Anyone know of multi way zigbee dimmer hardware?

Hi there - I’ve been looking for ages but can’t find hardware that will do what I want, though it seems like a common use case so I’m sure there must be something out there.

Does anyone know of a zigbee comparable dimmer that will work in a multiway setup and ideally with neutral only. So what I need to achieve is the following. This is a for a UK lighting system

  1. I have a multiway light setup for the landing lights - there are three points the lights can be turned on/off from (this is using what is sometimes called a traveller system but is pretty much UK standard) e.g. the switches at the end are 2 -way and the one in the middle is multi way (aka intermediate).
  2. The switches at the end are MK grid setups i.e. they are 2 and 3 gang with other circuits attached. The intermediate is a 1 gang.
  3. I want to add a dimmer to this system - it’s probably easiest if it replaces the 1 gang multi way. Ideally this would be a real rotary dimmer but I could just use a unit that hides in the back box and is controlled remotely.

Does this exist? I can’t find a zigbee 1 gang multi way rotary dimmer anywhere - I tired the candeo dimmer which said it was multiway but it only works with momentary switches while I have rockers. Help! I’d take other creative solutions too - I just want to use HA to zigbee dim the lights at night.

Can you modify it as momentary switch or just replace it?

Thanks! Yeh I guess I could replace the other two switch with instantaneous switches - though I was kind of hoping to do it without changing too many other fittings! (my partner already thinks I’ve spent too much time messing with HA and making things “more complicated”. It’s a good back up though.

NB it’s the small UK switches that I’m dealing with so they aren’t easy to modify
