Additional SmartShunt for mobile battery expansion

[R.L]

I would like to expand a system with 24V 460Ah gel batteries by adding a 314Ah LiFePO4 battery. The battery should not be connected for charging in winter when temperatures are below 5°C. Although the PV system is very powerful, there is hardly any yield in winter because the weather is worse and many of the modules are shaded. In an emergency, it should remain mobile so that it can be charged at home. The temperature-compensated charging voltages of the gel batteries are a good match for the LiFePO4, provided it is not too cold. I am planning to use 175A/2AWG Anderson connectors to connect the LiFePO4 to the existing system. The LiFePO4 is to have its own inverter and a SmartShunt, so that its data can be displayed in VRM. To display both shunts in VRM, I am planning to install Dbus-aggregate-smartshunts on the Raspberry Pi 4. Or is there an alternative? I would now like to ask users who use Dbus-aggregate-smartshunts: Is it possible to view the temperature history of a sensor connected to the new shunt as a chart in VRM/advanced? However, the charging voltage of the MPPs must not be affected by this sensor. Can the temperature sensor be selected so that only the temperature is displayed, without changing the MPP voltage?
