Meross MS220 5-in-1 Smart Multifunctional Door Sensor with Bluetooth BLE, Vibration Detection, Doorbell, Night Light, and 100 dB Alarm

The Meross MS220 5-in-1 Smart Multifunctional Door Sensor with Bluetooth BLE, Vibration Detection, Doorbell, Night Light, and 100 dB Alarm is a comprehensive security and automation device designed for modern homes. This versatile sensor integrates five distinct functions into a single compact unit, allowing you to monitor entryways, detect unauthorized tampering, receive doorbell alerts, illuminate dark areas, and trigger custom smart home actions with a physical press. Built to withstand challenging environments with a weather-resistant enclosure, it integrates smoothly into your daily routine while providing reliable performance.

Advantages

This multifunctional sensor combines multiple home automation and security devices into one housing, reducing the need for separate gadgets around your doorways. The inclusion of an adjustable vibration sensor ensures that physical tampering, impacts, or forced entry attempts are detected promptly, complementing the standard magnetic door opening detection. Security is further reinforced by a loud integrated siren that deters unwanted activity locally. The built-in night light offers practical illumination for nighttime navigation, while the programmable button lets you execute customized automation scenarios effortlessly.

Suitable for

• Monitoring entry doors, windows, and gates for unauthorized access
• Detecting glass breaks, impacts, or physical tampering via vibration sensing
• Functioning as a smart doorbell to trigger audible notifications
• Providing gentle, automated pathway lighting near entrances after dark
• Triggering smart home automations and customized scenes with a physical button press

When it may not be suitable

This device may not meet your needs if you do not already own or plan to purchase a compatible Meross Bluetooth hub, as network-based features, cloud event history, and remote alerts require this intermediary hardware. Additionally, standalone operation without a hub limits internet connectivity and remote notifications.
