Product Information
Sonoff Zigbee Door/Window Sensor (SNZB-04P)
A wireless sensor that detects when a door or window is opened or closed and instantly alerts you on your phone. It connects through a Zigbee (a wireless smart home protocol that connects devices through a hub) hub, so it works reliably even if your internet goes down. With a 5+ year battery, it’s a set-and-forget security device.
Key Features:
- Instant Alerts: Get a phone notification the moment a door or window is opened.
- 5+ Year Battery: Long-lasting battery — no frequent replacements.
- Tamper-Proof Alert: If someone tries to remove the sensor, you’ll be notified.
- Works Offline: Uses Zigbee, so local automations continue even without internet.
- Smart Automations: Trigger lights, alarms, or cameras when a door/window opens.
- Easy Installation: Peel-and-stick with adhesive — one piece on the door, one on the frame.
💡 Pro Tip: Place one on every exterior door and window. Set an automation: if any door or window opens while you’re away, you get an instant notification and the camera starts recording.
