The Shelly Door/Window 2 is a battery-powered Wi‑Fi sensor for open/close, tilt, vibration, temperature, and ambient light. With support for app, MQTT, CoAP, and REST integration—no hub required. Ideal for automation, security alerts, and environmental tracking.
The Shelly Door/Window 2 is a Wi‑Fi smart sensor designed for accurate door/window status detection plus ambient sensing—all without needing a hub. It delivers flexible installation, temperature and light tracking, and full ecosystem control via MQTT, CoAP, REST, and native apps.
Key Features:
Direct Wi‑Fi Control: Connects to 2.4 GHz Wi‑Fi—no hub required
Valve Detection Functions: Reports open/close events, tilt angle (for hinged windows), plus vibration detection
Environmental Sensors: Integrated temperature (±1 °C accuracy) and ambient light (lux) measurement
Battery Powered: Uses 2×CR123A cells for approximately 18 months of operation
Low Power Architecture: Sleeps until door/window triggers or schedule threshold, then wakes and reports changes
Automations & Scheduling: Supports timed events, sunrise/sunset routines, and local or cloud-based control
Remote & Local Support: Works via Shelly app, MQTT, CoAP, or HTTP APIs
Wireless Range: Up to ~50 m outdoor and ~30 m indoor, depending on building materials
Compact Form Factor: Sensor module measures ~82×23×20 mm; magnet ~52×16×13 mm
