Problem & Solution
Securing every window and door in your home often feels like an expensive undertaking, especially with big-brand security systems pushing high hardware costs and mandatory monthly subscriptions. Leaving entry points unmonitored leaves you feeling anxious about unexpected intrusions or simply forgetting whether you closed the back door before heading to work.
While Wi-Fi contact sensors offer a low barrier to entry, they frequently suffer from high latency, frequent disconnections, and rapid battery drain. Waiting several seconds for a light to turn on when opening a closet or pantry door completely ruins the smart home automation experience.
This Zigbee Door and Window Sensor completely eliminates those headaches. Operating on low-power, local-first Zigbee communication, it reports open and closed states instantaneously to your smart home controller. At under $6 per unit, you can affordably equip every door, window, drawer, and gate in your house without breaking the bank or sacrificing network stability.

FAQ
No, it uses the Zigbee protocol. You will need a Zigbee hub (such as a Sonoff Zigbee Dongle for Home Assistant, Hubitat, or an Alexa Echo with a built-in hub).
Because Zigbee operates locally, event reporting is near-instantaneous (typically under 200 milliseconds), making it ideal for automation triggers like turning on room lights upon opening a door.
Not at all. It comes with pre-cut double-sided adhesive tape, allowing you to mount both the sensor body and magnet without drilling holes or leaving permanent damage.
