Meross 3-in-1 Smart Door and Window Sensor with Doorbell Mode, MS220 - The Doorbell Threshold
Meross · $
The Meross MS220 is a 3-in-1 door and window sensor with a second life as a doorbell. Its button can trigger lights, scenes, and automations, while Doorbell Mode sends an alert through the Meross hub, app, and connected devices. IP66 protection and an operating range from -20°C to 60°C give it a wider brief than a hallway contact sensor. The 1700mAh CR123A battery is rated for up to three years. A built-in buzzer can reach 100dB, with selectable sounds or mute control. Smart features require the Meross MSH450P hub.
