Hello - I’ve read a lot on this forum over the years to get help (thank you) but this is my first post. I have a new construction home where I am installing smart switches. I took more than 30 out of the old home and brought them with me, so I’m familiar with wiring and getting things to work.
One 3-way switch that controls patio LED lights (attached to fans, separate switch) does not have a neutral in the box. The other does. I plan on getting the electrician out to run a neutral to the box under warranty, but I do have things temporarily working.
I have a GE Smart Dimmer on one box (which I believe is the auxiliary based on the pictures), and the other (I believe is the master) I left alone with the original switch since there is no neutral. If the dumb switch is on, I can operate the smart switch normally. If the dumb switch is off, the smart switch has no power. This is ok with me as I plan on using a door sensor to operate the lights anyway.
I’m only allowed one pictures, so I showed the wiring for where I put the smart switch. Note the wire colors are screwy because we are dealing with fan and fan lights on separate switches, but on the same circuit. They used two reds in the one box, one being a traveler and one being what I believe is the fan load (I verified red wires for lights when hanging the fans). A white cord is also used as a traveler, separate from the neutrals in the one box.
Question is - is this setup safe? All of my knowledge and reading says ‘yes’ but was hoping someone with more experience can verify. I couldn’t find another post with someone with one smart switch and one regular operating together like this.
I thank you for all of the help over the years, especially the 3-way FAQ which I’ve poured over many times.
