When you have downloaded the Nordlux Smart Light App you can pair it with Alexa to control the Nordlux Smart Light App through voice control. Through Alexa you can give commands to the App so you can control the light, light moods, rooms and routines. It should be noted that when you use the Nordlux App and Alexa App to control the light bulb, to avoid the impact of the phone's local Bluetooth control, turn off the phone's Bluetooth first for a better experience.
