Victron - VE.Bus Smart Dongle

The VE.Bus Smart Dongle combines two products in one:
first of all, it is the Bluetooth accessory for the Multis, MultiPlus, MultiPlus-II, MultiGrid, MultiGrid-II, Quattros converter/charger ranges and the Phoenix model series equipped with a VE.Bus port. After installation, it is possible to monitor operation and control the system through the app: change the input current limit and switch between on, off and charger only modes.
It can also serve as a temperature and voltage probe for the converter/charger. It works with all models.
 
For system supervision, this device is a great alternative for use with small boats for which the Color Control GX or Venus GX would be too complex.
