VRM not displaying BMS Cell Data

Hi All

I have 3 Victron Lithium batteries, BMS, Cerbo, BMV712 - all connected and working perfectly.

Set up VRM and every, again, working perfectly, I am getting all the data coming through.

However, there are 2 widgets, showing no data - they relate the BMS.

See attached picture - any thoughts what the BMS is not sharing this with VRM ?

Thanks

Tim

What BMS do you have? No Victron BMS provide that data.

Hi Matthias

It is the Victron VE Bus BMS - https://www.victronenergy.com/battery-management-systems/ve-bus-bms.

Do you know if the BMS should show in the Device List on the VRM ?

Thanks

Tim

I think it's BMS dependent. The VRM portal facility is there but if your BMS doesn't publish it then it will stay empty. Here is Freedomwon that does publish the data - no idea why it's intermittent on the one but still, it's there.
