The Victron Energy BAM030712000 BMV 712 Smart Battery Monitor with Bluetooth offers two monitoring channels. The main channel monitors your house battery. The second channel can be used to either monitor the temperature or the voltage of an auxiliary battery, but not both simultaneously. One option to monitor the voltage of your auxiliary battery is to add a a separate gauge. Another solution is to can find a different way to measure the battery temperature so the second channel is available to measure voltage. If you own the Cerbo GX, it can be fitted with a temperature sensor. We also have Ruuvi temperature sensors and the Victron Smart Battery Sense.
