How To Configure A Threshold Range For Your Room Alert Graph

In your Room Alert Account or in Room Alert Manager, you can display a highlighted range on your graphs to easily check if sensor readings fall within that range. You may choose to graph a pre-defined threshold range—including ASHRAE Data Center Recommendations and NWS Heat Index Risk Levels—or define your own custom range.

Follow these steps to create a custom threshold range:

1. Log in to your RoomAlert.com Account or Room Alert Manager.
   • You may sign into your Room Alert Account at https://account.roomalert.com/gateway
   • For instructions to access Room Alert Manager, please see our FAQ, How to Open Room Alert Manager’s Web Interface.

2. Select Guidance in the navigation bar to the left.
   
3. The Threshold Ranges tab will open by default.
   
   Here, you’ll see a list of pre-defined thresholds ranges, along with any custom ranges that were previously saved.
4. To configure a new range, select the New Threshold Range button.
   
5. The Threshold Range Form will open.
   
   • The default name is “New Threshold Range X,” but we’re renaming ours “Good Freezer Temps.”
   • In Choose Reading Type, select either Temperature, Humidity  or Custom.
   • In Choose Operator, select either is above, is below, is between or is not between.
   • Then enter the value(s) for your threshold or range. We’ve set our range from -40F to -10F.
6. When you’re done, select Save Changes.
   
7. Your new threshold range will appear in the list, as shown below.
   
   • Pre-defined threshold ranges are listed with a shield icon.
   • Custom threshold ranges are listed with a pencil icon.

Next steps

Now that you’ve saved a custom threshold range, you can graph it alongside your sensor data. When you go to the Sensor Data and Reports tab, you’ll see your new range populated in the Select Threshold Range drop-down menu, as shown below.
