Sonoff DW2 WIFI Wi-Fi Wireless Door Window Sensor: Works without gateway connection via Wi-Fi
For the busy homeowner who wants to secure entry points without complex setups, the SONOFF DW2 Wi-Fi Wireless Door Window Sensor is your go-to tool. Think of it as your silent sentinel for checking on a back door left ajar or a window after the kids come home from school. While many focus on home security, this sensor offers peace of mind through seamless integration into your daily routine, letting you verify statuses instantly without second-guessing.
You get real-time push notifications to your phone the moment a door or window opens, so you know before a text from a neighbor. Pair it with a SONOFF indoor camera or an old smartphone via the app, and you can view what's happening, not just get an alert. This two-way audio capability enhances monitoring, making it Alexa compatible for voice commands. Installation is tool-free with 3M adhesive, fitting on sliding doors or hinged windows in minutes. History records save notifications for three months, so you can review events and stay informed effortlessly.
