Is there any way to see a historical (ie hourly/daily) power consumption on the battery monitor? I'm a bit disappointed so far that I see only a "deepest discharge", which doesn't help me understand what by power usage was the evening before.
I woke up this morning at 4am with my 48V lithium batteries dead and I have no idea why. A graph of hourly power usage would have been able to explain things. The Trends tab unfortunately only shows info based on when I most recently opened the app (ie usually no more than a few minutes prior), rather than for the hours before.
Is there a way to interface with raw data on the device so I can write my own software to monitor things? I have a raspberry pi with bluetooth and would love being able to collect data from the monitor, which I can then customize.
For example, it would be helpful for me to get notified that the power is getting low (and could be dead before morning), so I can unplug items before I go to sleep. It would be helpful to customize this notification, ie based upon if there's a genuine risk to the batteries being dead.
People have suggested getting the battery disconnect but I honestly need to have fair warning before it's too late. So I know to unplug my computer, TV, etc (less essential items) so my fridge can keep running.
If there was some programmable interface I can gather data, that would be really useful and I'd consider keeping the device. Otherwise, I'm just going to return it and look elsewhere, because it's definitely not worth the $200 when there's no historical logging (unlike their charge controllers).
Also, now the battery monitor says "100%" even though it's nowhere near that, so it's a bit useless at this point. I had to shut off my batteries so the monitor turned on via my panels, which might explain the issue.
