Need help writing a Zwave+ device handler

Probably the simplest is to just use an auxiliary switch that is already designed to not control the load. It does exactly what you’re asking for, no special device type handler needed. And usually costs less then a master switch would.

JD, why does an accessory switch have three wires if it does not actually connect to a load? My expectation is that this has to wire to the master switch. Is that correct?

Different models use different wiring patterns.

The GE auxiliary switches do not have a radio inside and communicate with their master by physical traveler wire.

[FAQ] GE 3-Way Wiring

I’ve decided to put this FAQ together to help those with questions about installing GE 3-way switches. Definitions of terms: Line: The hot wire from the breaker (usually black) Neutral: The return wire for circuits (usually white) Load: The wire that will be hot when the circuit is completed to your light (usually black) Traveler: In existing 3-way wiring, this wire toggles hot between two switches. In a smart switch 3-way configuration, a smaller charge is looped through the add-on switch. Some things to know: 3-way wiring for smart switches is different than standard 3 way wiring. You cannot use dumb 3-way switches with most smart switches (You must purchase the matching GE add-on switch to wire with your GE smart master switch). If the line is wired into the light fixture, you …

The gocontrol auxiliary switches do have a radio inside and communicate with their master wirelessly. They do not use a physical traveler wire. They do use the neutral wire to power the radio in the auxiliary.

So I’m not sure what you meant by “three wires” but different models are different.
