@Louis van der Walt, @Jeroen, @mvader (Victron Energy)
Thanks very much for your help (in getting various python modules loaded) and the code developed by Louis, I've now got the SPI connected BMS running and under test:
Currently running v2.71
Please can any one tell me the dbus address for the boxes circled in red (1-3)?
Also what variable type replaces the "unknown" on the Alarms page?
Once I get the code tidied up I'll make it available through Github. The BMS is 8 channels, and has relays for load and charge disconnect, and also for Gen Run (2 wire).
