작동 지침
The Meross MST200 offers various ways to manage your watering needs:
Independent 2-Zone Control
The MST200 features two independently programmable outlets. You can set different watering schedules and durations for each zone, allowing for customized irrigation of your lawn, garden beds, or other areas without interference.

Automatic Watering Programs
Create up to 20 personalized watering programs per outlet using the Meross app. Define specific days, times, and durations for each zone. This is ideal for various applications such as drip irrigation, filling pools, or maintaining fountains.
Smart Rain Delay
The MST200 synchronizes with the nearest weather station via the Meross app. Before each scheduled irrigation cycle, it automatically checks the latest weather forecast. If the total predicted rainfall for the current and next day meets or exceeds your predefined threshold in the app (e.g., 8.9 mm), the irrigation program will be intelligently skipped to prevent overwatering and conserve water.

The integrated water flow meter allows you to precisely track water consumption for each zone and the total output for daily, weekly, and monthly periods. This data helps you optimize your irrigation schedule, ensure plant health, and reduce water bills.
