Hi Gary,
Thanks for your message, much appreciated. Based on the data that I'm
getting from the GW2000/WS90 with debug enabled, I've set up the following
in weewx.conf. Hoping that on my next rain event I'll get some data. I've
not added any other fields to the database; although it would have been
nice to have the rain history from the last few days when I set it up. We
had some good downpours from the recent Potential Tropical Cyclone #1 as it
passed.
[GW1000]
#p_rain p_stormRain p_rainRate p_dayRain p_weekRain p_monthRain
p_yearRain
[[field_map_extensions]]
rain = p_rain
stormRain = p_stormRain
dayRain = p_dayRain
weekRain = p_weekRain
monthRain = p_monthRain
yearRain = p_yearRain
rainRate = p_rainRate
Hopefully this thread will be useful for someone with a new GW2000/WS90
Thanks,
Arthur
