Hi There.
Thank you for bringing this to our attention. I appreciate your taking the time to raise this inquiry regarding the 30" Range Hood with WiFi and Bluetooth.
This appliance has a feature that allows you to pair compatible Samsung cooktops and your hood via Bluetooth. After you enable this function and pair your hood and a compatible cooktop, the hood fan will automatically come on at low speed when you turn on a cooktop element. The hood fan will also shut off automatically when you turn off the cooktop elements. In addition, after the hood and compatible cooktop are paired, you can download the Smart Things app to a mobile device and then use the Smart Things app to:
• Monitor and control the On/Off status of the hood.
• Monitor and control the fan speed.
• Monitor and control the lights.
• Set the hood shut-off timer with the time-up alarm.
Here is a link on how to properly connect the hood and light statuses.
