App dead

Can’t accept the terms, app won’t open.

Terrible

I recently installed a Fronius Wattpilot EV charger and the two apps don’t communicate with each other properly. At times Solar.web shows power flowing FROM my house yet I don’t have a battery, so that’s impossible. The household consumption data doesn’t get accounted for in real time so my EV will charge with power from the grid even though I have the Wattpilot set to only use surplus PV. Fronius should have ONE app only for all linked devices and then it may be better at providing useful graphics about what’s happening with your solar system. Tech support is terrible from Fronius Australia. Do better.

Could be much better

The app is stable and basic information is good. Appreciate the dark mode which is not available as yet on the Wattpilot app. But could be so much better. Please consider putting more battery controls inside the app for your reserva product rather than the web interface. Things such as I want the battery to charge from grid from x to x until full, or discharge this amount into grid between x and x. Also allow the user to specify how fast to charge when from grid when emergency charge button pressed rather than limiting it to 1.5kw.

Repeated login

You are forced to re-login everyday, often multiple times a time. Useless app if it cannot be readily and easily accessed.

Vast improvement

The new version 4 of the app is a vast improvement over earlier versions. In particular, Wattpilot vehicle charger information is graphically represented on the Home Screen.

What will take the app to 5 Stars is Fronius consolidating the separate Solar.web and Wattpilot apps into a single app.
