The SmartShunt is an all in one battery monitor, only without a display. Your phone acts as the display. The SmartShunt connects via Bluetooth to the VictronConnect App on your phone (or tablet) and you can conveniently read out all monitored battery parameters, like state of charge, time to go, historical information and much more.
Alternatively the SmartShunt can be connected and be read by a GX device. Connection to the SmartShunt is made via a VE.Direct cable.
The SmartShunt is a good alternative for a Victron BMV series battery monitor, especially for systems where battery monitoring is needed but less wiring and clutter is wanted.
The SmartShunt is equipped with Bluetooth, a VE.Direct port and a connection that can be used for: monitoring a second battery, midpoint monitoring or a temperature sensor.
The SmartShunt is also VE.SmartNetwork compatible allowing it to wirelessly share information with other compatible Victron devices via a Bluetooth Smart network.

I have a 12v 240Ah services battery, a 12v 240Ah starter battery and a 12v 140Ah inverter battery; if the starter battery fails I can switch to the services battery to start the engines. The biggest load is the bow thruster at 6kW (on the services battery)vnext would be the engine starter which is rated at 2.5kW. I want to monitor the house battery fully and the inverter battery for voltage only. What size of Victron shunt do I need, 1,000A or 2,000 A? Thanks.
Thanks for your question about sizing the SmartShunt. Assuming that you are not charging the service (house) battery with more than 6,000 watts, which would be very unlikely, then your largest load of 6,000 watts is the determining factor in sizing the shunt. Doing a little math; 6,000 watts / 12 volts = 500 amps. You could very safely go with the 1,000 amp SmartShunt and even if you ran the bow thruster and started the motor with the service battery, at the same time, plus other miscellaneous house loads you would still be below the 1,000 amp limit of the shunt.
The SmartShunt is easily configured the way that you described with the services (house) battery monitored fully (including the State of Charge in %) and the inverter battery monitored for voltage. You just set this up in the free VictronConnect app when you configure the SmartShunt.
Another possiblity is to add a second SmartShunt, maybe the 500A version depending on your inverter peak draw, for the inverter battery and then use that SmartShunt to monitor the voltage of your start battery, with the included voltage sensing wire, and get the optional temperature sensor to monitor the temperature of the house battery using the house battery SmartShunt.
