I looked more closely at the payload format and I don't think that format
is currently supported. specifically the 'nested array'..
"object":{"err":0,"messages":[{"CO2_Value_PPM":433,"measurementId":4100,"type":"report_telemetry"}]
Busy time of the year, so not sure when I'll have time to delve into a
solution.
