The Sonoff SNZB-04PR2 (SenseGuard DW Gen2) is the advanced successor to Sonoff's well-known \u003ca href=\"\/en\/collections\/raamsensor-deursensor\" title=\"View all window and door sensors on slimhuisje.nl\"\u003edoor and window sensors\u003c\/a\u003e. With its extremely slim profile of only 13.5 mm deep, contactless Hall sensor technology, and built-in physical anti-tamper button, this is the ideal wireless contact sensor for any frame.

This means no mechanical friction or wear, ensuring a significantly longer lifespan and extremely reliable status detection. Thanks to its streamlined design of 90 x 26 x 13.5 mm, this Gen2 sensor is barely noticeable and fits perfectly on narrow plastic, wooden, or aluminum window and door frames.\u003c\/p\u003e\n\u003ch3\u003eEconomical AAA Power \u0026amp; Active Tamper Protection (Anti-Tamper)\u003c\/h3\u003e\n\u003cp\u003eOne of the biggest practical upgrades of the SenseGuard DW Gen2 is its use of two standard AAA batteries. These are inexpensive to purchase and easy to replace, while the sensor, thanks to the energy-efficient Zigbee 3.0 protocol, lasts up to 3 years. Furthermore, there is a physical anti-tamper button on the back. Should an unauthorized person try to pull the sensor from the frame or door, a tamper alarm will immediately be sent to your smart home controller.\u003c\/p\u003e\n\u003ch3\u003eEcosystems \u0026amp; Compatibility\u003c\/h3\u003e\n\u003cul\u003e\n\n\u003cli\u003e\n\n\u003cstrong\u003e\u003ca href=\"\/en\/collections\/home-assistant\" title=\"View Home Assistant hardware on slimhuisje.nl\"\u003eHome Assistant\u003c\/a\u003e:\u003c\/strong\u003e Works excellently via ZHA and Zigbee2MQTT (Z2M) in combination with a suitable \u003ca href=\"\/en\/collections\/smart-home-usb-controller?sort_by=best-selling\u0026amp;filter.p.m.custom.protocol=Zigbee\" title=\"View Zigbee coordinators on slimhuisje.nl\"\u003eZigbee coordinator\u003c\/a\u003e.

You can order economical AAA alkaline or lithium batteries directly with your purchase.\u003c\/p\u003e\n\u003ch3\u003eHow does the physical anti-tamper protection work?\u003c\/h3\u003e\n\u003cp\u003eOn the back there is a spring-loaded push button that remains pressed when the sensor is securely mounted on the door or frame. Should someone pull the sensor off or dismantle it, the button will release, and the sensor will immediately send a tamper alarm to your smart home platform.\u003c\/p\u003e\n\u003ch3\u003eDo I need a special hub or Zigbee coordinator?\u003c\/h3\u003e\n\u003cp\u003eYes, the SNZB-04PR2 communicates via the Zigbee 3.0 protocol.
