Bob,
Since you have a lot of fields that you want to ignore, try setting the
ignore flag to true at the 'topic' level. Also I don’t think you want to
set contains_total. So you would end up with something like this,
[[topics]]
[[[application/18/device/2cf7f12122500013/rx]]]
ignore = true
[[[[CO2_Value_PPM]]]]
name = co2
ignore = false
Since the data is published so infrequently, once you get the basic
configuration working, you might want to look into the expires_after
option. This will cache the value between publications. For additional
information see,
