HaozeeWiFi Smart Water Valve and Automatic Shutoff, Flow Meter, Automation Scene Works with Leak Detector, Built-in Rechargeable Battery, for DN20 3/4-Inch Diameter Pipe

So far so good. Easy install, no leaks. There is a battery backup, but it shuts off the wifi connection if it doesnt have a source of power. The battery allows you to open/close the valve with the button directly on the device.

So far so good. It does need a ups though because if power is lost, the wifi settings are lost.Overall great device to help manage and watch water flow or disable the water flow.

Jury is out wrt whether or not it works as it is supposed to. I bought it to protect against a pipe bursting in my basement. I hope I never have the occasion to test it but it does give peace of mind anyway. I love the features it is supposed to have though. BUT... and the reason for 3 stars is than it is difficult to know how to set it up. 18 pages of instructions are printed on one piece of paper 20" x 6" with a Font size of 4. I could not read them with my reading glasses. I had to use a magnifying glass. Also, I still am not sure if it will communicate with me when I am away outside the range of Bluetooth.I thought that 3/4" connection meant that it would directly connect to a 3/4 SharkBite fitting but it does not. You have to use the extenders that come with itI think I saw the word "Network" in the instructions but I am too exhausted to pursue after struggling through the Bluetooth setup.

Unit is sturdy in your hands. Tested before installing. Includes brass couplings and wire and rechargeable battery power what a plus. Now I can monitor and turn off valve through WiFi where ever I am. Just finished install myself and all is good so far. Will only update review if i have a problem with unit.

I ordered the Haozee WiFi Smart Water Valve for the main water pipe entering my garage. Its WiFi connectivity and leak detector integration seemed ideal for monitoring water flow at home.Setup was straightforward, connecting easily to my 3/4-inch pipe with basic plumbing tools. The Smart Life app linked quickly, showing real-time water usage and valve status. It responds promptly to manual controls and pairs well with my leak sensors for automatic shutoff.The built-in battery keeps it online during power outages. For the price, this valve provides reliable automation and peace of mind for water management.

It's winter time here in Colorado so I haven't got a chance to use this but I did give it a test and it seems to function great packaged well with decent instructions this auto work really great for my summer garden.

It's fairly easy to use. Great for turning water on and off. The design is great. Great price for this product.
