BEWARE!! I had previously set this new app up to work along with Sunny Portal. Both were working fine some time ago - although, I must admit the old Sunny Portal app displayed more data than this new one and I always preferred and used the old one up until now. I signed into Sunny Portal today, first time in a while, to view my solar station’s stats and it said I had to use this one. So, I opened up SMAEnergy and there was no data anymore. I was instructed to either create an account or transfer data. I tried to transfer, but it would not work. It did not except my credentials. Also data transfer does not appear to work for the PV system that I have; 2 Sunnyboy inverters with each having a Webconnect module (No batteries or Web box). When I entered the name of my system to be imported, it said it was not possible,So it would appear that all my historical data is gone! All I can say is it worked a while ago and now it does not. What am I supposed to do? Just a short update, as I did go into Sunny Portal on my Mac and I was able to see the current data as well as all historical data. So it appears that it is an iOS app issue. This new app needs to be able to import ALL existing Sunny Portal accounts!
