My set-up:
- Multiplus 2 with external Cerbo-GX
- Large OS with Node-red
- Lan connected
Some weeks ago i found out, that I got no longer values values via: Node-Red-System: Venus System-Battery voltage(V)
When I checked Remote Console: No values for battery.
After a bit of search wihtin Node-red, I found a different node, providing the battery voltage.
Thus I switched to: VE.Bus System: MultiPlus-II 48/3000/35-23-Battery voltage (V) and it continue working.
Today I rebooted Cerbo-GX and get no values on remote console:
However, when i go via vrm:
I see the data, still nothing on Battery.
Any explanations / help available ?
You may have to choose a new battery monitor in settings > system setup.
thanks for the hint.
You’re right the entry is missing, I’m using an JK-BMS which seems no longer connected.
That’s a bit of work, as it’s all outside in a kind of “coffin” 
I’ll check it out tomorrow.
Okay, today, nice weather, cold, but sunny - ready to open the “coffin”. One final check, first and …:
Strange - today I see my JK-BMS:
However with “zero’s”.
If I go deeper, into cell voltages:
It looks all good !
However, still: No Battery data
If i change in >System Setup< Battery monitor from "SerialBattery(jkbms:Ble) to Multiplus-II 48/3000/35-32 on VE.Bus, I get the data:
A bit weird !
