Hi all,
I build a proxy battery based on victronenergy/dbus-systemcalc.py/scripts/proxybattery.py that takes the information from two BMV-702's in the system here and combines a couple of values. It averages voltages and SOC and it adds amps as the two BMV-702's are used on two parallel battery banks. As you can see in device-list.png, the new (virtual) battery monitor shows up in the Device list with the expected values. So far so good.
One of the reasons for this exercise was to be able to display the DC loads. As you can see on multi-selected-as-monitor.png, the DC loads are not there when the Multi is selected as the battery monitor, which makes sense: the Multi doesn't know about DC loads. When I select one of the BMV-702's as the battery monitor, I do see the DC loads, as expected, but the battery values shown are only those as measured by that one BMV-702 and thus only represent one of the two parallel battery banks.
When I select the new fancy virtual battery monitor as the Battery Monitor in Venus (see select-battery-combo-as-monitor.png) the main display looses all information.
Any suggestions?
kind regards,
Jan
New proxy battery shows up in the Device List as "battery.combo":
battery.combo values (V averaged, A and W added)
Multi selected as Battery Monitor (no DC loads):
One of the BMV's selected as Battery Monitor (battery power and amps only from one of the two parallel battery banks):
Selecting battery.combo as Battery Monitor:
Main display missing all values:
