ZigBee 3.0 Door Window Sensor Sonoff SNZB-04P (up to 5 years battery life)

SONOFF SNZB-04P ZigBee door/window opening sensor

The SNZB-04P sensor is the latest version of SONOFF's popular solution dedicated to monitoring door and window opening in smart home systems. Thanks to the ZigBee 3.0 protocol, it works with a wide range of gateways and hubs, ensuring reliable and fast communication.

Key features:

• Door and window monitoring
  You can use the signal from the sensor to trigger lighting when the door is opened, notifications in case of unauthorised access, as well as sound and light alarms.

• Tamper sensor
  The built-in tamper alert mechanism sends a notification when someone tries to tamper with the sensor.

• Long battery life (up to 5 years)
  The new CR2477 battery avoids frequent battery changes - up to 50 violations per day at room temperature.

• ZigBee 3.0 communication
  
  

• Support for local scenes
  Even in the absence of an internet connection, the sensor can still trigger local automations between ZigBee devices (as long as they remain powered).

• Small footprint and aesthetically pleasing design
  New streamlined shape and increased magnet range (up to 20 mm).

• Integration with Home Assistant (ZigBee2MQTT)
  Easy implementation in OpenSource systems (e.g. Home Assistant) if you have a suitable ZigBee gateway (such as the SONOFF ZBDongle).

Why ZigBee?

• Mesh network - 230V powered devices (e.g. smart sockets or light bulbs) can act as signal boosters.
• Low power consumption - ideal for battery-powered sensors, ensures long operating times and stable operation.
• Improved range - thanks to the function of passing the signal through other ZigBee accessories.

Sensor Works with hub gateways such as:

• SONOFF NSPanel Pro
• SONOFF iHost
• SONOFF ZB Bridge Pro
• SONOFF ZBDongle-E / ZBDongle-P
• Echo Plus 2nd Generation

Tamper sensor

A built-in mechanism to respond to any unauthorised tampering of the sensor. This means that when the sensor is peeled off or disassembled, it can send an alert to the application, informing you of a potential tampering event. You can respond to a tampering event by, for example, setting off an alarm or automatically switching on selected devices in the home.
