Smart RV water monitoring system that combines continuous flow monitoring with wireless leak sensors, automatically shutting off the water supply the moment a leak is detected. Controlled through the Blu Onyx™ mobile app or an included wireless remote.
The WATERSTOP™ by Blu Technology is a patent-pending mobile water monitoring solution built around an automatic shut-off valve, designed to stop small leaks before they become costly repairs. It combines continuous flow monitoring with wireless leak sensors, so if even a small drop of water touches a sensor, the system's Blu Onyx™ intelligent software sends an instant alert and automatically shuts off the RV's water supply.
One wireless flood sensor is included and can be placed in a high-risk area such as under the sink, near the toilet, or in the utility bay. WATERSTOP™ can simultaneously monitor up to seven leak sensors for expanded coverage, with additional sensors available separately. Beyond leak protection, the system also tracks water usage and flow rate, and sends alerts when your RV's water filters reach the end of their service life.
Valve automatically shuts off the water supply the instant a connected leak sensor detects moisture
Monitor and control water on/off status through the Blu Onyx™ app or an included wireless remote
Continuous flow monitoring detects sudden bursts while tracking water consumption and usage time
Get notified through the app when your RV's water filtration system reaches the end of its service life
Leak sensors cannot operate independently - they require the WATERSTOP™ unit to function. The system ships with one wireless leak sensor included, and can simultaneously monitor up to seven sensors total for expanded coverage across multiple risk areas (under sinks, near the toilet, utility bay, and similar spots).
The Blu Onyx™ app is required to set up and get the most out of WATERSTOP™, including real-time leak alerts, remote water control, flow rate and usage tracking, and filter life reminders. Download on the Apple App Store Download on Google Play
