I have an existing three way setup using the TP Link wifi-three way switch. I’d like to convert it to the Honeywell Z-wave in-wall switch with an add-on but the wiring configuration does not seem to fit. The current setup involves two traveler wires (Red and Yellow) plus the line wired on the switch itself and the load and neutral pig-tailed to the switch’s neutral line. The second switch is wired the exact same way.
Trying to do the same setup with the Honeywell switch plus the add-on doesn’t look like it would be a viable solution as the add-on does not have space for the line wire.
I’m attaching a pic of how my current smart switch is wired. You can’t see it well in the pic, but there’s a black wire pig-tailed in with the neutral wire to the switch’s neutral wire. I’d appreciate any advice.
