Today's video is a follow on from my previous video where we took a look at using Shelly smart relays to control smart bulbs. However, in this video we'll be focussing on how to implement the same setup, but where you don't have neutrals behind your light switches. In the UK, these lighting circuits are referred to as using the "3-Plate Method". We'l. take a look at two different options, first of all using the purpose made Shelly 1L Gen3 behind the light switch, and then we'll take a look at a second option using a regular Shelly device, but installing it behind the light fitting where we do have a neutral!
