Frizzlife LP365-P

The LP365-P is sold in a 1" NPT version that includes 3/4" adapters (1" & 3/4") and in a 1-1/4" version (1" & 1-1/4").

Patented ultrasonic flow sensing with no moving parts, over a 0.001 to 18 GPM monitoring range, plus pipeline pressure on this version.

Detects flow changes down to 0.01 GPM and has an in-app Leak Test that checks the line while every fixture is off.

The manual says that even when unplugged it keeps monitoring and can shut off the valve automatically on its internal battery, with the app used only for remote control.

The LP365 has no leak sensor input; Frizzlife's wireless leak sensors are sold only with the separate LPG365 kit and are not compatible with the LP365.

The pressure version replaces the pipeline temperature reading with pressure, so it has no temperature data to warn about freezing.

Customized protection modes (auto or advanced) and a protection timer that pauses monitoring during scheduled heavy use such as irrigation; Amazon also lists linking with other smart devices.

Frizzlife's own app and Smart Life both run on Tuya's cloud, and Home Assistant owners report reading the valve and flow data through it: Amazon reviewers say they integrated it into their Home Assistant setup and plot usage there. No Frizzlife-specific integration is listed.

Frizzlife sells it as a Wi-Fi device paired through the Frizzlife app (or Smart Life) but does not publish which Wi-Fi band it uses.

Plugs into an AC outlet through a power adapter with a 6.5 ft cable; the unit must be plugged in to connect to the app.

The store lists a lithium-ion battery cell; it is a rechargeable internal pack charged from the power adapter, not user-replaced cells.

Up to 4 to 6 months of standby on a full charge, depending on usage, network and environment.

When unplugged it runs on its internal battery, keeps monitoring water use and can still shut off the valve automatically; the app is only for remote control.
