Add Device: In the Refoss app, tap the "+" icon to add a new device. Select "Smart Bulb" from the list.
Pairing Mode: If the bulb is not flashing, you may need to reset it to enter pairing mode. To reset, turn the light bulb ON/OFF 5 times within 5 seconds, then leave it OFF for 5 seconds. The bulb will flash to indicate it's in pairing mode.
