This fix installs a new thread to monitor the state of the original scraping thread. If scraping thread dies, it verifies that it did not because the scraping was intentionally stopped by calling stop_scrapping. When restarting the scrapper, it first calls the bluetooth reset lambda function that was passed in the class contructor, such that bluetooth is ready to make a proper connection. * Fixes #916 #916 * Added Venus OS version to logfile * Fix #840 #840 * Small code formatting fixes * Optimized reinstall script.

Describe the problem
Hello
I have a problem and can't get any further.
I have an 18S battery pack with a Jiabaida AP21S002 connected to a JBD-UART-TOOLS-RS485 smart bms rs485 to the USB port on the Raspberry, and a Multiplus 2 5000 with the MK3 adapter also on the Raspberry. Venus OS configured as ESS.
If I disconnect the battery pack from the Raspberry and switch on the Multiplus, the battery is discharged in the ESS menu Set Gridpointhave I set e.g. -50 watts that works.
But when I connect the battery pack to the Raspberry and switch on the Multiplus, the red low battery LED on the Multiplus lights up and switches off the inverter. Attached photos

iIs it normal for the DCL discharge current limitation to show a minus value?
