In the updated NODE-RED, the VE.BUS system control node has a value for "VE.Bus state of charge (%)". The docs has limited info: The dbus path is /Soc and the type is float.
What does it do? Does it overwrite the SOC in case you have a better measurement source or does it specify an SOC level for which to enter float (maintaining that SOC level)?
(I've written a flow some years ago to keep the LiFePo batteries in my sailboat from charging to 100% when it's not in use by manipulating the switch settings. It'll then oscilate between 75% and 80% until I throw a switch to charge to 100% before going sailing. Being able to specify a float value by SOC would be a much more elegant solution.)
EDIT: No ESS on this system (a boat.) I see there’s some mentioning of “ESS SOC” around the forum - which seems to act like what I want (the ability to set a desired SOC for the system to reach and then enter float.) Might this NODE-RED item only work with ESS?
