In addition to showing the metrics, Radar can alert you by sending threshold desktop notifications. It can be helpful when you want to know as soon as things change with the metrics you track with Radar.
For example, you can set Radar to send a desktop notification when the Bitcoin price goes below $45,000 so that you can waste no item buying the dip.
Click on the pencil icon next to a metric and then select 'Next'. Now, set an auto-refresh interval without which you can't enable notifications. Check 'Show threshold notifications' and select 'Next'.
Notifications trigger in the auto-refresh interval when needed. You can use one of the two ways to trigger the notifications.
When installing from a 1-click installer, you can decide when the notification should be triggered (Work in progress. For now, you can edit the API and enable notifications). Three modes are supported. Greater than, less than and equals to.
When you select greater or less than, the primary/secondary value's numerical value is taken and compared with the threshold value you give. If the condition is satisfied, a notification will be shown.
Now, you can write your logic to trigger the notification. You have access to the API data, primaryValue & secondaryValue.
When you don't want to get notifications temporarily in a time range, you can snooze all notifications or notifications for a specific API. Right-click the Radar icon, select "Snooze Notifications".
