Thanks for asking. It would/could be either. Problem is I can't tell which but I am leaning toward WLPC because of history. Both show updates are current to the time. As far as history I got tired of rebooting my computer to restore communications for upload (USB). This was 2010 or so. I finally gave up and took the configuration down*. The VP2 worked fine for my wife to know how to dress for the day where she lived and worked on site at a fed hatchery. I was 75% of the time away building our home for he future. When she retired I brought the system here and set it up and a new site location. But we didn't upload. By then the station was in need of a massive refurb. When it came back from Davis I added the UV/Solar. At that time, 2019, I installed WL and began uploading data to the new site.
In my opinion, Weatherlink (at the PC level) hasn't improved much. Dial up modem config still there? Weatherlink in the cloud does great, to the degree it receives the upload. Yes, yes, don't launch on me... there are a lot of machine / device things. But it is a far cry of the 2010 days. And here is my source of doubt.
Davis can pull $50/year for the cloud stuff but they could maybe update things? Maybe make things a bit more reliable and current?
* When I took the weather station down, around 2010, I got a call from a guy in Pendleton asking why? I told him I couldn't have my PC being rebooted constantly (worked from home). He offered to come to our place and install Cumulous because WL was so flakey. A known issue and they aren't investing any recourses to fix it and he wanted us back on line.
