See the Victron Energy documentation how to get [root access](https://www.victronenergy.com/live/ccgx:root_access#root_access).


## Which version do I have installed?

You check check the installed version in the [driver log files](../troubleshoot/#driver-log-files) or in the remote console/GUI under SerialBattery -> Device -> Firmware version

## How to aggregate multiple batteries?

You need an additional driver for that. Here are a few listed:

## Why is the battery current inverted?
Some Daly BMS send the current as inverted value. This can be corrected by setting `INVERT_CURRENT_MEASUREMENT` to `-1` in the `utils.py` or `config.ini`. See [How to edit `utils.py` or `config.ini`](../general/install#how-to-edit-utilspy-or-configini).

Expand All @@ -223,6 +227,10 @@ Most unstable communications arise due to:
* Cheap USB Hubs: Make sure you are using a qualitative USB Hub with enough power.
* Raspberry Pi: Do not use a charger for powering the Raspberry Pi. Instead buy a power supply with enough power.

## Why is my `utils.py` always reset to default values?

Probably you forgot to remove the USB/SD card with the `venus-data.tar.gz` after successful installation. Please delete the file or remove the USB/SD card. This is fixed with `>= v1.0.20230512`.


## Fix white screen after install
Normally this will happen, if you were on an older firmware for your GX.

### Remove GUI changes

Execute the command (matching your driver version) below to restore the GUI.

If you don't know which version of the driver you have installed then try first the option for `>= v1.0.0`. If you get the error `bash: /data/etc/dbus-serialbattery/restore-gui.sh: No such file or directory` try the option for `<= v0.14.3`.

#### Driver version `<= v0.14.3`
```bash
# restore original qml
cp -f /opt/victronenergy/gui/qml/PageBattery.qml.backup /opt/victronenergy/gui/qml/PageBattery.qml
reboot
# restart gui
svc -d /service/gui && sleep 1 && svc -u /service/gui
```

#### Driver version `>= v1.0.0`
```bash
bash /data/etc/dbus-serialbattery/restore-gui.sh
```

### Update to the latest firmware
If the removal of the GUI changes did not help, you can force a reinstall/update of the firmware. This takes about 5-15 minutes depending on your device and internet connection.

```bash
/opt/victronenergy/swupdate-scripts/check-updates.sh -update -force
```

If this also did not help then execute this command to prevent any driver to auto install after firmware update.

```bash
mv /data/rc.local /data/rc.local.backup
mv /data/rcS.local /data/rcS.local.backup
```

Now run again the reinstall/update of the firmware.

## How many USB to serial adapters can I connect?
It seems that the Victron GX device has a limit of maximum 8 USB to serial adapters. See [Serial battery driver not found if other VE.direct-USB devices are present](https://github.com/Louisvdw/dbus-serialbattery/issues/422)

# dbus-serialbattery

This is a driver for Venus OS devices (any GX device sold by Victron or a Raspberry Pi running the Venus OS image).

The driver will communicate with a Battery Management System (BMS) that support serial communication (RS232, RS485 or TTL UART) and publish this data to the Venus OS system. The main purpose is to act as a Battery Monitor in your GX and supply State of Charge (SoC) and other values to the inverter.
The driver will communicate with a Battery Management System (BMS) that support serial (RS232, RS485 or TTL UART) and Bluetooth communication (see [BMS feature comparison](../general/features#bms-feature-comparison) for details). The data is then published to the Venus OS system (dbus). The main purpose is to act as a Battery Monitor in your GX and supply State of Charge (SoC) and other values to the inverter/charger.
