Product description

The SNZB-04P is the upgraded version of the popular SNZB-04 door/window sensor, now with improved design and performance. Utilising the Zigbee 3.0 protocol, it seamlessly integrates with compatible smart home hubs like Home Assistant (ZHA or Zigbee2QWTT), Sonoff eWeLink apps and Amazon's Echo Plus 2nd Gen.

What sets the SNZB-04P apart is its enhanced security features. It is equipped with a tamper-proof design that will trigger an alert and send a notification to your smartphone if the sensor is disturbed or removed from its installed location. This gives you peace of mind knowing your home is protected against unauthorised entry.

The sensor also boasts an impressive 5-year battery life, reducing the hassle of frequent battery changes. With a maximum installation distance of 20mm between transmitter and magnet, it can accommodate a wide range of door and window configurations.

One of the standout features is the ability to use the sensor's on/off status as a trigger for creating custom scenes and automations. For example, you can set lights to turn on automatically when a door is opened or trigger visual/audio alarms for added security.

Thanks to Zigbee's local intelligence, the SNZB-04P can activate linked scenes and automations even if your Wi-Fi network or internet goes down, ensuring consistent reliability with lower latency.

Upgrade your smart home with the SNZB-04P door/window sensor for enhanced security, automation capabilities, and seamless integration with your Zigbee ecosystem.
