  • Alarm - all alarms you have received will be presented in the list

The additional alarm feature includes severity levels of the alarms (alert , critical , error ).
When you filter out the alarms, Message type column will display symbols of alarm severity levels.

From/To: Helps you filter out the messages received by date.

  • When you click on a drop-down arrow, the calendar opens
  • Choose exact dates (from/to) of the messages you would like to be displayed
  • Messages will be displayed on the page


Search bar helps you search through the messages by their sources/sensors (e.g. living room, elevator), message text and descriptions (e.g. high temperature, humidity…) if you start typing any part of these three components (e.g. high instead of humidity high).

If you want to clear filtering, and go back to default view, click on the x button in the filter search bar.


To sort messages according to date, source, message type, message or description:

  • Click the arrow next to the column name (the arrow appears if you hover over column name)
