Hello! I had been struggling to get it working but I just pulled the Nightlies from Dev / Mr-Manualel and everything worked beautifully right after I did the install. However, when I reboot the RPI - everything disappears.

So this is from all installed on 3.15 of VenusOS and I installed the nightly for dbus-serialbattery and now having issues on reboot

• the driver is not getting re-installed. Come to find out there's an error in /data/rc.local as the command to start the driver is placed after "exit 0" so it never runs on startup. Please take a look at the rc.local how it's being created:

The following is my file for rc.local to get it running
(I moved the exit 0 to bottom - however when the reinstall-local.sh runs, it's put it again before)

root@raspberrypi2:~# tail /data/rc.local

/data/tft35_scripts/fbcp /dev/fb2 &
/data/tft35_scripts/backlightCtrl /dev/input/touchscreen0 45 &

sleep 5
#bash /data/etc/dbus-serialbattery/reinstall-local.sh
#/data/etc/dbus-serialbattery/reinstall-local.sh
bash /data/etc/dbus-serialbattery/reinstall-local.sh

exit 0

example:
root@raspberrypi2:~# bash /data/etc/dbus-serialbattery/reinstall-local.sh

No CAN port configuration found in "/data/etc/dbus-serialbattery/config.ini".
You can ignore this, if you are using only a serial connection.

Install notes

#################

SERIAL battery connection: The installation is complete. You don't have to do anything more.

BLUETOOTH battery connection: There are a few more steps to complete installation.

1. Add your Bluetooth BMS to the config file "/data/etc/dbus-serialbattery/config.ini".
   Check the default config file "/data/etc/dbus-serialbattery/config.default.ini" for more informations.
   If your Bluetooth BMS are nearby you can show the MAC address with "bluetoothctl devices".

2. Make sure to disable Bluetooth in "Settings -> Bluetooth" in the remote console/GUI to prevent reconnects every minute.

3. Re-run "/data/etc/dbus-serialbattery/reinstall-local.sh", if the Bluetooth BMS were not added to the "config.ini" before.

ATTENTION!
If you changed the default connection PIN of your BMS, then you have to pair the BMS first using OS tools like the "bluetoothctl".
See https://wiki.debian.org/BluetoothUser#Using_bluetoothctl for more details.

CAN battery connection: There are a few more steps to complete installation.

1. Add your CAN port to the config file "/data/etc/dbus-serialbattery/config.ini".
   Check the default config file "/data/etc/dbus-serialbattery/config.default.ini" for more informations.

2. Make sure to select a profile with 250 kbit/s in "Settings -> Services -> VE.Can port -> CAN-bus profile" in the remote console/GUI.

3. Re-run "/data/etc/dbus-serialbattery/reinstall-local.sh", if the CAN port was not added to the "config.ini" before.

CUSTOM SETTINGS: If you want to add custom settings, then check the settings you want to change in "/data/etc/dbus-serialbattery/config.default.ini"
and add them to "/data/etc/dbus-serialbattery/config.ini" to persist future driver updates.

After I reboot, I guess it takes ~5 minutes for the services to come up for blebattery and inbetween it might be generating errors about BMS not being available...
