Viewing Sensor Data for a Location

The second section of the Server App Dashboard is for Sensors. This section only appears if your organization has implemented the Temperature Monitoring System and the active workspace is a location.

Sensor information is presented in one of two layouts:

• In a Grid layout, with each sensor represented by a card:

    

• In a List layout, with each sensor represented by a banner:

  

The default appearance of sensor date for a location is controlled by Configurations > Settings > Settings > Location Dashboard Settings:

• This setting can only be changed by a person with permission to change the default view.

You can then change the view while working with the dashboard by clicking on either the List or Grid button:

Sensor Grid View

Each sensor card shows the readings for a sensor during the last 24 hours as a chart:

The chart below the name shows the data collected over the past 24 hours:

• You can move your mouse pointer over the chart, then click, hold, drag the pointer either left or right, and release the pointer to zoom into the selected (shaded) area of the chart:

    

• To zoom back out to the 24-hour graph, click Reset zoom.

Sensor Information and Status

Each sensor card provides information about its sensor, as well as its status:

• At the top of each card is the name of the sensor.
  • If RESOLVE ALERT appears in red below the name, it means that a condition has occurred that caused an alert to be triggered. It needs to be resolved.
  • If Paused until [date] [time] appears at the top of the card, it means that alert notifications have been paused until the time has expired. The sensor continues to record temperatures, but no alerts will be issued until the pause expires or is lifted.
• Below the graph is a unique number that identifies the Device, and the Location where the device is installed:

  

  Both are links that, when clicked, take you to the Statistics > Sensors report:

  • Report Type is set to Sensor Readings.
  • Start Date and End Date are populated with the active date on the Dashboard.
  • Device Templates is populated with the template used when the sensor was setup.
• Below the Device identifier is Min. Temp, and below the Location name, is Max. Temp:

  

  These are the minimum and maximum temperatures of the range that is considered acceptable for the equipment to operate in. Values outside of this range could trigger an alert.

• Below the temperature range values are the status icons:

  

Battery Status

Battery status tells you if the batteries are fully charged (green), getting low (yellow), or needs replacing (red):

• If the battery icon is red, you need to immediately replace the battery.
• If the battery icon is yellow, you should get a new battery and have it available -- though we recommend replacing batteries even when they are yellow.

For more information on replacing batteries, see the Batteries section of this guide.

Connection Status

Connection status tells you if the wi-fi signal is strong (green), weak (yellow), or failing (red):

The signal icon on the sensor card is an indicator of the sensor's performance, which is identified by the color:

• A red icon means the sensor is at it's worst functional signal strength.  It will report a single reading every 15 minutes if received by the gateway and backlog pulls are not possible.  
• A yellow icon means the sensor can work as intended with temperature readings every 15 minutes and backlog pulls are possible.  However, if the environment changes in any way it could degrade to red.
• A green icon means the signal between the sensor and the gateway is good, temperature readings are taken every 15 minutes, backlog pulls are possible, and that data is being successfully transmitted.

Transmission of data to the server occurs every 20 minutes.

Obviously, the desired condition would be a green signal for all sensors. To resolve the issue where the signal is not green, you need to carry out one or more of the following:

• Make sure there is nothing near the gateway that could block the signal from the sensors.
• Make sure there is nothing near the sensors that could block the signal to the gateway.
• Move the gateway closer to where the sensors with a yellow or red icon are located, making sure not to weaken the signal from sensors that have a green icon.
• Add another gateway closer to where the sensors with a yellow or red icon are located.

Alert Notification Status

Alert Notifications status status tell you if notifications can be sent out (pause icon) or if they have been paused (resume icon):

• Click the pause icon, complete the dialog that appears, and the alert notifications are paused for a specific amount of time.
• Click the resume icon, complete the dialog that appears, and alert notifications are resumed, as needed.

For more information, Pausing and Resuming Sensor Alert Notifications in this guide.

Sensor List View

Each sensor banner shows the readings for a sensor during the last 24 hours as a graph:

• On the left side of each banner is the name of the Template used to set up the sensor: 
  • If RESOLVE ALERT appears in red below the name, it means that a condition has occurred that caused an alert to be triggered. It needs to be resolved.
  • If Paused until [date] [time] appears along the top of the banner, it means that alert notifications have been paused until the time has expired. The sensor continues to record temperatures, but no alerts will be issued until the pause expires or is lifted.
• To the right of the Template name is a unique number that identifies the Sensor:

  

  This is a link that, when clicked, take you to the Statistics > Sensors report:

  • Report Type is set to Sensor Readings.
  • Start Date and End Date are populated with the active date on the Dashboard.
  • Device Templates is populated with the template used when the sensor was setup.
• To the right of the sensor link is the chart that shows the data collected over the past 24 hours:
  
  • You can move your mouse pointer over the graph, click, hold, and drag the pointer either left or right, then release the pointer to zoom into the selected (shaded) area of the graph:

    

    

    To zoom back out to the 24-hour graph, click Reset zoom.
• To the right of the chart are the Min Max values:

  

  These are the minimum and maximum temperatures of the range that is considered acceptable for the equipment to operate in. Values outside of this range could trigger an alert.

• Next to the Min Max values are the status icons:

  

  • Battery status tells you if the batteries are fully charged (green), getting low (yellow), or needs replacing (red):

         

    • If the battery icon is red, you need to immediately replace the battery.
    • If the battery icon is yellow, you should get a new battery and have it available -- though we recommend replacing batteries even when they are yellow.

What is sensor backlog?

When a sensor cannot send data it has collected (readings) to the gateway for transmission to the server, it stores the data on the sensor -- referred to as a backlog. When communications between the sensor and the gateway is re-established with an acceptable strength, the backlog is transmitted to the server.
