Hi and thanks for reading this.
I have a REC-BMS (Victron version) connected to a Raspberry PI3 with CAN-HAT running 2.60 which has worked very fine for some weeks. Tonight I connected a Multiplus 12/1600/70 via MK3-USB cable to the PI. I also have a BMV-712 connected via a VE.DIRECT cable using the same shunt as the REC-BMS.
All devices appear on VRM Remote Console and look fine. The battery charged to 14.2V just fine and current quickly tailed away to zero-Amps. After a short period of use, an Automatic Monitoring 'DVCC Firmware insufficient alarm: Warning' appeared.
My Multiplus is an 1906 model running firmware 209; could this too old for REC-BMS control? I see a Victron helpful stating 19xx model is supported. Also have two-signal lithium assistant running if that makes any difference.
Some VRM screenshots attached somewhere below.
