Viewing Tripped Station or Sensor Alarms

In addition to any notifications you may receive or relay switches when an alarm trips, there are several ways to check if the station has any tripped alarms within HOBOlink. (For details on MX Gateway Alarms, see Monitoring Devices.)

  • Check for a tripped alarm icon in the Devices list.

  • The station or mote icon on the map will be red instead of blue if an alarm has tripped. Hover over the station or mote icon to see details about the type of alarm, such as a sensor error, low mote battery, missing wireless mote, the station has missed a connection, or a sensor alarm has tripped. See Tips for Working with Wireless Sensors for information about missing wireless motes.

  • Check for a tripped alarm icon with an arrow indicator next to a sensor in the latest conditions panel, on the map, or on the device overview page. The arrow indicator shows whether the sensor reading is above the threshold (up arrow) or below the threshold (down arrow), or outside the range (up and down arrow).
  • Look for red or blue shading on the device graph for the sensor with the tripped alarm. Red shading on the graph indicates the sensor reading was above the specified threshold while blue shading indicates the reading was below the threshold. Note: Graphs in dashboard widgets will not display this shading. However, you can set goal lines for line chart, bar chart, and area chart widgets. For example, if a sensor alarm is configured to trip when the temperature is above 32 degrees and you have a line chart widget set up for that sensor, you can set a goal line with a value of 32 for the widget. This will give you a visual representation of readings above the alarm threshold of 32 degrees. See Changing Widget Properties for details.
  • When configuring alarms, any tripped alarms are displayed in red.
  • Check the Alarms log for full details about the alarm, including whether it tripped or cleared, any notes, the sensor reading (if applicable), and the date and time the event occurred. To view the log, go to the Alarms page and click See All Alarm Logs or go to your device page, click Logs and then click Full log on the Alarms tab.

  • Set up an alarms widget in dashboards to show the number of sensor alarms that have tripped in the time frame selected. See Using Dashboards for details.

All alarms remain enabled when they trip or clear on RX3000 and RX2100 stations. On U30 stations, the Battery Low, Memory Low, and Sensor Failure alarms all are disabled as soon as one trips and must be re-enabled once the condition is resolved. See System Alarms for details.
