Viewing Sensor Data for a Location

The second section of the Mobile App Dashboard is for Sensors. This section only appears if your organization has implemented the Temperature Monitoring System.

Sensor Grid

Sensor information is presented as cards in a Grid format:

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 tap on the chart at any point to show the reading taken at that point on the chart.

  

• You can place two fingers at any point on the chart, and spread them left and right to zoom in:

  

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

Sensor Information and Status

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

• At the top 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.
• Below the chart 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 below the minimum or above the maximum could trigger an alert.

• Below the temperature range minimum and maximum 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 articles in the Sensor Batteries section.

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 made 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 tell you if notifications can be sent out if an alert occurs (pause button) or if they have been paused (play button):

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

If these icons are disabled in the Mobile App, it means the system has not been configured to enable pausing and resuming of sensor alert notifications through the Mobile App.

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.
