When a door or window opens—or if the sensor is removed—it can send app notifications and trigger automations such as alarms, camera recording, lights, or climate control. Only one wireless mode can be used at a time. Matter-over-Thread use requires a Thread border router; Zigbee use requires a compatible Zigbee hub.\u003c\/p\u003e\n\u003cp style=\"font-weight: bold; margin: 1em 0 0.5em 0;\"\u003eKEY FEATURES\u003c\/p\u003e\n\u003cul style=\"margin: 0 0 1em 0; padding-left: 1.25em;\"\u003e\n\u003cli\u003eDual protocol: Zigbee 3.0 or Matter over Thread (IEEE 802.15.4).
