - push) switch with packing to stand the front plate forwards by 2mm. The grid system plate is slightly shallower than others, giving more room in the box.
Just be careful of crushing the contents when screwing up the plate, and watch the Z-Wave aerial - it is at mains voltage with thin insulation that can get damaged.

Just to add - I did buy this and it did fit inside a 35mm box fairly easily. That said, the box only had 3 wires going into it and the front plate did not intrude far into the box either; I can easily imagine it won't fit so easily in some other 35mm boxes.
I then also found that some other boxes in my house are only 25mm... no chance!

Was it the v2 which you installed? I've found the guide to install in the ceiling but the guide specifically says for v1 only?

Hey Matty, yes, all functioning fine. On Fibaro's site I don't see it say "v1 only" on the schematic. Technically wiring it into the ceiling is no different than behind the switch. In a 2 wire system, you have live run to the switch from the ceiling ring, and a switched live back from the switch to the light. I found it easier to install in the ceiling as you can wire it like the 3 wire schematics since you have neutral there.

Thanks. All working fine. It was actually the one on here which says v1 only.
