Smart dongle from Victron is a Bluetooth accessory for exchangers/chargers that can monitor operation and control the system. In addition, it can also function as a Voltmeter and Thermometer unit.
Bluetooth accessories for exchangers/chargers: Multi, MultiPlus, MultiPlus-II, MultiGrid, MultiGrid-II, Quattro and Phoenix Exchangers with a VE.Bus port. The VictronConnect app can be used to monitor operation and to control the system: change the input current and switch between Off, On and Charge-Only mode.
Can also function as a Voltmeter and Thermometer unit for exchangers/chargers. It works for all models and is particularly useful in connection with the MultiPlus-II, which does not have a terminal for changes in voltage or temperature.
Smart dongle is a good alternative for monitoring in motorhomes, small yachts and caravans, where Color Control GX or Venus GX becomes too much.
