Ratings and reviews

Works, but it's usefulnes is very limited even with the paid subscription. There are simply not many options for any kind of meaningful automation, even on the inverter's local webserver. For quickly checking the system it's fine though. Not a fan of the new flow animation, but can be changed back in settings thankfully. For anyone wanting more, I recommend setting up a proper Home Automation system like Home Assistant and/or NodeRed with SolarNet and Modbus integration. That works very well.

Since the latest update, the app has become largely unusable. Live data is rarely available because the connection frequently fails and displays error messages instead. It's impressive how an update managed to break the core functionality of a monitoring app. Well done....

"Reduce motion" is very welcomed but the arrows would be better placed on the lines between the circles, rather than next to the text. 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.
