1. How to install Novostella Smart tunable security light?
2. I set the security light to Sensor Mode and turned it off with Alexa. Why would it become Manual Mode after I turned it on again?
A: If the light is turned on/off by Alexa, it could automatically switch to the Manual Mode. If you need it to work in the Sensor Mode, please set it in the app or with Alexa by saying "Alexa, set the light to the Sensor Mode".
3. How can I make the security light work only at night?
A: Option 1. In Manual Mode, set a schedule to make the light automatically on/off at the time you prefer.
Option 2. In Sensor Mode, adjust the Ambient Light Sensor to “Only trigger after night”.
