diebietse / invertergui Goto Github PK

Is there a way (or is it possible to add one) for invertergui to read events from a Victron inverter "NS protection log" (please see attached screen).

This is available on VEConfig3 under the "Grid" tab by pressing the "Show IP (NS) protection log", and is very very useful to diagnose why the heck the inverter turned its mains input off (usually because it went out of acceptable voltage and/or frequency range). I use it all the time while I'm tuning my new generator and the inverter config to work smoothly with each other, and it's a PITA to take the cable out of my RPi4 (where I run invertergui) and plug it into my PC where I have VEConfig3 installed.

It would be great if invertergui could monitor this log either periodically (like once a minute) or on demand, and dump any new events either to stdout or (even better) log it to syslog and/or MQTT.

Please let me know if I can be of any help, for example capturing traffic on the MK3 USB port when the button is pressed in VEConfig3.

Hello, i had successfully build and run invertergui both from source or direct from docker ready image.
I am able to see correct my stats via / , /metrics , /munin
I do not understand how to use Prometheus and Grafana to see more beautiful webpage.
The manual says:

The Prometheus endpoint is at the default /metrics path (http://localhost:8080/metrics).
Sample Prometheus yaml entry:

• job_name: "victron"
  static_configs:
  • targets: ["localhost:8080"]

But is is not clear where to create that yaml, what should be the name and other information.
Also this line is not very helpful too:
"This repos includes a Grafana dashboard in the grafana folder that you can import. This is useful if you are using prometheus to log your data and want to display it in a nice way."

If you can guid me how to import that folder and see more good webpage.

Hi H van Wyk, I wanted to let you know that I have added a link to this project on http://www.victronenergy.com/live/opensource:start.

Very cool that you are doing this!

If you feel it should be different, let me know. Or even better: make an account on our live pages, and make the change yourself.

Best, Matthijs

Hello, I downloaded the latest version of the branch on my raspberry pi 3 and it works, but we have not managed to make it work the right way.
I get the wrong values

multigraph in_batvolt
volt.value 0.00
multigraph in_batcharge
charge.value 0.00
multigraph in_batcurrent
current.value 0.00
multigraph in_batpower
power.value 0.00
multigraph in_mainscurrent
currentin.value 128.59
currentout.value -12.48
multigraph in_mainsvoltage
voltagein.value 207.35
voltageout.value 207.35
multigraph in_mainspower
powerin.value 26662.97
powerout.value -2586.85
multigraph in_mainsfreq
freqin.value 0.36
freqout.value 1.10

Is there any way to ask the investor only the securities I need?

For example, I want to consult only currents and the actual power, I see that with winmon commands you can query variables.
I was thinking of using py.serial by querying the current snapshot in the format indicated in the document (04 FF 'A' 01 00 BB), I have been reading but I still do not know if I am doing the right thing.
I assume the format is fine, but I don't want to fail my inverter when testing.
I don't quite understand how to make my new consultation to bring these values that I tell you.
Saludos my friend and thanks for your contribution

Firstly, let me state that this project is awesome. I am excited about collecting the metrics with Prometheus.

I have an issue with my Victron MultiPlus 24V/3000 using this software. It seems out output the incorrect current and voltage values for outputs when the system is not under load. I am using a MK2 USB adapter.

Example is how it normally looks when not under load:

But every few refreshes it will give the correct value:

When placed under load, it seems to work just fine. Is this something you've seen before?

Thanks

Hi, I downloaded this repository in my raspberrypi (os architecture: armv7l), built the image from the Dockerfile at https://github.com/diebietse/invertergui/ and got this error

(btw i'm using /dev/ttyUSB2:/dev/ttyUSB0 since my mk2 is connected to /dev/ttyUSB2).

I'm asumming i'ts an architecture compatailibty problem, since this container image was meant for amd64 and i'm using armv7l, and because of that, it cant decode the values correctly.

Is there a way to make it work? maybe changing the hex values it's using on the decode part might help, but i'm clueless on how to do it.

Hi,

I have purchased a Victron inverter/charger (MultiPlus 1600VA, 12V Inverter Charger - 1.3kW) and their MK3 USB interface (VE.Bus to USB). I am trying to get your super nice GUI to work with my Multiplus and RPi 4.

I am an experienced python (data science) user, but new to RPi and other programming languages, so apologies if this is a really basic problem.

I have cloned the repository and installed all of the dependencies (i think), then I get stuck at the following and dont know where to go from here:

    pi@raspberrypi:~/invertergui $ docker run --name invertergui --device /dev/ttyUSB0:/dev/ttyUSB0 -p 8080:8080 diebietse/invertergui
    docker: Error response from daemon: Conflict. The container name "/invertergui" is already in use by container "d0adb7a565d8e3cd6e80a6bac6850e2357016be4bc76b3488f3283f7ffa984e6". You have to remove (or rename) that container to be able to reuse that name.
    See 'docker run --help'.

Hi,

just pulled latest master here. previously was using branch for 'scalefixes', now I saw it was merged so I switched back to master.
However now I cannot build:

any idea?

Hello,
is it possible to pass some flag 1/0 to force victron multiplus stop using batteries and later start using batteries ? The idea
is to make it remove switch to AC power and return back to batteries.

The munin output code sends a pointer to a struct over a channel and the immediately writes to that struct at

This causes a race condition and can cause corruption in the munin output. https://github.com/diebietse/invertergui/tree/scalefixes should fix this issue.

I'm so glad that I found your project: I was about to write a golang app to extract metrics from MK3-USB to feed Telegraf -> InfluxDB.

You just save me a few days!

Just a minor UI bug, I don't have an input right now... my generator is off.

Input frequency should be 0 but it's Inf
