@Victron_fan_8185

Don't know the batteries you are referring to.

If it is correct on the console as in all modules online.

You will see one battery bank on VRM not individuals and the few details that the battery sends to the VRM.

Will move this to mods forum, might be better to pose the question on the thread by the original author. It is completely unsupported.

There is a link to git as well.

Not need to move it. That's not an issue with serialbattery. In general to see more than one battery on VRM, do the following at the remote console

- Settings/System Setup/Battery Measurement: set the batteries you want to see to "Visible". You may also set a Name to be displayed.

This way you will see the values of batteries. VRM will d

Unfortunately Victron only allows one battery Battery Monitor to be set at Settings/System Setup/Battery Monitor. But this is no problem at all if you have only batteries handeld by serialbattery.

To handle multiple batterys connected with serialbattery I recommend aggregatebatteries: https://github.com/Dr-Gigavolt/dbus-aggregate-batteries
This will aggregate the batteries on a new virtual battery called "AggregateBatteries". Similar to that what Pylontech does with multiple batteries. After aggregatebatteries works well, set Settings/System Setup/Battery Monitor to "AggregateBatteries".

Done! Works very well.

I don't like aggregatebatteries, i want to see them separately as i already do with the first 3...

With aggregatebatteries its just another virtual battery. The others do not vanish. Try it.

Therefore I installed the Victron Shunt, this i my main battery measurement device.

The several packs have their own SOC. That's what I want to see in VRM. It works fine for 3 batteries, why not for 4 or more ?

The real advantage of aggregatebatteries ist that it is able to aggregate all information of the BMS and give these to the VenusOS. Like min/max cell voltages, min/max temperatures, ....

It also calculates the CCL and DCL dynamically from all connected BMS.

As the smartshunt is not able to get this information and VenusOS only support only one battery monitor to be selected, aggregatebatteries has advantages compared to just use a smartshunt.

I add some Screenshots to explain what I mean, it is not a problem of dbus-serialbattery - All 4 batteries are shown in Cerbos device list:

1698867020630.png

And also the shunt
and here BATT. 4 is missing what is the root cause for not displaying in VRM
1698867098692.png

in VRM device list also 4 Batteries are shown:

1698867245479.pngbut in the VRM Dashboard not:

1698867288457.pngI can display the Multiplus there but not the 4th battery

I hope, this explaines my problem.
It is not a problem of dbus-serialbattery, all 4 Batteries uses the same Hardware and the same code. in devicelist all four are shown with all details, also seen with dbus-spy.

the problem starts by the second picture, were batt.4 is missing, so it cannot enabled for HTML5 and VRM..

What will you see on Settings/System Setup/Battery Measurement?

Is there Batt4 avalable to select to be visible? Please show the screen.

With the new VenusO I do also see only one of my two battery banks to select.:

1698873866921.png

There should be another SerialBattery (jbd) but is has vanished.

Fortunately I have already selected the second battery bank to be visible. Thus It is shown.

Looks like an problem with VenusOS v3.12 that one of the banks can not be selected. I have setup my system to automatically install always the latest version:

Maybe I should change that.

I am Using v3.11 on my CerboGX:

1698901070971.png

I also have JK BMS over RS485 an to USB-Converter connected to the CarboGX. All batteries are shown in device list, but the 4th is excluded from battterie management and therefore it cannot be set visible.

I have posted it above (in german: Batteriemessungen) I tried to scroll up and down, but no more entries appear, you see all in the above screenshot. I paste it here again:
1698907474728.png

You see I have scrolled down, and no more entries appears.
but in DVCC / BMS:

1698907568949.png
Batt 4 appears.

I don't want to forget to mention that in VRM Dashboard extensions all 4 batteries appear an I am able to add charts of SOC or Voltage and current, and they are filled with data:

1698909034759.png

so the Cerbo sends all Info to victron but on the dashboard batt 4 is missing, but the root cause is, that i cannot enable them due to that they not appear in the appropiate menu.

Thanks. Looks like an error with VenusOS 3.11 and 3.12. Hopefully someone from Victron reads this thread.

@herzigwi It seems so, today I looked at my CerboGX (v3.11) menu:

1699332491760.png

and battery 4 appeared (the multiplus has no name here!) and I set it visible:

1699332633271.pngthe 4. battery is visible !! It is idle because I disabled discharge, it should be charged for the first time.

I hope the next (5th) battery will appear in the bottom right or left corner (multiplus moves to right) above.

Thanks for the information. I have just looked at my VenusOS-Console: My also previously vanished battery (on battery measuments) does now also appear. Without any updates and changes from me.

Very strange:

(a) Is Victron able to change this remotely or

(b) does "time heal all wounds"?

;-)


(b) would be nice, but (a) is something I do not understand..........

I believe in (a):
