+==== 5.3 Changing settings & other remote commands ====
+See here: https://github.com/victronenergy/venus/wiki/dbus-api.
+That API allows to read and write VREGs. See MPPT, BMV and other HEX Protocol documents on our white paper section on the website for more information. Once you understood it all; its possible to reset a BMV too 100% with a one liner from the command line, ie "dbus -y com.victronenergy.battery.ttyO1 [find the right path] SetVreg [VREG] [DATA].
+The API will be used for a feature thats in progress: remotely changing settings of MPPTs, BMVs and other products connected to a GX device on the internet.
