So I'm in the process of adding a smart switch to my exterior lights which is on a gfci protected circuit. With the way the house is currently wired the lights are wired upstream of the gfci(which I added before)
The issue is I believe is the neutral wire is after the lights connected to the line side of the gfci causing a voltage difference tripping the gfci. I've confirmed this is the case because the gfci only trips when the lights are turned on and by bypassing the current neutral wiring and connecting a new neutral wire from the light(white wire) to the load side neutral wire. This works.
It's not convenient to run another neutral wire back the the load side of the gfci so I'm thinking if I replace the breaker with the gfci everything will be downstream on the load side and it should work.
Does this sound like a reasonable plan?
Edit: would this configuration work? I realize I should have made the lines coming from the switch to the lights red(hot)
