Visit Sonoff SNZB-04P<\/strong> is an opening\/closing sensor for doors or windows using the Zigbee 3.0<\/strong>designed for simple, reliable integration into existing systems home automation with Raspberry Pi<\/strong>.<\/p>\n

Enhanced detection and safety<\/h3>\n

This sensor consists of a magnet and a sensor body, which communicate via a magnetic field. When the magnet separates from the main module (e.g. when a door is opened), the event is transmitted immediately. The SNZB-04P also features an integrated anti-theft (tamper)<\/strong>The system is equipped with a \"tamper-proof\" alarm system, which provides an instant alert in the event of tampering with the device or unauthorized access.<\/p>\n

Remarkable autonomy<\/h3>\n

The sensor is powered by a battery CR2477<\/strong> included, guaranteeing over 5 years<\/strong> depending on use. Thanks to its low standby power consumption and optimized Zigbee protocol, it requires very little maintenance.<\/p>\n

Easy installation and discreet design<\/h3>\n
    \n
  • Compact dimensions: approx. 50.5 \u00d7 32 \u00d7 21.9 mm<\/strong> for the main module, and 27 \u00d7 12 \u00d7 12.4 mm<\/strong> for the magnet.<\/li>\n
  • Screwless installation thanks to 3M adhesive tape<\/strong> simple, fast and non-invasive.<\/li>\n
  • Maximum detection distance between the two elements : \u2264 20 mm<\/strong>suitable for most conventional windows and doors.<\/li>\n<\/ul>\n

    Zigbee compatibility and operating locality<\/h3>\n

    Operating under Zigbee 3.0<\/strong>This sensor integrates perfectly with standard Zigbee gateways (USB dongle on Raspberry Pi), and is fully usable with tools such as Home Assistant or Zigbee2MQTT. It also supports local scenes<\/strong>This allows scenarios to activate devices even in the event of a network failure, with a high level of responsiveness.<\/p>\n

    Key technical specifications<\/h3>\n
      \n
    • Operating temperature<\/strong> : -10 \u00b0C to +60 \u00b0C<\/li>\n
    • Operating humidity<\/strong> 5 % to 95 % (non-condensing)<\/li>\n
    • Weight<\/strong> approx. 33 g<\/li>\n
    • Material<\/strong> Sturdy, lightweight polycarbonate housing<\/li>\n<\/ul>\n

      Concrete applications with Raspberry Pi (Home Assistant \/ Node-RED)<\/h3>\n
        \n
      • Intelligent safety<\/strong> : receive immediate notification when a door opens unexpectedly.<\/li>\n
      • Contextual automations<\/strong> These include turning on lights at entrances, activating cameras, simulating a presence, and switching off lights at closing time.<\/li>\n
      • Home management<\/strong> The system can be used to: switch off sockets in the event of absence detected by opening\/closing, trigger an audible or visual alarm.<\/li>\n
      • Usage history<\/strong> Log openings on a dashboard to analyze habits or optimize energy consumption.<\/li>\n<\/ul>\n

        Conclusion<\/h3>\n

        Visit Sonoff SNZB-04P<\/strong> is a simple-to-install, yet feature-rich opening\/closing sensor. Thanks to its Zigbee compatibility, seamless integration with a Raspberry Pi, long battery life and anti-theft functions, it's a robust and practical way to enhance the security and automation of your connected home.<\/p>","protected":false},"excerpt":{"rendered":"
