Each Switch has to be individually paired. Anywhere you have a three way or four-way set up you need to install all of the switches for that light fixture at the same time. With GE switches, only the master actually gets paired to the smartthings hub, the auxiliaries are physically wired to the master via the traveler wires.

> 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 …

But every master switch has to be individually paired, if that’s what you’re asking.

If you are asking if you can do one master switch on Monday, then another master switch on Thursday, then three or four master switches over the weekend, sure, that’s no problem, again assuming that you do all of the devices for a three-way at the same time.

If you’re asking if you can wire all the switches at once and then go back and pair them individually then, yes, and some people do that when they have the switches installed by an electrician. The switches will work as physical switches even if they haven’t been paired yet.
