Just getting the mode of upgrading my hub. Got the same email other s have received. Just to echo the sentiments of others, it would have been nice if the would have include a link for upgrade instructions in the same email where the sold you the new system. I understand there is a replace function available, and you can save the last 31 days of history in a .csv file. Is there anyway to reload the .csv file so it looks like it use to before the upgrade ? Or are you limited to just reading your old data from the .csv file ? Thanks.
