There are 3 alert categories: · Permanent - active 24/7. · Dynamic - changes based on the time of day and day of the week, learnt from your consumption history. · Holiday - exceptions which override any other setting and can be used to force a low threshold (if you are away), or force a high threshold (if you predict a spike).
Each alarm category has a 2 stage process: ‘Alert’ and ‘Shut off’ which is specified using a time and volume of water to be consumed before an alarm is raised. Both alarms will send a notification by email and/or SMS (based on your preferences in user settings).
· Exceeding the ‘Alert’ threshold triggers a Minor Alert which sends a notification.
· Exceeding the ‘Shut Off’ threshold triggers a Major Alert which sends another notification, and (optionally) turns the water off.
As an example of a simple alarm, here is a situation where the flow of water begins at 17:30 and the thresholds are
· Alert threshold = 30 minutes or 60 litres
· Shut off threshold = 2 hours or 240 litres
Note that no alarm is set by default when a device is first installed, to give time for history to be built up and learnt. However, alarms can be created and modified remotely at any time.
After 1 week, “dynamic thresholds” can learn from your past water consumption, which will record your unique water profile for any area of the building you monitor.
