Navigate to the Alerts tab. Tap on Alert Channels and create a channel.
Tap on the gear icon next to the alert channel and go to Manage Alert Channel Notifications to set your personal preferences for receiving an alert from this channel (Go to Managing Alert Channel for details). Note that to receive a text message, you should verify your phone number first, which can be done in the Profile Button on the top right side of the screen.
Ensure your device is connected to the cloud by checking if you see the green light on the device page, Enable the Node-RED connection in the Remote Connections tab, and hit Connect.
From the nodes in the left navigation bar, drag and drop the alert channel out node.
Double-click on the alert channel out node, and then double click on the edit button.
If you have previously configured any nodes with your Device API KEY username and password, your nodes should already be configured.
Next, we will click the refresh button in the Topic and select the Alert Channel that we will like to publish to.
Once everything is complete, click Done.
