Leak Protection
Pair with a water leak sensor. When a leak is detected, the valve automatically shuts off — even if you're away. Prevents flood damage to floors, ceilings, and electronics.
Holiday Shutoff
Going on holiday? Close the water main from your phone. No more worrying about burst pipes or geyser leaks while you're away.
Garden Irrigation
Schedule watering times with cycle timers. Open the valve in the morning, close at night. Automate your irrigation without manual intervention.
Rental Properties
Manage water supply remotely for Airbnb, flats, or rental units. Turn water on for check-in, off at checkout. Monitor usage from anywhere.

Remote open/close from anywhere. Check valve status in real time. Works on WiFi, 3G, or 4G. iOS and Android. Share control with family members.
Alarm Automation
Link with eWeLink water immersion sensor. Auto-close on leak detection. "Home mode" opens valve, "Away mode" closes — reduce leak risk automatically.
Timer & Scheduling
Three modes: timed, delayed, and cycle. E.g. close at 7:30 AM (work), open at 17:30 (return home). Up to 8 active timers. Work even when WiFi is down.
