How do the drip alerts work?

For Hall Effect sensors (3/4", 1" and 1.25" flow sensors), there is a feature available in the software called Drip alerts, designed to make the alerts much more sensitive to minuscule events. The algorithm for drip alerts detects when there are more tiny flow spikes (flows less than 0.5 litres per minute) than usual within a specific time window. These tiny spikes can be hard to see among larger flows but become noticeable when zoomed in on graphs. 

To enable drip alerts, you need to use Dynamic alerts and select the 'Drip detection' option during the learning process.

However, drip detection alone should not be solely relied upon as it takes longer to detect leaks due to the tiny volumes involved. Wireless splash sensors or leak cables are considered the best way to catch drips.
