Is there any loss of functionality in Victron Connect or VRM if I connect the battery BMS with a Victron ‘rs485 to USB dongle’ instead of the usual bms ‘can cable’?
And will it work directly without any further issues?
If it will work I want to connect 2 batteries each with the rs 485 dongle, to get individual battery monitoring in VRM.
@Frisianstar the batteries that can be “seen” by the BMS Can cable are specifically noted by Victron as being able to be monitored. If the batteries can be seen by the BMS CAN port (which I now think is simply another VECAN Port on newer CerboGX devices) I don’t think the RS485 interface to the USB port on the CerboGX will work. I am not suggesting it could be arranged using NodeRed but I dont think it would simply “Plug and Play”.
i had 2 batteries connected vie RS485 - with dbus-serialbattery - Daly BMS
a new release gave many connection errors
I switched to CAN now - no more errors
Thanks for the reply.
I have now one of the two batteries connected via a original Victron Can bms cable type A, works good.
Combining the identical second battery to the first one doesn’t work (jk bms v19.5) unfortunately there isn’t a solution for this problem, no working update or so.
Connecting each battery with rs 485 to the Cerbo gx has been done successfully by one guy on this forum some time ago.
I have a Multiplus II 3000/48 GX with 2 x JK BMS batteries connected with a USB HUB and 2 isolated USB RS485 devices.
Software: dbus-serialbattery
I will not use the CAN port on the Mltiplus II GX because the CAN port is not isolated.
