A simple service for top balancing LiFePO4 batteries with a Victron MultiPlus-II with a constant current

	#!/usr/bin/env python3

	"""
	A class to put a simple service on the dbus, according to victron standards, with constantly updating
	paths. See example usage below. It is used to generate dummy data for other processes that rely on the
	dbus. See files in dbus_vebus_to_pvinverter/test and dbus_vrm/test for other usage examples.

	To change a value while testing, without stopping your dummy script and changing its initial value, write
	to the dummy data via the dbus. See example.
