Any other information that may be helpful

I modified the current settings, after generating the log. (thats why it says: @400000006492e89f1b54c1ec INFO:SerialBattery:> MAX BATTERY CHARGE CURRENT: 200.0A | MAX BATTERY DISCHARGE CURRENT: 200.0A @400000006492e89f1b772e6c INFO:SerialBattery:> MAX BATTERY CHARGE CURRENT: 150.0A | MAX BATTERY DISCHARGE CURRENT: 150.0A (read from BMS))

Please install the latest nightly version of the dev branch.

Thanks for your response. Just did it, now i`m at v1.0.20230620dev. After the first reboot, only one battery connected. The second one did this in a loop:

After another reboot, the second battery started also. I will watch, if the initial problem occurs again.

mr-manuel commented 1 year ago

You installed with the install script or by uploading via FTP? This looks like a line endling problem.

itsdaveit commented 1 year ago

I Installed with:

wget -O /tmp/install.sh https://raw.githubusercontent.com/Louisvdw/dbus-serialbattery/master/etc/dbus-serialbattery/install.sh

bash /tmp/install.sh

Also switched to nightly/dev with this method.

But: No crashes since yesterday. It looks promissing. :-)
