I have a SmartShunt 500A/50mv and the current reading using VE Direct is 1.0A higher than when using bluetooth (if I don't recalibrate the zero point). If I connect just the battery and no load, reset the zero point using bluetooth and VictronConnect I get a reading of 0.00A. If I then plug in a serial connection to the VE Direct port and watch the serial stream of data on a terminal app or with VictronConnect it reads 1.0A. If I then do a zero reset using the VE direct port the reading changes to 0.00A. If I then go back to using bluetooth the reading is 1.00A. If I apply an actual current through the shunt there is a 1.00A offset unless I reset the zero point again using the same connection method as the reading are taken with. I'm using the latest firmware. Any ideas what is going on and how to fix this?
