Azure IoT Central device template issue

Question

I`m trying to get data from meters through "TheThingsNetwork". To analyse my data, i would like to see them in MS Azure IoT Central. The meters are sending their payload to my ToT Central application. When i try to build an automatic device template, the whole payload is shown in "unmodeled data". unmodled data Can somebody help me to fix that issue?

This is my Payload:

Answer 1

You should use the mapping telemetry data on ingress, see more details here.

Based on your payload and the device model, the raw data will be the following:

Note, that I had to remove your component CMI4160_537 from the device model for test purpose.
