      I'm having a hard time retrieving data from a MQTT JSON payload and placing the information in a datapoint. I am able to connect to the MQTT broker and subscribe to the Topic. The playload data is coming through correctly, but I can't figure out the nomenclature to get the information into the datapoint. Any help would be greatly appreciated.

        @Curtis the input is in JSON Pointer notation. Slashes are the separator, you can learn more here: https://www.baeldung.com/json-pointer or the full monty here: https://www.rfc-editor.org/rfc/rfc6901.html (with some decent examples)

          Your value JSON pointer would look like this:

          /values/0/v
