Using WUnderground.com to integrate Personal Weather Stations

Hi,
I’ve just ordered a gen 2 and was mulling how to incorporate my Davis weatherstation’s data. It reports to Wunderground and also to Citizen Weather (cwop.aprs.net) but this latter sometimes causes trouble - randomly causing the Weatherlink software to hang so I’ve taken to switching that feed off. Does the Rachio access CWOP (also= HamWeather) as well as PWS? I have a PWS account which hasn’t been used since I junked my Oregon Scientific weather station 7 years ago but I guess I could use the script to feed it. Trouble is I’m already accessing the Wunderground API to feed my VERA Z-Wave controller with a PLEG add-on and fear I may get into trouble with WU’s access limit if I run both. Maybe there could be a way for the Rachio to access the VERA weather data employing some sort of ITTT? Is there a step by step idiot’s guide on how to set up the script (looking at that code makes me feel queasy, I’m no good at that!)?
