I want to use that device with Ignition SCADA via MQTT. I have read through the sensor user guide but still require further assistance when applying the settings to Ignition. I believe that my wifi configuration, on the ncd gateway, is correct because I get a solid white light but I am unsure of the MQTT settings. I am using the engine and distributor module on Ignition so I believe I am using the wrong URL/IP for my MQTT broker and potentially, the username and client ID. I may also be screwing everything up entirely because I just began learning about MQTT and Ignition a couple of weeks ago.
It sounds like the device has connected to WiFi but is unable to connect to the MQTT Broker.
I would highly recommend troubleshooting the connection to the MQTT Broker on your computer using MQTT Explorer here:
Using MQTT Explorer enter the host URL or IP, the port number, credentials, and Client ID. Once you are able to connect to the broker using MQTT Explorer enter the same into the device and see if it is able to connect.
One other thing I have seen in the past. If you are on a corporate IT managed network sometimes firewalls will block outgoing connections over the common MQTT protocol ports(1883 and 8883). I would confirm that is not blocked.
I took your advice by downloaded MQTT Explorer to test connection and fixed the firewall settings to allow MQTT port connections. I was successfully able to pub/sub between my server and the MQTT Explorer client but am still unsuccessful in making a connection between the device and my server. The diagnostic log on Ignition says that it failed to authenticate due to a bad username and/or password so I am currently confused after those same credentials worked when connecting to the MQTT Explorer client. Any advice?
