Maestro Home Automation Protection System

The QMI Maestro system is the most advanced, patented, water leak, earthquake, gas leak detection, and automatic shutoff system in the market today.

Click here for Press Release.


The system features modern, state-of-the-art technology with old-fashioned pricing.  It is a network-enabled system that will shut down the appropriate valve whenever a sensor detects a leak.  The gas valve will shut whenever a gas sensor detects gas, the water valve will shut whenever a water sensor detects water, and both valves will shut when the earthquake sensor detects an earthquake.

This low-cost, high-tech system is very easy to install.  It is a state-of-the-art modular system with all components communicating wirelessly to the controller.  This custom 2-way RF system provides a secure, reliable communication between the controller, valves, and sensors.

A liquid crystal display on the controller allows you to monitor each sensor individually.  If a sensor detects a problem, the display clearly tells you which sensor has detected the problem and what the problem is.


With the Network Gateway connected to your existing internet connection, the Maestro system will send out an email alert any time there is a water leak, gas leak, or if any sensor or valve reports a low-battery condition.

QMI has been working closely with insurance companies to offer rebates or discounts to customers who have a  QMI shutoff system installed.  Contact your insurance provider for more information.
