Can I activate the RGB Kit without using the Bluetooth App?

Can I use the Underlight Bluetooth kit without the Bluetooth App?

The short answer is YES.

The Underlight X6 and X8 RGB kits can be used without a Bluetooth connection. Each kit has a manual override switch to allow the main control unit to be fully switched off from DC power. When the switch is activated without Bluetooth connectivity, the RGB lights will power to the default colour.
