Window and Door Sensor Nous E3 — Zigbee wireless contact sensor for open/close detection

Nous E3 is a Zigbee wireless contact sensor for detecting the open or closed state of windows and doors. The compact, battery-powered device reports status changes over the Zigbee network to compatible smart home hubs, allowing remote monitoring, event-triggered automations and integration with home security systems. Its low-profile design and magnetic reed sensor make it suitable for concealed mounting on frames and sashes where reliable state detection is required.

Advantages

The sensor offers wireless Zigbee connectivity for low-latency status updates and compatibility with a range of Zigbee hubs. Its compact form factor and magnetic activation mechanism enable unobtrusive installation without routing wires. Battery operation provides placement flexibility, and the device supports rapid detection of open/close transitions for accurate automation and alerting. The sensor’s straightforward design simplifies pairing and integration into existing smart home setups.

Suitable for

• Home security monitoring of doors and windows
• Triggering automation scenes (lights, alarms, HVAC)
• Remote status reporting for occupied/unoccupied workflows
• Concealed or surface mounting on frames and sashes

Key specifications

• Wireless protocol: Zigbee for local smart home integration
• Power source: battery operation for flexible placement
• Detection method: magnetic contact (reed switch) for open/close sensing
• Form factor: compact, low-profile housing suitable for frame or sash mounting
• Report type: binary status reports (open/closed) and state change notifications

How to use

Install the sensor by mounting the main body and the accompanying magnet on the window or door and its frame so that the magnet aligns with the sensor when the opening is closed. Insert the battery following the manufacturer’s polarity instructions, then put the device into pairing mode and add it to a Zigbee-compatible hub according to the hub’s inclusion procedure. After successful pairing, configure automation rules or notifications in the hub’s app to receive open/close alerts or trigger scenes.

Usage recommendations

Position the sensor and magnet within the recommended gap (typically a few millimetres) to ensure reliable magnetic activation. Avoid placing the magnet near large ferrous objects or strong electromagnetic sources. Check battery level periodically through the hub and replace the battery when the hub reports low battery to maintain uninterrupted reporting and automation.
