I'd go with something like...... [[topics]] [[[mytopic]]] [[[[CO2_Value_PPM]]]] name = co2 contains total = false conversion type = float [[[[measurementID]]]] ignore = true [[[[report_telemetry]]]] ignore = true
Define the topic to subscribe to. Do not ignore the one element therein that you want. Ignore the elements you don't want.
