- Smart Automation with the 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.
- 4-in-1 Water Detection for More Scenarios: Go beyond leak detection with Leak, Rain/Drip, Freeze, and Water Level Detection. Combine up to 3 detection conditions to trigger alerts only when your set conditions are met.
- All-Weather Protection & Freeze Alerts: Detect freezing conditions and help protect water pipes from freeze damage. Powered by a CR123A battery, the sensor delivers up to 4 years of battery life and reliable performance from -20°C to 60°C, with IP66-rated protection for dependable indoor and outdoor water safety monitoring.
- Adjustable Sensitivity & Probe Height: Customize the top electrode sensitivity and bottom probe height, and add a detection delay to fit different environments. Set the right trigger conditions to help reduce false alarms from splashes and moisture.
- Free 1.5m Extension Probe for Flexible Detection: Reach tight spaces around washing machines, dishwashers, under sinks, and more. Set the probe at your desired height to detect when water reaches a preset level, ideal for bathtubs, tanks, and other applications.
- Flexible Alerts & Smart Automation: The built-in buzzer delivers up to 100dB of adjustable sound and can be muted when needed. Get alerts through the Hub, App, or other smart devices, and trigger automations for timely responses—without disturbing others.
