Eliminate fumbling in dark corridors by installing this sound activated switch that powers your fixtures the instant you enter. Built for homeowners and renters who refuse to rewire existing circuits, this automatic light control module captures natural footsteps and conversational audio to deliver reliable hands free lighting without manual contact.
A dedicated smart home lighting relay that replaces standard wall controls using high sensitivity acoustic detection. Unlike optical motion units that fail in drafty stairwells or behind open doors, this voice sensor technology tracks human rhythm patterns and adjusts power delivery automatically. It integrates directly into common circuits to support LED downlights, ceiling lamps, panel lights, and standard bulbs.
Drive measurable energy reduction while guaranteeing consistent safety. As an energy efficient switch, this unit eliminates phantom draw and forgotten illumination, cutting monthly electricity waste. The streamlined installation process protects structural finishes, making it a practical upgrade for aging apartments and modern renovations alike.

A thing came for 14 days, without being in robots, and I think I will not start the problems, the Chinese will not be shy)
, There is a reaction to the sound only in the dark, there is a light after the publication of the sound. If you close the window with your finger and then make a sound, it works and burns for 40 seconds. This can be applied as a short alarm only. But the light window in the center, if sealed with a piece of dark duct tape, will work on the sound during the day.
Works. but only in the dark. Reacts to sound.
As you describe it. Quality nice

Works very well
Not used yet
I just checked it, did not include it in the work. Works fine, but the triggering distance is small-I don't understand words, you have to clap deafeningly!
Works clearly, a great option for stair openings.
