I have qty 4 12v 314 Smart Mini in Parallel.  One 12v battery will connect to the app, but all data fields show 0.  See attached photos.  Other 3 batteries show complete data.  I assume the battery is working correctly, but have no way of verifying.  Maybe a firmware update will fix it? I need to set the battery for parallel mode.
The screen that shows the individual cell voltages seems to show the correct voltage.
