Why Sensors Matter
Smart sensors are the silent backbone of automation. They let your home react instantly — turning on lights, sending alerts, or shutting off water automatically.
Where to Use Them
Place motion sensors in halls, contact sensors on doors/windows, water detectors near sinks or basements, and temp sensors in nurseries or server rooms.
