eWeLink WiFi Door and Window Contact Sensor

Check whether a door or window is open through eWeLink using a battery-powered Wi-Fi magnetic contact sensor.

✅ See the reported contact state - The app provides the supported open/closed status for the connected sensor.

✅ Receive supported opening notifications - A working Wi-Fi and app connection can bring the event to your phone.

✅ Plan battery replacement - The low-battery reminder draws attention to the sensor's power condition.

Keep a door-state check in your pocket

Mount the sensor and magnet in the positions required by the instructions, then pair the device with a 2.4 GHz Wi-Fi network. Test both opening and closing from the app before normal use.

This sensor provides a contact-state report rather than a physical lock or monitored response. Check signal strength at the door and notification permissions on the phone so the installed setup works as expected.
