BatteryAggregator by pulquero shows 0% SOC even if the batteries are between 20-30% SOC #884

Closed Martinmaker92 closed 10 months ago

Martinmaker92 commented 10 months ago

Describe the bug

I have installed the BatteryAggregator by pulquero via Setuphelper and it works fine. There is only a problem that the Aggregator sometimes shows 0% SOC but just for a short time. (10-30seconds)

i am using V2.4 of the aggregator 18S system with JK BMS

dsfad battery aggregator

How to reproduce

it happens randomly over the day

Expected behavior

it should not go to 0% soc

Driver version

1.0.20230531

Venus OS device type

Cerbo GX

Venus OS version

3.11

BMS type

JKBMS / Heltec BMS

Cell count

18

Connection type

Serial USB adapter to RS485

Is only the aggregator showing 0% or also this driver?

Martinmaker92 commented 10 months ago

What do you mean the driver?

in the remote console?

this is interresting about 9:00 it showed 0% the lower one is the aggregator.

What do you mean the driver?

dbus-serialbattery

You have to open an issue in the repository of the aggregator and not dbus-serialbattery. We cannot do anything here.
