Re: [weewx-user] Re: Vaisala WXT520 automatic mode
Thank you Matthew, that was a big help! :) Now, what I don't understand is why I get intermittently very high readings on wind and temperature. [image: Capture2.PNG] And, also what settings I should have on the sensor (Imperal or Metric): [image: Capture.PNG] On Wednesday, February 21, 2024 at 9:28:35 PM UTC+1 matthew wall wrote: > the failure in delta_rain has been fixed as of commit d64d397 and release > 0.7 of the wxt5x0 driver > > -- You received this message because you are subscribed to the Google Groups "weewx-user" group.

the failure in delta_rain has been fixed as of commit d64d397 and release 0.7 of the wxt5x0 driver -- You received this message because you are subscribed to the Google Groups "weewx-user" group.

Re: [weewx-user] Re: Vaisala WXT520 automatic mode
Yes, seems to be an old problem.
I wonder how people using a Vaisala WXT520 has made it work without
crashing.
The code, in the driver, that I think is an issue, is probably this,
however I am not a python programmer, so I have no idea how to fix it:
*537 @staticmethod538 def _delta_rain(rain, last_rain):
539 if last_rain is None:540 loginf("skipping rain
measurement of %s: no last rain" % rain)541 return None
542 if rain < last_rain:543 loginf("rain counter
wraparound detected: new=%s last=%s" %544(rain,
last_rain))545 return rain546 return rain -
last_rain*

Re: [weewx-user] Re: Vaisala WXT520 automatic mode
Looks like the author of the extension forgot to check whether the value of
"rain" could be None. This appears to be a known issue, but hasn't been
fixed. See https://github.com/matthewwall/weewx-wxt5x0/issues/8
