Is there a no-neutral 2-way smart switch?

Hardware

I have a typical 2-way switch circuit for a bunch of lights that I’d like to automate but the ‘main’ switch is mounted in a shallow cavity in a stone wall with a whole load of tight wiring that I really really don’t want to start messing with (shown on the diagram as inhabited by dragons :))

The other end of the circuit is a normal 2-way switch mounted in plasterboard (drywall) which gives me scope to put in a deeper box to accommodate a smart switch or relay module. However, there is no neutral at this end of the circuit.

Does anyone know of a module or switch that is a direct replacement for the 2-way switch? Wifi or Zigbee; not fussed either way.

Must know your geography. Electric component requirements and availability greatly varies by location.

I’m in the UK. 240V AC mains. The lighting circuit in question is on a 6 Amp breaker.

Oh and I didn’t make it clear but I do want to retain the manual switch operation.

I’ve just done this for 15 switches or so, so far. I’ve had to use various methods.

Depends on your wiring tbh

There are many ways to wire 2 way switches depending on the age of your property.

You need to tell us what the demon end is…

Most relays such as the zbminil2 will require a permanent live and a switched live, which you might not have. But do not need neutrals.

The alternative is if you have a ceiling rose with those, to 9put the relay up there.
