When it works it's fine. But at start it often fails to fetch realtime data, then it just shows zero watt produced and won't refresh. Besides, the backend for the app is down way too often. And when it's down, the app hides the real error, loses its login details, and forces you to logon again. Only to be met with another timeout.

Although my PV-system is connected to the internet, the app (and the website) keep telling me that it is offline, that there is no data available. Sometimes it works for a couple of minutes. What's the point of having an expensive solar power system when we don't know how much it's generating and how much we are using? Extremely disappointed!

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.
