Pack 1 (master) of 7 errors when I get details.

[CrappyTan]

I have 7 2000C with firmware 1.7 flashed onto them. They all functioning as-expected and talk quite happily to BatteryView and the Victron Inverter.

When I try get details for pack 1 (the master) the python crashes on the line

    assert got_frame_checksum == int(frame_chksum, 16)

If I run pack 2-7, works just fine.
How can I debug this?

I have this problem but only when I run with a plain 2000 as the master and 2000C as secondary.
