Thanks for the info! I actually just received an email from Bloomsky regarding my question, see below:
Thank you for contacting BloomSky and thanks for your interest in the new products! There aren’t many, but, the main differences between the Sky 1 & 2 is the set up process. The set up will be streamlined with the Sky 2. I would take advantage of the current sale and purchase the Sky 1+ Solar panel. This is probably the lowest it will be. Luckily, the Storm will work with either version of the Sky devices. So there should be no problems for our new or loyal users to set up a new Storm device and start receiving new measurements. The new devices are slated to be released before the end of the year, hopefully September or October.
So it sounds like you made the right decision, and I'm about to as well. Hopefully my setup is as easy as yours!
