Setting up the Wemo 3-Way Light Switch using your Android device

Before you begin setting up the Wemo® WiFi Smart 3-Way Light Switch, WLS0403 with the Wemo App, make sure you have the following:
  • The default Wemo Wi-Fi name.  The Wemo 3-Way Light Switch's Wi-Fi name is Wemo.LS3W.xxx (where xxx are the last three characters of the serial number). 
NOTE:  You can locate the last three characters of the serial number at the bottom of the Light Switch.  This will also help you identify one Wemo 3-Way Light Switch from the other (if you are setting up multiple Light Switches).
  • A Wemo 3-Way Light Switch that is already installed to your electrical line and is functioning.  For hardware installation tips, click here.
  • An Android™ device
  • The latest Wemo App available on the Google Play™
  • The Wemo 3-Way Light Switch is not designed to work with metal faceplates as these can interfere with the Wi-Fi signal.
  • The Wemo 3-Way Light Switch cannot replace a 4-way light switch.
