Know when doors and windows open, even when you're away

Get instant alerts on your phone whenever someone opens a door or window in your home, giving you peace of mind whether you're upstairs, at work, or on holiday.

This compact sensor takes the guesswork out of home security by sending real-time notifications straight to your smartphone through the Lenovo Link app. No more wondering if you left a window open or worrying about unexpected visitors. The wireless design means no complicated wiring, and it connects directly to your WiFi without needing an expensive hub or control panel.

The discreet white sensor blends seamlessly with most door frames and window sills, while voice control through Google Home or Alexa lets you check status hands-free while cooking or getting ready for bed. Battery-powered operation means you can install it anywhere without hunting for power points.
