Compatibility Notice: This sensor requires the Meross MSH450P (Matter Smart Hub Pro) for smart features. It is NOT compatible with the MSH450. Please check your Hub model before purchasing.

  • Smart Automation withthe Upgraded Meross Hub: The MS220 requires the MSH450 Pro Hub (sold separately) to unlock its smart features. The upgraded Hub supports both new Bluetooth sensors and existing 433MHz devices, offering voice alerts, local alarms, and Matter integration for a more connected and expandable smart home.

  • Home Assistant Integration: Connect directly to Home Assistant without a Meross Hub. Requires Home Assistant with HACS installed and a Bluetooth adapter or ESPHome Bluetooth Proxy configured.

  • More Than a Door Sensor: Switch between Door Sensor and Doorbell modes to fit your needs. In Doorbell Mode, a single press triggers alerts through the Hub, app, and other connected devices, so you never miss an important visitor.
  • One Button, More Possibilities: Use the customizable button to trigger lights, scenes, and automations. Place it by the door to easily switch between Home and Away Modes with one pressturning lights on or off, activating security, adjusting curtains, and triggering other smart devices as you come and go.
  • All-Weather Protection, Long-Lasting Power: With IP66-rated protection, a wide operating temperature range of -20C to 60C, and a high-capacity 1700mAh CR123A battery, the sensor delivers up to 3 years of battery life for reliable monitoring indoors and outdoors.
  • Instant Alerts for Suspicious Activity: Detects abnormal door or window opening and closing, with adjustable vibration sensitivity to identify forced entry and unusual movement. Connect to the Hub, App, and other smart devices for timely alerts. The built-in buzzer delivers up to 100dB of sound and works with the LED indicator. Choose from multiple alert sounds or mute the buzzer for flexible local alerts.
  • Portable Protection, Wherever You Go: Compact and easy to carry, it can be used in motels, hotels, and other temporary accommodations. When unusual activity is detected, the built-in buzzer delivers a loud 100dB alar
