Anyone know how I wire this in please? 2 gang switch. The one on the right is the one I want to add it to
Sorry but your switch looks incredibly straight forward. Top is common (live). Bottom is switched live. Your blue cable is neutral.
What else do you need?
Worth noting your back box looks very shallow not sure how you think the module will fit.
As we always say on this forum, if you don’t feel confident you know exactly what you’re doing please get a professional in.
