2 wire to 3 wire system for ZWave
simulate this circuit &ndash; Schematic created using CircuitLab

Figure 1. (a) Your UK ceiling light wiring. (b) What the device requires. (c) A possible solution.

Two options:


Get a neutral down to your switchbox. This is likely to be very difficult.
Mount the Z-wave device in the ceiling near the lamp where you can pick up the neutral.


With option (c) you could short out SW3 and put a blank cover-plate on the wallbox but it leaves you with no way to properly isolate the lamp when changing a bulb other than switching off the circuit-breaker.


  My question, can a 3 wire system be created from a 2 wire system?


No.
