I have gone through the documentation to bring tags from a custom namespace via flat MQTT using the JSON decoder which works well so far. I am able to create the folder structure of my topic automatically and it builds my tags as needed.
Does the functionality exist to instruct the tags to be inserted into a pre-defined UDT? Im not looking to build a UDT as it would with the SparkplugB however it would be nice to take some MQTT sensor data and drop it right into a UDT definition.
Thanks in advance.
Did you get anywhere with this? I have a number of custom sensors that publish MQTT json output. These work fine but I thought it would be better to create a UDT for them so I can configure alarms once instead of individually. I'm using Maker Edition and when I right-click on a parent and attempt to make a UDT I get an error message: [MQTT_Engine]types/Name = Bad_AccessDenied("Insufficient Tag Provider Edit Permissions") yet I can't see any way to edit permissions on the MQTT engine.
One pattern that you could probably leverage here is to create your UDTs in a standard tag provider. Within those UDTs, you can have reference tags that indirect over to the tag paths under [MQTT Engine] provider. This is the strategy I use in my Maker gateway to convert some of the plain MQTT payloads from my The Things Network (TTN) LoRaWAN sensors into objects for use in Ignition.
Hi Mike, I'm having the same problem, did you manage to find a solution?
