We’ve had the “mi agua” monitor for almost 2 years and we’ve so far been alerted 3 times about our water usage. The first alert was just after the installation that detected continuous usage hence a water leak. It was on the main line coming into the house. The second alert turned out to be a leaking toliet seal and the third was the poolman leaving y hose on. The app is easy to use too and we have peace of mind that we won’t have an excessive water bill. The water company doesn’t care if you have a leak that could cost thousands in Javea.
