Log-in bug, after entering credentials app crashes. Upon reopening then works ok. Updates to this app and web portal are no where near real-time (only 2-3 times/day) so, not really useful for any kind of real-time or even recent data. Not much point in having an app that tells me about yesterday.
Feb 11 update: app no longer works at all, will not login to server. Deleted app and reinstalled, no help.
Feb 12 update: after multiple reinstalls app back to where it was, working but updates often many hours late (this is a portal/server issue as app mirrors web portal report and web portal just as far behind). I have confirmed w/SMA tech support that my system is reporting to server every 15 min yet server updates only every several hours.
Feb 14 update: no portal update at all. As-of 6pm showing only yesterdays data.
Overall, a very poor showing from a technology driven company. I note that app support is all in German, so clearly this company could care less about English speaking clients who have paid for their products (app might be free but inverters and web box werent!). Doubtful they even read these reviews.
