What version of VenusOS are you running on your GX device

3.31 from what i understand

Does this issue occur during installation or at runtime ?

Installation

What is the issue you are actually experiencing?

When running the install script i run against following error, its the latest version as prescribed in the readme on this repo:

I am trying to run this on a brand new Multiplus II GX version. do not know if this has to do with it. When i do the last step catting rclocal this seems fine.

If this is not installation related, what does the status payload look like that you are publishing to the driver to register your device?

No response

Relevant log output

I'm unsure why you are getting this error as DataClasses has been added as a dependency in requirements.txt. I would like to see the full log from the setup.sh.

If you just want to get up and running quickly please check the troubleshooting section in the README.

Troubleshooting

during installation

If you receive an error during setup that includes the lines

ModuleNotFoundError: No module named 'dataclasses' Try running the following before running the setup.sh script again.

opkg install python3-modules

I'm also unsure what this log entry refers to:

substitutions: -sh: substitutions:: command not found root@nanopi:/data/drivers# device_name: "esp32_DSMR"

Can you say what was happening here?

[devilmastah]

Oh sorry, the last part should not have been included i accidently copy pasted some text in my putty window after the setup :) I updated the initial comment. I will try the opkg command.

One last thought from me is about using this on Multiplus II GX. I'm not sure how much RAM the venusos has available to it on the Multiplus GX. Keep an eye on system stability. If you get unexpected reboots you might not have enough RAM to support additional drivers etc. I had a similar issue with my original CCGX.

If this happens i will post it here so you know :) Thought it was worth a try. dataclasses problem is solved, i completely missed it in the documentation

@freakent just to let you know, its been running perfectly stable for the past 9 hours on a Multiplus-II 3000 GX. In combination with the esp project https://github.com/NuKeMtje/ESPHomeDSMRVictron this saved me 100 bucks on a energy meter + extra cabling effort :)
