I have 2 DIY battery packs.
1 has a RS485 Connection, the other Bluetooth only
they are both connected to an Inverter and i use emoncms for monitoring.
The problem is that i am only able to log and show the pack with RS485 in emoncms
so i have a situation where the panels are producing 1800 Watts, but my dashboard shows only 600 Watts going into the pack with RS485 connection
I need to compute the difference between charging and discharging for the second battery.
e.g Panels doing 1,600 W
Battery A is taking 600 W
Battery B should be 1,600 W minus load minus 600 W
same with discharge.
i can’t find a guide for using virtual feeds, else i would not ask.
