After you configure your LoveLight you can reset the WiFi settings by holding your hand over the glass touch surface for 2 minutes. After two minutes your light will blink orange. At that point you can remove your hand and reconfigure your LoveLight.
This process works best if:
1) You set your LoveLight on it's back prior to turning it on
2) You use 3-4 fingers and place them in the lower left hand corner of the LoveLight, making sure to make good contact with the surface of the glass.
Alternatively, if your light is currently online, you can click "Deregister Light" under the Light's settings in your LoveLight app.
