i downloaded from Weatherlink 2.0 all the data I sent them. they have you select the time frame, then send you a link to download it in Cvs format. I noticed it was in 1 minute intervals,
I am of the opinion they are moving to only cloud support and eventually the loggers -serial, usb will be less commonly available, with the push to the IP. Considering they can charge you not only for the logger that is 100 dollars more than the serial or usb logger and then charge you for the service to display your data is pretty good marketing. Kind of like you go out to eat, pay for the food, but you have to pay more to actually eat the food.
I don't know if this business strategy is all that great or if it helps other businesses develop their product in such a manner that it helps us out. If I knew that back in 1993, perhaps I might have opted for a different hardware, I don't know. What I do know is that the 3rd party software able to fill that gap.
I like Weatherdisplay because it has the ability to be used by different hardware companies. you are not tied to just Davis .
I have a mac so I am limited. I use Weathercat because I can export the data . I take the data , use Excel to put it into a spread sheet. I calculate the average, max and min, count and other things and save it and have multiple graphs showing change. I also have other charts that I put in the data . For me it helps, then I save it. I have data way back. I just don't put it up onthe net anymore. No one cares about it but me.
Good luck
