edit: I believe this has been fixed Overall, amazing app. But I have a problem with my River 2 Max. For some reason, sometimes it will stop allowing itself to be charged via wall power. I use it as an uninterruptible power supply (UPS), and sometimes it will just lose the ability to charge. Then all of my stuff will be unsaved, and I have to wait until it goes to 0% to be able to charge again.

Generally app is quite useful, despite minor issues. The biggest is input/output charts are, on average, 50 percent empty. 12:01 AM, Sun. AM, or 1st of month, they are almost completely blank. My utility deals with this via "Previous Cycle" control that overlays older info in a different colour. Even better, show the last 24 or 48 hours, the last 7, 10, or 14 days, last 5 or so weeks, and the last 12-18 months. Sunlight and weather don't vary with the calendar. The format is arbitrary.

Day 1: The app worked great last night. But in the morning it didn't work. I've been trying to set it up since then. Very frustrating (1 Star). Day 2: Continuing to restart the app (1 Star). Day 3: After several attempts, I was able to reset my Delta 3 Max Plus (progress). I'll turn in for the night and see if it works in the morning (2 Stars).
