I know I should probably get an electrician, but was wondering how easy it would be to switch my regular switches to smart switches. (After switching off the power naturally)
The current wiring doesnt look like anything I find online. Is it just a case of sticking the 2 black and 1 red into the L1, L2, L3 and then the white into the L?
The electrician who wired my house said there was no neutral wire on the switches.
