Hi All, been submitting to wunderground for some time with pywws and a
wh-1080 running on my openwrt router, but it was intermittent with various
issues (in the station) so have upgraded to WMR200 and have switched over
here to weewx.
Ill be writing up a guide about the steps i followed to get it all
installed and working, and post a link in this thread.
To start with i wanted to bring something up to see if its just me on
opnwrt and a minimal python or a wider bug/limitation of wmr200.
So i mainly use my setup for posting to wunderground, and they only keep
data down to 5 min interval, so no point submitting it any more frequently.
The default archive interval of the wmr200 is 1 minute, and the default
setting in weewxd config is 5 mins (300 seconds)
The behavior of weewx is to preference the station "hardware" setting over
the config file setting, with a startup log message something like this:
"The archive interval in the configuration file (300) does not match the
station hardware interval (60)."
"Using archive interval of 60 seconds (specified by hardware)"
This is all fine and well, but the problem is when i went and changed the
station interval to 5 mins, *weewxd still "detects" and reports that its
set at 60 seconds, *i even tried clearing the station archive data and
weewx database.
So i tried tracking down the code in the source that reads out the archive
interval setting, and got as close as this code in wmr200.py driver:
# Archive interval in seconds.
self._archive_interval = int(stn_dict.get('archive_interval', 60))
if self._archive_interval not in [60, 300]:
logwar('Unverified archive interval:%d sec'
% self._archive_interval)
I tried to find out what *stn_dict.get *does but could not track it down,
so not sure if the '60' argument is a default or override, and how it
interacts with the actual station setting if it is or can read it ?
As setting it to 300, makes the driver report that the interval setting is
300 seconds (5 mins)
Any thoughts ???
Thanks.
