Another 3-way Help Request

Hi all,

I’ve got another 3-way switch that I’m trying to replace and I thought I would seek advice from the experts before I delve into it. I’ve got the Honeywell Z-wave in-wall switch and an add-on ready to go once I’ve got the wiring figured out.

Here’s Box1 which I have determined to be the “hot” box:

And this is Box 2:

So, of course, any advice you can give me would be greatly appreciated, and, if I need to get better pics on the boxes, please let me know.

Have a look here

Looks like you’ve got “light between the switches #2” configuration.

Just an aside: the Zooz ZEN26 switch and ZEN27 dimmer let you smarten a 3-way by only replacing one side. The other side retains the dumb switch and does not need to be required. If you’re doing a dimmer, you don’t gain the ability to dim from both switches, the dumb side remains on/off only. And there are some load limits that need to be watched. But it’s a significant cost savings.

Not so sure about that. Looks like the 3 way was added after the fact given 14-3 goes down via track and 2 14-2s go in back of wall for old switch.

Appears that line and load are in that first box. @tommymac remove the wire nuts and use a multimeter to measure the black and white wires. Should read 120V if my suspicion is correct.

Yes, I noticed that the white wire in the 14-3 is actually white while the ones in the 14-2 cables have yellowed with age.

But the diagram I referenced still looks correct. It looks to me like it’s actually “line and load in the same box with added 3-way”

Your suspicion is correct. 120v when I use the multimeter on the wire-nutted black and white wires.

Interesting I hadn’t paid that close attention to the wiring diagram names and when I read “between the switches” I really thought you meant that with 14-3 going to light. I would not agree with that name at all but know I am splitting hairs.

Master will go in that first box then and Aux in second. You good with wiring?

Yep. This did the trick.

Thanks to you both for your help and advice on this. I was a bit leery on this one and wasn’t sure if I could even pull it off.
