[weewx-user] Re: extension to calculate rainstorm info: total rainfall, ending time, duration

2018-04-07 Thread 'Rich Altmaier' via weewx-user 
I have an update, storm v1.1.  I misunderstood the timestamp on archive 
records.  I now see the timestamp value is the time at end of the interval 
of rain accumulation.  Fixed that!   
Rich

storm.py  v1.1

This search list extension calculates tags, one is a time interval,
 and one is a duration, of the most recent rainstorm:

'last_rain_storm': finds the last rain interval, allowing stats to
   be calculated over that interval.
 We search back to find the storm end, which might be still on-going,
 and search still further back to find the rain start (after a dry period)
'storm_duration':  duration in days

***
Usage:
 1) copy this file to the user directory
/usr/share/weewx/user

 2) add the option search_list_extensions in the 
   /etc/weewx/skins/Standard/skin.conf configuration file, 
   adding the name of this extension.  When you're done, 
   it will look  like this:

 [CheetahGenerator]
search_list_extensions = user.storm.RainStorm

 3) in the html template /etc/weewx/skins/Standard/index.html.tmpl
in the Current Conditions section, perhaps after Inside Temperature,
add this table row:
   
  last storm total rain,
  ending $last_rain_storm.end
  of duration $storm_duration days
  $last_rain_storm.rain.sum
   

You can also use other tags such as $last_rain_storm.outTemp.max for the max
temperature, or $last_rain_storm.rain.sum for the total rainfall in the last
storm
