My bmv-712 was working fine for a month or two, but now it's not showing any current draw when I have things turned on that would previously show up as loads (lights, fan, etc.). Very weird (the lights and fans run, so current is flowing, but zero is shown on the app). Anyone have an idea?
TIA
Possibly a bad connection between the 712 and shunt
Power cycle the BMV.
Disconnect all loads/charger/other from system side of the shunt.
Enter Battery Settings > Zero current calibration (CALIBRATE) - make sure you read the prompt before executing.
Restore system to original config.
Hope.
Well it's an even bigger mystery now that it's working again. I did the zero calibration, but it was ready working before that. No idea why it stopped or started working again. I will update this thread if I ever figure out the root cause.
