Worried about a burst pipe while you're on vacation? This smart valve controller lets you shut off your home's water or gas supply from anywhere. Pair it with Alexa or Google Home for voice control, or use the Tuya app to monitor and act remotely.
Unlike basic shutoff valves, this device gives you real-time alerts. Imagine your basement floods in the middle of the night - the app sends a push notification before the water reaches the carpet. You can close the valve instantly, saving thousands in damage. It supports both Wi-Fi and Zigbee for flexible connectivity.
Installation takes minutes on existing valves. No plumbing skills needed. The motor rotates 90 degrees to open or close, handling standard ball valves. Whether you're checking on a rental property or securing your own home, this controller turns a passive valve into an active safeguard.
