SONOFF SNZB-04P Zigbee Door Window Sensor | Zigbee Bridge-Hub Required

The Sonoff SNZB‑04P Zigbee Door Window Sensor helps you secure your home with smart, real-time alerts. It detects when a door or window opens or closes and sends instant notifications to your phone. It connects to your Zigbee hub and works with Smart Life, Alexa, Google Home, and Home Assistant.

This smart sensor is compact and easy to install. Just peel and stick it on your door or window frame. No wiring is needed. Once connected, it can trigger automations like turning on lights when a door opens, or sending alerts if someone enters at night.

The SNZB‑04P offers strong Zigbee connectivity and low power usage. It runs on a long-lasting CR2032 battery and has a signal range that covers large homes. If you use other Zigbee devices, you can create smart scenes—like turning off the AC when a window opens.

It’s great for use on front doors, balconies, windows, cabinets, or even fridges. You’ll know right away if anything’s left open or accessed unexpectedly. The sensor is also tamper-protected, so you’ll get notified if anyone tries to remove it.

Pairing it with a Zigbee bridge allows integration with your entire smart home setup. It can work alongside motion sensors, switches, or alarms for smarter automation. Even if your Wi‑Fi goes down, the Zigbee mesh keeps your automations running locally.

With its simple look and compact design, it blends into any interior. It’s ideal for people who want extra security, smart control, and peace of mind—without a complicated setup.

Upgrade your home security with this easy-to-use, affordable sensor. Stay informed, automate your home, and protect your space with smart entry detection.
