The Meross MS220 Smart Multifunctional Door Sensor combines a door-opening sensor, vibration detector, doorbell, night light, and programmable button in one compact device. With a 100 dB alarm, Bluetooth Low Energy wireless connectivity, and IP65 protection, it helps improve the security and convenience of your smart home.
The Meross MS220 monitors door opening and closing while also detecting vibrations or impacts, such as those caused by an attempted unauthorized intrusion. The vibration sensor sensitivity can be adjusted according to the installation location. When unwanted activity is detected, the built-in alarm provides an alert with a volume of up to 100 dB.
The multifunctional button can be used as a doorbell or to trigger custom scenes and automations in your smart home. The built-in night light provides gentle illumination around the door after dark.
For network functions, including cloud event history and doorbell playback, a compatible Meross Bluetooth hub and an available Wi-Fi network are required. The sensor is powered by a replaceable CR123A battery, which is included in the package.
