Hi,
Just sharing a bug that's been a pain, and the simple fix i finally found, for anyone who may have the same issue!
On my victron smartsolar mppts and bmv712, the stored trends would NOT upload to the app.
Every time i would open the trends page, i would only see the current data appear, starting at the second i opened the device. Every time i closed or disconnected the device, it would clear everything. No access to stored data!
If you have that too, the fix is simple!
Just click on the three horizontal lines button on the bottom (between the zoom and play functions), then "clear all data"
I never thought of that since data was already clearing itself... but now it records and uploads without problem to the trends page for all my devices!
Hope that helps
