Running python matter_server.server

Configuration
1

Unfortunately, I cannot use HA as my base OS so I am trying to run the python-matter-server on my Pi.

Unfortunately, it fails to start effectively. I am not sure if things are not properly configured (notice the write error near the start) or there is a missing a dependence associated with chip-repl?

Prior to this I have been running chip-tool and that is having problems with --storage-directory for persistent configurations and I wonder if this might be related.

Any insight?

thanks

On my install ther file permission were not properly set for some reason. Make sure data folder and files has correct permissions

THANK YOU. I created /data and set its ownership to pi:pi which is how I am running the server. That seemed to allow me to write the configuration files there. (Is there a way to specify a location different than /data for the output files?)

I then hit another roadblock where chip-clusters was a different version than chip-core. I uninstalled and reinstalled and that seems ok.

fwiw, when I installed things were incomplete so I slowly built up the components. I started with a base Ubuntu with some apt packages I need and then added the following to get to where I am now. Does this seem right to you? Am I missing something that I have not yet realized?

mkdir .venv
python3 -m venv ~/.venv/general
source ~/.venv/general/bin/activate

sudo apt install cmake libcairo2-dev libdbus-glib-1-dev libgirepository1.0-dev
pip install home-assistant-chip-core
pip install home-assistant-chip-clusters
pip install cryptography
pip install python-matter-server
pip install zeroconf
mkdir /data
sudo chown pi:pi /data

python3 -m matter_server.server

I run the server in docker so I don’t deal with the details. Just simple docker run and works.

I also don’t have ipv6 on my network so trying to figure that out.
