Battery Section : Capacity, Installed Capacity and ConsumedAmphours

[sonny1985]

Hello :)

Before im causing some mistakes in mathematics :D, i have questions about this 3 Points in the "Battery" section

Lets say "Installed Capacity" =280 Ah (This value never changes - i just deliver it always with the rest like meterdata every 5 seconds)
"Capacity" = The actual Rest Capacity of the battery (i can deliver from the BMS to mqtt)
ConsumedAmpHours = Installed Capacity - Capacity (i calculate by myself and deliver via mqtt)

Am i right here ? :)

I plan to add 2 Battery Systems, 2 Daly BMS (via NodeRed and MQTT), are they aggregated automatically , or must i do that with this BatteryAggregate Github Project , which i found while researching ? Or is this step unneccesary ?

I run Venus OS on a Raspi4B, Inverter is a Multiplus II, also present a SmartSolar MPPT150/45 and 2 16 Cell Lifepo Battery Systems, Meter i use Shelly3EM - Multiplus configured as ESS.

Greetings from Europe , have a nice weekend :)

Hi @sonny1985,
I'm sorry no one has answered you sooner. The config for Battery was community provided and so I don't have any real experience with this. My best advice to you is to run dbus-spy, find the attributes in question and enter some values by hand. Then look at the GX device and VRM to see if the values you have entered manually are appearing as you expect. You can run dbus-spy directly from the venusos command line (via ssh).

Best regards
Martin
