LifeInnov WiFi Smart Water Valve, 3/4" NPT Shut-Off, Ultrasonic Flow, Tuya App

Know what your water is doing — and shut it off from anywhere

A Main Line That Finally Reports to You
The LifeInnov WiFi Smart Water Valve threads onto your 3/4" main supply line and makes it do something it has never done: speak up. Ultrasonic sensors—no spinning parts to clog or wear—read flow rate, water speed, and temperature in real time. The on-board LCD shows it at the pipe; the Tuya / Smart Life app carries it to wherever you are. And when something looks wrong, one tap closes the line.

No. It connects directly to your 2.4GHz or 5GHz home WiFi network.

Six things: your pipe size and connection type, water pressure range, a nearby power outlet, 2.4GHz or 5GHz WiFi coverage at the install spot, Bluetooth 5.0 on your phone for pairing, and an indoor installation location.

3/4" DN20 with standard NPT threading, the most common size for US residential water lines.
