Create New Threshold Alarm
A threshold alarm is an alarm that triggers if usage exceeds or falls below a defined threshold for a given reference period. You create new alarms and manage your threshold alarms via the Manage Alarms tool.
A threshold alarm can be created for a property, a building, or a meter. If created for a property or building, the same aggregation rules apply as in the reports — that is, energy series for main meters are used, and if no main meter exists for the energy type, sub-meter series are used instead.
To create a new alarm, the following information needs to be filled in.
- Choose a name for your alarm. This name will appear in the list of all alarms in the Manage Alarms view.
- Each alarm can have one quantity, but multiple usage types if desired. If your alarm has more than one usage type, data from all usage types is summed, and it is that data series on which the alarm will be calculated to check whether the threshold has been exceeded or fallen below.
- The resolution for threshold alarms is hourly, daily, or monthly.
- Next, define whether you want the alarm to trigger if the threshold is exceeded or fallen below your specified threshold value.
- Enter your desired threshold value.
- If you want to add time conditions for your alarm, you do so next. Further down in this article we describe the time conditions in more detail.
- Alarm levels are a way for you to categorize how critical the alarms are, where you can choose between Information, Warning, and Critical. These levels can then be filtered on in the Manage Alarms tool.
When you enter your threshold value, a visualization appears showing you where your threshold sits relative to incoming data over the past year. You will also be told how many times this threshold would have triggered the alarm over the last 12 months. Neat, right?
Time Interval for Threshold Alarms
It is possible to define a time interval for a threshold alarm. This means you can have an alarm that is only active during certain months of the year, certain days of the week, or certain times of the day. The time interval is configured when you create the alarm.
Below is an example of an alarm that is only active during winter, on weekdays, and between 22:00 and 06:00. Note that if your time interval crosses midnight, two intervals need to be set — one from 00 and another to 24.
