Not too bad

Not much control over the battery in app, so you have to login to the device via webpage to do the good stuff. Would be awesome if they added widget support so at a glance I can see what everything is doing without going to the app.

Thanks for the update!

High praise for the Sonnen developer team implementing feedback so quickly! I previously submitted a lower review with my comments. Overall, wonderful app.

Like the update but prefer the old Live View

I actually like the interface for the most part and don’t mind the changes but the new live view isn’t my favorite. At a glance I could see the energy numbers, power flow, percentages, and more. This one it seems like I have to look around, scroll around, and that it’s designed more to look fancy than to give information. The graphic doesn’t give any numbers anymore.

Would also love if you made it native to the iPad (and macOS) so I could use it there. It’s be amazing on a bigger screen. A way to integrate other circuits into it with sensors so I could monitor energy usage not on the battery would be great too.
