2 Way Wall Switch Wiring. A two-way electrical switch can have multiple uses in a home environment. These two way switches have a single pole double throw (SPDT) configuration.
In this wiring connection we use two way switches in which we have three terminals, in these terminals one is common and two for connection. we can use it for many connection using different connection methods. For example we use it changing flow of current positive to negative etc. For example, you can use this device to install a dimmer slider that operates not just the light, but Use the screwdriver to remove the faceplate from the wall.
With that type there is no way to hook it up Wall switch for fan puts fan on at what-ever speed you last left it, and remote with control speed if you want to change it.

If you have three way switches, it will be challenging replacing them with Sonoffs. Wire size needs to be suffi cient to carry the motor load. Do not connect the blue wire to any other wiring or to ground.
