Setting Custom Notifications for Commercial Refrigeration

Keywords: notifications, refrigeration


Monnit has created a custom sensor notification that is frequently used in commercial refrigeration monitoring. This custom notification allows you to receive an alert when the temperature has changed for a set amount of time instead of sending the alert based on a single reading. This helps prevent false alerts in commercial refrigeration applications.

To setup the alert in iMonnit, follow these instructions; 

In order to use this custom alert, first make sure that the "Aware State" settings are correct on the temperature sensor(s) you will be using.

Set Sensor Aware State

To set the "Aware State" settings, click on the name of the temperature sensor in the sensor list then click the "Edit" tab, or simply click the pencil icon next to the sensor name in the sensor list.

From the sensor edit page, we need to make sure that the "Aware State" settings will work for our notification. For iMonnit Premiere accounts, you can set the aware state heartbeat to as quick as 10 minutes, if using the basic "free" monitoring, this defaults to your standard heartbeat.

Next we need to set the "Use Aware State" setting. This is a threshold that is held in the sensors physical memory, triggering communication when it is met. For Premiere the sensor can hold a high and low threshold, for basic, the sensor will hold one threshold.

Temperature Sensor - Aware State Settings

With these few things set, we are now ready to create our notification.

Set Custom Notification

To set up a customer refrigeration notification, click the "Notifications" tab in the blue navigation bar. At the top right of the notifications page, click the "Add Notification" button.

Add Notification

Click the "Advanced Notification" button, then choose "Notify after aware period" as the type of advaned notification.

Notify After Aware

On the next screen, set the notification parameters by entering your custom notification text and setting the "Alert After" time equal to the time your sensor can stay in the alert state prior to sending the notification.

If you want the notification to be active 24 hours a day, leave the "Schedule Notification Times" setting on "Always", or to set it to specific times of the day, change the schedule there. Set your snooze period and make sure the "Notification is active" box is checked and clcik "Continue".

Parameters NAA

Next, from the box on the left, choose the sensor(s) you would like to assign this notification and move them to the box on the right by clicking the checkbox next to each sensor and then clicking the double arrows in between the two boxes. This will move the sensors to the box on the right. 

Assign Sensor

Last, click the "People to Notify" tab and choose the recipients of the notification in the same way. 

This notification will automatically use the settings from each of the assigned sensors, to let you know when the temperature has been above or below the individual sensors' aware state threshold for the defined amount of time.

If you are familiar with more Monnit sensor types, you realize that this notification can be used by several other sensor profiles. For instance, instead of being notified when a door is opened, be notified when a door is left open... there are a plethora of possibilities.
