Fishermen21 0 Report post Posted June 21, 2018 I bought a 3 gang wifi smart switch wanted to replace one of my existing switches. But when I unscrew the switch and found that the wiring are not the same as the instructions. So I'm confused and unsure how to replace the switch. Any advise?

Pelect 3 Report post Posted June 29, 2018 You need a neutral wire from the light. If you are not familiar it is best to engage an electrician to pull the additional wire and wire up the light switch for you. Not safe to DIY if you are not familiar. Share this post Link to post Share on other sites
