CHAPTER 1: HEADLINE
CHAPTER 6: MQTT MONITORING
At this stage you should have three files:
spxclient.key
client.crt and
mosquitto.org.crt.
Additional steps are necessary to create the .PEM certificate files that can be uploaded on the Gateway.
To prepare the test .PEM certificate files:
1. Open the file spxclient.key with Notepad++.
2. Go to the end of the file, and copy and paste the contents of client.crt just below it. Now you should have a file
with the private key and certificate combined.
Save the file, using spxtest.pem as the filename.
3.
Rename the file mosquitto.org.crt and use mosquitto.org.pem as the new filename.
4.
Now you should have two files which can be uploaded to the Gateway:
spxtest.pem (client certificate) and
mosquitto.org.pem (server certificate).
To set up MQTTS on the AlertWerks Plus Gateway, you need to configure the MQTTS settings.
To configure these settings:
1. Click on Enable MQTT.
2. Click on Broadcast sensor values periodically and set it to a 1 minute interval.
Click on Use SSL to enable MQTTS.
3.
(optional) Click on Verify peer certificate to enable the certificate verification.
4.
5. After you browse to the file spxtest.pem, click on the Upload button to upload the client certificate.
6. After you browse to the file mosquitto.org.pem, click on the Upload button to upload the server certificate.
NOTE: You should see two green popup messages indicating that the certificate files have been uploaded
successfully. If you don't see these messages, there is a problem with the .PEM certificate files, and you should try
to create them again.
