Amazon Basics HPD-A321N-WB Smart Motion Sensor Dimmer Switch: Works with Alexa for voice control
This smart motion sensor dimmer switch is for homeowners who want to upgrade a hallway or stairwell light to work automatically, saving you from fumbling in the dark. While many focus on home security, this switch offers convenience and energy savings by ensuring lights are only on when needed.
