ib.victron's Issues

fail to install

Hello,

i want to test your code, but I it fail to install it.
I use a RP4 with python 3.9.2...
building is okay but install get some error:

Have a nice day

Going deeper with Victron Multiplus Metrics

Hi, I just wanted to share my post MultiPlus Inverter Metrics since I hope it will be useful to other folks trying to monitor their split phase / parallel / 3 phase Multiplus installations via VE.Bus/MK2/3.

https://symbioquine.net/2022-12-31-multiplus-inverter-metrics/

I am cross-posting as an issue here since I started out building on top of izak/ib.victron and perhaps other people will find this issue if - like me - they outgrow its current features.

Feel free to resolve this issue at your discretion.

Cheers and thanks for originally writing sharing this library!

Force inverter switch on/off batteries

Hello,
Your project is very good. Working as expected. Do you know an easy way to add a command we can send to the inverter
so it switches from batteries to AC main and then the opposite.
Lets say I am watching: Battery Voltage 27.03 V. When i see for example voltage 26.0V i want to force the inverter to switch to AC mains. Then later when i see Battery Voltage 27V i want to force the inverter to switch to batteries again.
Yes i know this can be done from victron panel but i would like this done from linux. I have Lifepo4 batteries which i monitor from other linux scripts. Victron charger is off.

Regards,
Todor

mk2 --> usb cable

Hi, does mk2-usb cable a simply uart protocol in the usb side? I want to try read ve.bus from an arduino/esp8266.

My victron doesn't respond in the way this code was written.

Thanks for the nice lib Izak. I've been adapting it to run on my pi to monitor my RV's inverter charger (multiplus 3000) but I can't get the serial protocol to work. It responds to the initial address set command 'A', but from then on all commands return the version buffer. Here's a trace:

I'd update the firmware on it but I don't have a wondoze machine to run the vc connect app.
Have you any suggestions?
thnx
