Your service is binding to *archive records*, so you're only going to see evapcoolerdelta in the records (marked with "REC"), not the LOOP packets. Let it run longer and see what is in the records.
However, on the basis of the little snipped you posted, I can predict what the problem is: there are no LOOP packets with outTemp. You need both outTemp and extraTemp2 to calculate evapcoolerdelta. So, it never gets calculated. -tk On Tue, Aug 4, 2020 at 3:49 PM Kevin Key <[email protected]> wrote: > It turns out I had to stop the regular weewx service first - then I was > able to get weewxd to display the output.
