Rainy days greater than 1mm

[Chris Davies-Barnard]

Evening all,

From the http://www.weewx.com/docs/customizing.htm#aggregation_types page I believe the following should work for months with equivalents working for weeks and years.

$month.rain.sum_ge(1.0)

and thus provide me with a value comparable to the MET Office Climate Averages.

https://www.metoffice.gov.uk/research/climate/maps-and-data

but at the moment I'll getting an error:

Sep 28 20:05:44 pecan-ubuntu wee_reports[30045] ERROR weewx.cheetahgenerator: ****    File "/home/weewx/bin/weewx/tags.py", line 326, in sum_ge

Sep 28 20:05:44 pecan-ubuntu wee_reports[30045] ERROR weewx.cheetahgenerator: ****  TypeError: object of type 'float' has no len()

and a different error if I wrap 1.0 in quotes.

How am I getting this wrong?

The aggregate type sum_ge() actually takes a ValueTuple as an argument, not a single float. As a convenience, for some types, it can be shortened to a 2-way tuple. So, you want

$month.rain.sum_ge((1.0, 'mm'))

Thanks Tom.  

Should I have been able to glean this from the documentation?

If not, could the documentation be updated to show the inputs required?  Something in keeping with or similar to the main Python documentation.

Thanks again for the excellent support.

Yes, it should be possible. Unfortunately, there's not much documentation about aggregations taking a value, and what little there is, is wrong!
