What is 3way switching?
A 3-way switch is larger than a single pole switch and has three screw terminals for wiring connections, plus a ground. Two of these take traveler wires that go from one switch to the other. For the third terminal, one switch is connected to the hot supply wire while the other switch is joined to the light.

Do I need 2/3-way smart switches?
In 3way switch setup, power goes into 1st switch, through 2nd switch then to the light. So, technically, you only need one smart switch for 3-way switching to be functional; but you must put the smart switch as the 1st switch.
Can you use 3-way switch single pole?

In order for a 3-way switch to function as a single pole, the wires need to be connected to the common and one of the traveler terminals. 3-way switches can be converted to single pole in several configurations.
What is the black screw on a 3-way switch?

Why does my 3-way switch have 4 wires?
One or more four-way switches are only used between three-way switches found at each end of the circuit. A 3-way switch has 4 wires because there is a 2nd switch controlling the voltage. Two wires are incoming voltage, and the other 2 wires are out going voltage to the 2nd switch.
What is a three-way switch used for?
