Well, until I read your message I'd never heard of pwsweather.com. I
couldn't find any details of the API on their website, but if it's
similar to the other 'services' supported by toservice.py then it should
be easy to add.

It is difficult to find a good description of the API, but I found this today:

http://macweather.net/viewtopic.php?f=12&t=398

I think the idea is that one does a 'POST' to a particular web address with account/password and weather data embedded in the URL, similar to this:

http://www.pwsweather.com/pwsupdate/pwsupdate.php?ID=STATIONID&PASSWORD=password&dateutc=2000-12-01+15%3A20%3A01&winddir=225&windspeedmph=0.0&windgustmph=0.0&tempf=34.88&rainin=0.06&dailyrainin=0.06&monthrainin=1.02&yearrainin=18.26&baromin=29.49&dewptf=30.16&humidity=83&weather=OVC&solarradiation=183&UV=5.28&softwaretype=Examplever1.1&action=updateraw

My own experience with 'talking' to these weather sites has been very primitive i.e. creating a text file and FTPing it to a site.  Although I understand the concept of a 'POST', I have no idea if this is more 'typical' a way to do this.

This looks *very* similar to Weather Underground's upload syntax, which
seems to have a lot of imitators. I suspect all you need to do is copy
the Weather Underground files (in pywws/services). You might need to set
'rapidfire' to False in the .ini file.

I think you are correct!

Initially I got some confusing results, but after deactivating my old PWSWeather station and creating a new one, I think it is working with minimal fuss:

Dare's WH2081 Station on PWSWeather

Hopefully it will help others to see this thread and wish to connect to their services as well :)

Thanks!

Well, I think there were just two parts to getting my pywws system to work with the PWS service (which I had already been using with my previous station/software).  This really isn't a 'tutorial', since I am assuming that you already have pywws up-and-running and just want to add the 'PWS' service to the other services you already use.

1) Make an 'ini' file for PWS service (i.e. 'pwsweather.ini'), modelled after 'underground.ini':

[config]
url        = http://www.pwsweather.com/pwsupdate/pwsupdate.php
#url-rf        = http://rtupdate.wunderground.com/weatherstation/updateweatherstation.php
catchup        = 0
rapidfire    = False
use get        = True
result        = ['success$']

[fixed]
action        = updateraw
softwaretype    = pywws
ID        = mystationid
PASSWORD    = mypassword

[fixed-rf]
realtime    = 1
rtfreq        = 48

2) Create a 'template' file for PWS service (i.e. 'pwsweather_template_1080.txt'), modelled after 'underground_template_1080.txt':

#live#
{
#idx          "'dateutc'      : '%Y-%m-%d %H:%M:%S',"#
#wind_dir     "'winddir'      : '%.0f'," "" "winddir_degrees(x)"#
#wind_ave     "'windspeedmph' : '%.2f'," "" "wind_mph(x)"#
#wind_gust    "'windgustmph'  : '%.2f'," "" "wind_mph(x)"#
#hum_out      "'humidity'     : '%.d',"#
#temp_out     "'tempf'        : '%.1f'," "" "temp_f(x)"#
#rel_pressure "'baromin'      : '%.4f'," "" "pressure_inhg(x)"#
#calc "temp_f(dew_point(data['temp_out'], data['hum_out']))" "'dewptf' : '%.1f',"#
#calc "rain_inch(rain_hour(data))" "'rainin' : '%g',"#
#calc "rain_inch(rain_day(data))" "'dailyrainin' : '%g',"#
}

3) Add an entry to the 'weather.ini' file:

[live]
services = [...', 'pwsweather', ...']
...

Let us know if it works out for you too :)
