Yes, the software-only solutions I referred to are the WeatherSnoop, for Macs, or the software linked above for PCs: http://kevin-key.blogspot.ca/ I have both Macs and PCs, including some that are on 24/7, but those systems all have other functions and I don't want to tie them up running weather software, or be dependent on them to stay on. (I can restart anytime I want when home for movie streaming purposes, for instance, but if it was to crash while I was on vacation, I'd lose all weather connectivity until I got back home, which defeats the purpose!)
I have an Ambient Weather WS-1200-IP Observer. It includes the Observer-IP module automatically collects the station's data to upload, but which, unfortunately, will only report that data to Weather Underground (which all works brilliantly, except the Iro can't see that data). I could buy the $209 WeatherBridge from Ambient, or essentially building my own, per the instructions on the Meteobridge website (and buying the software license), for around $100, and that would allow uploading the data to any number of weather reporting/recording services, including the ones that are directly supported by Rachio (like CWOP and PWSW). But I'm not eager to spend yet another $100-209 just so I can use the actual weather data that's already being recorded above my roof.
