Nous E3 Smart Zigbee Door/Window Sensor (Tuya)

Product detailed description

🚪 Nous E3: Secure Your Windows and Doors (Red Dot Winner)

The Nous E3 smart door and window sensor—a proud winner of the prestigious Red Dot Design Award 2020—is the elegant, invisible guardian of your home. Comprising two small pieces (the sensor and the magnet), it instantly detects any opening or closing of doors, windows, garage gates, or even secure cabinet drawers. You will always know if you remembered to safely close up before leaving the house.

Push Notifications and Smart Scenes

Integrated seamlessly with the Tuya, Smart Life, or Nous Smart Home apps, you have complete oversight directly on your phone. The device precisely logs every open and close event with timestamps.
This sensor shines as a powerful trigger for smart home automation scenes:

• Security: If the sensor detects a door opening while your house is "Armed/Away", it instantly fires a push notification to your phone and triggers a smart siren.
• Convenience: If the hallway door opens after sunset, automatically turn on the smart LED strip so you don't walk into a dark room.
• Energy Saving: When you open a window to ventilate a room, the system automatically shuts off the smart radiator thermostat below it to stop wasting heating energy.

Exceptional Design and Reliability

The Nous E3 is engineered for maximum reliability. Its high-quality magnetic contact operates flawlessly even with a generous gap of up to 15 mm between the sensor and the magnet. This allows it to be installed easily on virtually all types of window and door profiles, including older frames with uneven surfaces. Rigorously lab-tested, it guarantees 100% dependable performance without false triggers.

Technical Specifications:

• Battery Life: Powered by a standard 3V (CR2) lithium battery, which provides several years of continuous operation thanks to ultra-low energy consumption.
• Protocol: ZigBee (IEEE 802.15.4) ensures zero-latency, highly stable communication via your smart home mesh network.
• Dimensions: Ultra-compact chassis measuring just 28.5 x 18.0 x 56.7 mm.

Important Note: This sensor communicates via Zigbee. It strictly requires a central smart home hub (Zigbee Gateway, e.g., the Nous E1) to connect to your app. It does not pair directly with your Wi-Fi router.
