Guys
Just wanting some quick validation here. I have another somewhat annoying wiring situation in my garage. I have an old school 3-way setup, with the primary switch location having the 14/2 line input and 14/3 output at the front of the garage. We NEVER use this switch.
At the other end of the garage, I have the location 2 switch where we enter the house. This only has a single 14/3 cable with nothing else close by.
I think it's wired with the classic light in the middle scenario like Diag. 1, though I will definitely head up into the garage loft to check that before proceeding.
I am going to replace the location 2 switch with a GE26931 Z+ Motion Switch, which typically wires the same as the HS switches and other GE switches. I can't replace the location 1 switch as that is frequently obscured and it won't trip on the motion sensor. To implement the 3-way with the new switch I would need 4 conductors + ground at location 2 and I don't have that.
My thinking therefore is to remove the location 1 switch entirely and let the motion sensor do it's job from location 2. That means I don't need a traveller and I should be able to re-jig the existing wiring so that I have line/load/neutral at location 2.
Diag. 2 shows what I think I need to do. I will flip the red/black in real life - the diagram was easier to modify this way!
Of course, I may find that this is wired completely differently when I get to the light fittings, but if not, any thoughts on this solution?
Cheers
