I had no problem importing your diag

[violet nymph]

Hi, thanks for letting me know @lime ember Out of interest - did you already have a node commissioned and visible in the webui dashboard? When I already have a node then the import works. But when I dont have any matter nodes commissioned it fails. I ran the python matter server independently of HA on my dev machine and I think I found a bug in devicecontroller.py

Traceback (most recent call last):
File "/home/ivob/Projects/pip-python-matter-server/venv/lib/python3.11/site-packages/matter_server/server/client_handler.py", line 214, in _run_handler

Yes I have 14 nodes without this new one.

ah that has not been tested so you are right - that is indeed a bug (but an edge case though)

May I ask what is the usecase of setting up a blank server without actual devices ?

[violet nymph]

Thanks @cosmic cloak good to know that it wasnt my stupidity. My use case is remote development of a hassio add-on and I was looking at ways of setting up dummy matter devices on the python matter server.

by the way, I am happy to raise a PR and make a fix for this. but i am struggling to set up a dev environment of the pyton matter server due to python versions (python3.11) and my connected home repo is python3.10. I tried to install the chip whls that I built in the latest project chip repo but I am running into some difficulties which are likely caused by version capability between project chip and the python matter server repo. Is there a particular version / tag of the project chip repo that I should use to build the whls for the python matter server repo?

[cosmic cloak]

Oh you cant build the wheels easily yourself, also you need to respect the python version. We build wheels for linux (amd64 + aarch64) and macos (aarch64)

easiest is just macos (or linux) with a python 3.12 venv
simply run pip install -e ".[server]"

to install all requirements (including the sdk wheels)

and pip install -e ".[test]"

to install the dev/test requirements

But if all you want is fix that one bug I can do that tomorrow as well for you

[violet nymph]

Thanks. I followed your instructions and now have set up a development environment for the python matter server. Let me try to raise a PR and fix for this tomorrow myself as I would be keen to contribute to this great project in any way that I can
