Good stuff but now bad with latest update

Latest update v2.03 messed up a few things !

1. For a few days the refresh wasn’t working seems this was a back end thing and now working. No longer an issue.

2. you got rid of the AI support.

3. The grid connection now shows generator connection. (I don’t have a generator)

**Original review before July 21 below. **

Overall I appreciate the app and looks
Nice.

The easy switch between simple and detailed allow me to see my batteries down the line and if they are balanced. As another person indicated, this prevents changing things in the Home Screen on accident, the style is nice and closer to HA.

I am not looking for more functionality just a different way to view the information. The graphs could use some work, but a great step forward.

I still use both apps, and appreciate I can compare if the readings are accurate(delayed).

I am using this app more and more.

Thank you and keep building on it!

Two Stars for Dark Mode

App Does not refresh often or on command, likely heavily throttled. Had to use the other app to get this one working. It does the trick but could be improved with quicker updates, visually is great.

Pretty but no real function.

This app looks exciting and flashy. But no utility is to be gained. The graphs have no data lines with numbers. They are just line charts the go up and down. There still is no way to annotate ac coupled power as a secondary PV input. In fact it doesn’t display data for ac coupled power at all. The “advanced” settings adjustment is barely basic. You are missing so many important aspects of setting parameters for battery and power usage. This app is a failure if you really wanted to do anything with your system other than look at it, and even then you won’t get half the data the old app gives. Very disappointing.

Almost there!

Much beter with automatic parallel selection, and cleaner interface. Hope one day features like solar yield today tomorrow are also in the app. And more push notifications options. All in all good

Big improvement

Much better than the previous app.
