Sonoff has moved away from hard-to-find coin cell batteries and unreliable mechanical \"reed\" switches of older models, opting instead for standard AAA batteries, a solid-state Hall effect sensor, and built-in physical tamper detection.\u003c\/p\u003e\n\u003cp\u003eWith an ultra-slim 13.5 mm profile, this sensor blends seamlessly with modern window and door frames, while providing instant, local feedback to your smart home server.\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003eKey features\u003c\/b\u003e\u003c\/p\u003e\n\u003cul\u003e\n\n\u003cli\u003e\n\n\u003cp\u003e\u003cb\u003eUpgrade to AAA batteries:\u003c\/b\u003e Say goodbye to expensive, less common CR series coin cells.

This results in faster and completely reliable open\/closed reporting.\u003c\/p\u003e\n\n\n\u003c\/li\u003e\n\n\u003cli\u003e\n\n\u003cp\u003e\u003cb\u003eActive tamper detection:\u003c\/b\u003e Security is built-in. On the back of the sensor is a physical tamper button that is pressed against your door frame. If an intruder tries to tear the sensor off the wall or window, the button is released and immediately triggers a tamper alert in Home Assistant or the eWeLink app.\u003c\/p\u003e\n\n\n\u003c\/li\u003e\n\n\u003cli\u003e\n\n\u003cp\u003e\u003cb\u003eUltra-slim design:\u003c\/b\u003e With a thickness of only 13.5 mm, it is significantly thinner than previous generations, allowing it to fit flat and unobtrusively on almost any door frame, cabinet, or window without catching on sliding tracks.\u003c\/p\u003e\n\n\n\u003c\/li\u003e\n\n\u003cli\u003e\n\n\u003cp\u003e\u003cb\u003eFlexible magnet installation:\u003c\/b\u003e The new sensor supports both horizontal and vertical magnet alignment, giving you greater flexibility for doors or frames with unusual trim or narrow gaps.
