Wifi switch in need of neutral wire - advice on current setup

[Edward Morris]

Hi.

In my lounge, I have 3 single gang switches which control a ring of GU10 downlights. I would like to substitute one the switches for a smart home switch, so that I can turn the lights on and off using a phone app. The model I am interested in is the wifiplug glass +. The literature states that in order for the light switch to remain connected to the wifi, it needs a neutral wire in order to have a constant supply of power. The example wiring diagram from the wifiplug website is shown below.

I have put together a picture to illustrate how the wiring appears to be connected between the three switches. In general it appears to match the diagram from www.lightwiring.co.uk, with the exception that there is no ceiling rose, and the light ring (cables A and B) neutral connections (6,7,8) are contained within the primary light switch back-box. There is also 3 live wires connected to the L1 terminal on the primary light switch, which is the light ring pass through connections (3,4) and the L1 to L2 connection for the second light switch.

My question is pretty simply.
Is it possible to use one of these wifi plug glass+ switches in place of one of the manual switches?
Does the existing setup provide the neutral wire to provide a constant current to the switch?
If the current setup doesn't provide a neutral wire, is there anyway in modifying the current setup to allow for this?

I am not a qualified electrician by any means, and whilst I've learnt quite a lot recently from reading up on the web, some qualified advice would be most welcome regarding these compatibility issues.

Thanks in advance.

I've made a diagram with photos I've taken of the actual switches and the wiring to aid further in diagnosis.
Thanks again.

If you have a neutral in the back box then you should be good to go. Follow the first diagram and forget the diagram showing rose fed lighting.

My advise and experience tells me you should get someone in to do this for you. These device are very sensitive and if wired up wrong the first time can break very easily.
