Windy plugin error

[raenrfm]

Posting to windy works for a while but then I inevitably get this error:

Is it because I'm getting a null entry for pressure in a given archive cycle?

[raenrfm]

Seems like it's this line in the windy.py:

if 'barometer' in record_m:

data['pressure'] = 100.0 * record_m['barometer'] # Pascals

that is causing the issue, but there is no mqtt topic in my setup called "barometer", I'm only posting "pressure", so why would it even be trying to execute this function?

Any takers on this one?

Without looking at windy.py, my guess is there is something in your loop and/or archive content that 'has' a barometer item in there.

Hey Vince, thanks for the tip.  Turns out I needed to send from my base station the "barometer" value pre calculated in the base station before sending it to the mqtt server, so seeing as windy.py needs the barometer implicitly I had to send it to weewx already corrected for my altitude.  I guess I assumed that weewx would calculate it at the end of every archive cycle.  Weird.

it looks like 'barometer' is, indeed, in the record, but it has a value of 'None'.  does your station send partial packets, or does your station sometimes have no barometric reading in enough loop packets so that it reports an archive record with a value of 'None' for pressure/barometer/altimeter? 

fixed at commit add0332f89cd621f4dc9e49bbcd072698f22fbc4 - if there is no barometer, the weewx-windy extension will upload a value of None (not sure how windy will deal with this, but that is what happens for all of the other observations, so at least it will be consistent and will not crash weewx)
