I tried changing $current.co2 to $last.co2 but it only printed "$last.co2" on the web page.
Adding the [Accumulator] section to weewx.conf only caused an error and exit when I restarted weewx. I tried adding this in several places but none seems to let weewx restart without an exit error. Is there a special place to add this? Couldn't find anything in the doc about placement.
