How do I add and manage alarms?

Alarms notify you when a sensor reading goes outside of its expected range, so you can act quickly before a problem escalates.

Step 1: Go to Alarm Thresholds

In the side menu, click "System Setup", then select "Alarm Thresholds".

Step 2: Find your sensor

You'll see a list of all your sensors. Use the search bar to find the one you want to set an alarm for.

Step 3: Configure the alarm

Next to your sensor, fill in the following:

Day start/end times - set what counts as "day". Anything outside these hours is treated as "night".
Day and night thresholds - set the minimum and maximum limits. If a reading goes outside these, an alarm triggers.
Delay (mins) - how long a reading can be out of range before an alarm fires. For example, a 30-minute delay means a brief dip won't trigger an alert if it recovers in time.
Warning % - an early warning before the alarm triggers. For example, 10% means alerts go out when the sensor is getting close to the limit.
Healthy state - tick this to automatically clear an alarm once readings return to normal.
Enabled - tick this to activate the alarm. Stakeholders will then receive alerts if it triggers.
Offline alert - set how many hours of no signal before an alert fires. You can set a default for the whole system under "System Offline Delay", or choose a different time per sensor.

Click Save all when done.

Step 4: Export and audit

Export your alarm setup using the PDF or Excel buttons.
All changes are automatically logged, including who made them and when. This is useful for audits.
To view sensors across different sites, use the dropdown at the top of the page to switch between systems.
