So not sure if anyone can help with the small amount of information I have but I have a 3 way circuit (same light but 3 switches
Switch A
Switch B 2 gang but the one closest to my thumb is the switch that controls the circuit I need
Switch C 2 gang but the one closest to my thumb is the switch that controls the circuit I need
I can't figure out where I would wire the shelly 1L
Any help would be greatly appreciated
