MEROSS MS220-EU Smart multifunctional door sensor

The MEROSS MS220-EU is a multifunctional door sensor that detects door openings and vibrations, while also serving as a doorbell, night light and smart home control button. Its 100 dB alarm can alert you to unwanted opening, and vibration sensitivity can be adjusted to suit the installation location. It connects via Bluetooth Low Energy (BLE). A compatible Meross Bluetooth hub is required for network features such as cloud event history, as well as to play the doorbell chime.

The IP65-rated housing is protected against dust and water jets, and the sensor operates in temperatures from -20 °C to 60 °C. It runs on a replaceable CR123A battery. The integrated night light adds illumination near the door, while the button can be configured to control selected smart home functions or automations. The sensor is compatible with smartphones running iOS 13 or later, or Android 8.0 or later.
