I'm in the UK and I'm trying to fit a Smart 2-gang switch to control outdoor lights. I looked at the back of the existing switch and saw a black wire I assumed to be a neutral wire. So I bought a 'neutral switch'. I'm not sure now. You can see a photo of the existing switch connections and the Sonoff WiFi
Do I in fact need a switch with no neutral?
Many thanks in advance.

- TL;DR
- Has my existing light switch got a neutral wire or not?
