When aggregate = individual, I am expecting it to NOT send in JSON format, and instead send it just the individual metric to the topic of /weewx/<mesurement>. I believe that is how yours is working today. If we want to test with your instance, you can add -v to your mosquitto_sub query and that will then show us the individual topics that are underneath the topic of "weather" and that likely each measurement is a different subtopic.
When weewx sends the JSON string, I am utilizing the loop bindings. With loop bindings, the JSON strings will differ with each transmission since it doesn't get everything on every reading. As a result of this, it makes it rather difficult for my other application to interpret these JSON strings since each one is different and not consistent. Other options will include defaulting back to archive bindings, but they aren't real time enough for my application. If I do that, the JSON string should be mostly uniform each time the archive runs. But once again, if I select "individual" measurements when doing archive, I have the same issue, where it will only parse the first reading of the JSON string. So instead I have to use "aggregate" and parse the JSON string again, back to square one, but at least now the JSON string should be a little more uniform. Overall I am pushing these measurements into MQTT so that I can set them up as sensors within my home automation platform. I can probably do some hackery to make my home automation platform properly decipher the JSON if I need to. But overall this smells like a bug or configuration issue within the MQTT extension for WeeWX.
