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).Â
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 Androidâ„¢ device
- The latest Wemo App available on the Google Playâ„¢
NOTES:
- The Wemo 3-Way Light Switch is not designed to work with metal faceplates as these can interfere with the Wi-Fi signal.
