I reviewed the app last year and gave it 1 star because it wouldn't work at all. This year I got it to work but ONLY by setting it up via my computer, not the app. It has worked OK for 2 months but now has stopped. Says 'offline' and 'no data available.' Everything else works, which leads me to believe that it's not a phone or wifi problem, it's a Fronius problem. Their wifi systems just aren't sufficiently robust. EDIT, found wifi access point had stopped (why?) Restarted but still not working.

Lots of negative reviews here. For me this app has been fine. It works no problems. Does not log me out often. Has the basic information I need for monitoring. It could certainly be developed and refined much more. The "Energy" tab and historical data is very basic and hard to navigate. I have just decommissioned a recent SMA system for a Fronius install and their app is slightly better overall.

Getting really annoying how frequently I have to login in recent months, now have to login at least once a day. used to be weeks between logins. For the battery control, needs a "charge for n hours" dropdown rather than just charge until full. Also need a "start discharging at hh:mm" so you can charge in the evening but then starts the discharge while you sleep, knowing it will have enough power to reach the morning.
