I had left a comment on another thread ( https://www.cloudyni.../#entry11303301 ), but got no takers so I decided to jump in and do this myself.
This post is just an FYI in case anyone is interested in my efforts:
It's been quite a few years since slinging code using MS Visual Studio, but was able to install VS 2019, the ASCOM dev platform for C# and get my $110 AcuRite PWS data into SGP .
My research into this showed that Weather Underground (wunderground.com) now uses "The WeatherChannel"s IBM cloud to host the data set from AcuRite PWSs. The older MS VS (VB & XML based web call methods) changed when Wunderground transitioned to weather.com. So that ASCOM Wunderground driver (WUAPI-ObsCon) doesn't work (EOL), but has some helpful routines in VB.
It turns out the OpenWeatherMap.org ASCOM driver uses C# and JSON based calls, which are similar to what weather.com uses, so I decided to use that as a basis for getting my PWS data into SGP (and my FITS headers). OpenWeatherMap is a nice site for curated weather station data calls (v2.5) with AI to interpolate weather conditions near your GPS location. But it won't read PWS stations with the default ASCOM driver.
But all was not lost for doing PWS links. They also have a newer set of (v3.0) methods that are completely different, but accept PWS data using the same ApiKey for v2.5. Anyway, in playing around with all this I decided to take the best of what was in both of these two ASCOM drivers and add a third option to link to OpenWeatherMap v3.0 PWSs. I will post results as they come in.
