Keep your home secure and your automations running smoothly. The Sonoff Door Window Sensor R2 is a slim Zigbee 3.0 contact sensor that monitors doors, windows, gates, or cabinets in real time. It features immediate eWeLink app alerts, active tamper detection, and highly flexible mounting for wide gaps. Powered by two standard AAA batteries, it serves as a reliable, discreet first line of defense.
Description
Upgrade your home security and ambient automation with the Sonoff Door Window Sensor R2 (Zigbee). This second-generation contact sensor discreetly blends onto any frame, picking up the exact moment a door or window is breached. By detecting the physical separation between its wireless transmitter and the magnet, it sends instant data to your smart network.
Beyond standard alerts, this versatile sensor integrates deeply with the eWeLink ecosystem. You can use it to trigger a chain reaction of smart actions—such as turning on entrance lights when you arrive, commanding a smart camera to start recording, or turning off the air conditioning when a window is left open.
Key Features
Real-Time Push Alerts: Instantly sends notification alerts to your mobile phone via the eWeLink app the moment separation is detected.
Active Tamper Detection: Built-in security features trigger a panic warning immediately if the sensor is forcefully pried off or damaged.
Flexible Mounting Options: Supports horizontal alignment (30mm gap detection range) and vertical alignment (15mm gap detection range) to accommodate uneven frames or wide gaps.
Smart Automation Linkage: Seamlessly triggers localized smart scenes, smart sirens, or security camera workflows when paired with a compatible Zigbee hub.
Accessible Power Source: Powered by two standard AAA batteries, making it effortless to maintain and replace anywhere in South Africa.

Does this sensor work directly with my home Wi-Fi network? +
No. It uses the low-energy Zigbee 3.0 protocol, which requires a compatible hub like the Sonoff Zigbee Bridge Pro to connect to your Wi-Fi network and the app.
-
What happens if someone tries to rip the sensor off the wall? +
The sensor features advanced anti-tamper hardware. If it is forced off its mounting surface, it will instantly broadcast a tamper alert to your phone.
-
Can I use this on outdoor property gates or garage doors? +
It can be used on indoor gates or garage entryways. However, if used outdoors, it must be completely shielded from water and harsh weather elements since it is designed for standard indoor conditions.
-
How far apart can the sensor and the magnet be placed? +
If mounted horizontally, the detection range allows a gap of up to 30mm. If mounted vertically, the maximum permissible gap is 15mm.
