BMV-712 Main Voltage Showing 0.02V

I have a BMV-712 connect to 2xVictron Super Cycle batteries, today my monitor started reporting an incorrect battery voltage of 0.02 or 0.03V. This is on both the device itself and the android app (via bluetooth), nothing has changed in my system except for taking a firmware update on the app.

I've checked the voltage with a meter and its reading 13.08 from the shunt to my fuse where the power supply for the BMV is located. I also unscrewed the inline fuse and looks to be intact, just to be sure i checked the voltage from the end of the fuse to the shunt and again was 13.08V so seems to definitely be a software / device issue? I've done a number of factory resets without any joy always just displays the .02V after the reset.

Kind of out of ideas here and would welcome suggestions.

I’m having the same issue. The battery monitor two days ago reported a low voltage warning and is showing 10.5 to 11.36 v which is under the actual voltage of 14.1 v on my gel 12v house battery. Are there any solutions out there?

I am having the same issue except on new install. Reading is also staying between .02 and .03. Wondering if you found a solution?
