Victron Shunt always added to BatteryAggregator

[SlapJackNpNp]

Hello,

first of all, thanks for this tool!

I just set it up with two dalys but i always have the victron smartshunts added to the battery aggregation. My config looks like this:

{ "excludedServices": ["com.victronenergy.battery.shunt1"] } { "virtualBatteries": ["com.victronenergy.battery.virtual1": ["com.victronenergy.battery.shunt1", "com.victronenergy.battery.leastPrecedence"]] }

i tried removing the batteryshunt from the virtualbatteries entry aswell but to no succes. Not sure what i'm doing wrong.

Thank you for your help.

Services mentioned in virtualBatteries are automatically excluded. What are the service names of all your devices (or please attach a screen shot of dbus-spy)?

[SlapJackNpNp]

What exactly is dbus-spy. Do you mean the list of devices shown in the cerbo? Or ist it a command i can execute over ssh?

[pulquero]

Command over ssh.

[SlapJackNpNp]

This is what i get with dbus-spy i hope this helps?

I'm not to familiar yet with all the coding, but i guess in this case, i need to

"excludedServices": ["com.victronenergy.battery.ttyS6","com.victronenergy.battery.ttyS7"]

?

[pulquero]

You want something like this (I may have the shunts the wrong way round)

    {
        "virtualBatteries": {
            "com.victronenergy.battery.virtual1": ["com.victronenergy.battery.ttyS6", "com.victronenergy.battery.ttyUSB0"],
            "com.victronenergy.battery.virtual2": ["com.victronenergy.battery.ttyS7", "com.victronenergy.battery.ttyUSB2"]
        }
    }

So what exactly will this do? Like my goal is to ignore the smart shunts for the aggregator and only use the dalys. Atm i have 2 packs, each with 1 daly and 1 smart shunt. I want ti get the data and the control from the dalys and use the shunts only to check the consumptions while i monitor the system.

Currently the aggregator uses all 4 so i get each current twice.

So yeah how can i get the aggregator to ignore the shunts and only use the dalys?

Thank you very much

[pulquero]

This will combine a shunt with a daly to form a virtual battery - it will take the consumption from the shunt, and fill in any other parameters from the daly so you have the merged combination of the two. So, you'll have a virtual battery for each pack. And the aggregator will just aggregate these two virtual batteries.

Aggregator ---- Virt Batt 1 ---- Shunt
                            ---- Daly

           ---- Virt Batt 2 ---- Shunt
                            ---- Daly

[SlapJackNpNp]

Oooh that sounds amazing. Gonna test that tomorrow. Thank you very much!

[SlapJackNpNp]

Okay, so i added the command you suggested:

{ "virtualBatteries": { "com.victronenergy.battery.virtual1": ["com.victronenergy.battery.ttyS7", "com.victronenergy.battery.ttyUSB2"], "com.victronenergy.battery.virtual2": ["com.victronenergy.battery.ttyS6", "com.victronenergy.battery.ttyUSB0"] } }

I sorted it, so that the BMS and the shunt fit together. That is the only command i hace in the config.json atm. The Aggregator still uses 3 Units somehow tho, meaning that the showed values are not correct. Unfortunately i don't know what the 3rd unit is the aggregator is using.

This is what the dbus-spy shows.

Is there btw a way to name the Virtaul Batteries somehow?

Thank you very much again for the help!

Hi, almost the same isssue, can't succed to exclud my shunt from the equation ? I create the file config.json with nano in the folder specified and try many way to try to exclud my shunt, but no cigar!

I would like to see only my two Daly Bms the Battery Aggregator. please advise

@Marccatamaran So you have one shunt across both batteries? So are you looking to aggregate the two Dalys and then have the result merged with the shunt?

[Marccatamaran]

Yes I have my two Daly BMS on 560ah each and after I have my victron shunt! This one totalise whatever I take from the two Daly BMS!

At the end it would good if I drive my voltage with the Battery aggregator and use the SOC from the victron shunt! The Daly BMS have a tendency to drift on the SOC.

Right now if I charge with 100 amps Each Daly show 50 amps that shut show 100 amps and the batteraggregetor show 200 amps.

Currently this is not possible, but I'll see if I can make some changes to allow it.

[Marccatamaran]

Can you show how to remove the victron shunt from the equation of the Batteryaggragator?

[pulquero]

Yes, for now you can add "excludedServices": ["com.victronenergy.battery.shunt1"],

[Marccatamaran]

Hi, I created the file using nano and paste the "excludedServices": ["com.victronenergy.battery.shunt1"], and reboot the Cerbo GX Still have 3 Battery ?

What I do wrong? Thanks in advance for your support!

If you don't have an existing file then the full contents should be: { "excludedServices": ["com.victronenergy.battery.shunt1"] } See (updated) examples here: https://github.com/pulquero/BatteryAggregator

[pulquero]

Ok, it's here, version 2.2. It is now possible to merge shunt data with aggregated data, example config:

Aggregate all available batteries with additional info provided by a shunt

{
    "auxiliaryServices": ["com.victronenergy.battery.shunt1"]
}
