@Emantor I'm currently trying to install your nix package for python 3.13.
After the backport of a fix yesterday I can install it, but have trouble bringing a usb relay board to work.
The exporter runs NixOS and has this minimal? configuration:
leinestelle-gruppe:
location: leinestelle
HIDRelay:
index: 1
invert: false
match:
ID_PATH: 'pci-0000:00:14.0-usb-0:2'I invoke it from the shell:
labgrid-exporter configuration.yaml
In another terminal (on the same nix machine) I have a coordinator running:
and in the third I invoke the client.
When I ask it to show power devices, it find the usb module lacking.
labgrid-client -c remote.yaml --place leinestelle acquire
labgrid-client -c remote.yaml power get
which produces a stacktrace:
Selected role main and place leinestelle from configuration file

raise AgentException(e)
labgrid.util.agentwrapper.AgentException: ModuleNotFoundError("No module named 'usb'")I'm unsure why this fails but expect the load at runtime pattern to have clashed with nixos isolation.
Whatever the python env of the invocation is, it apparently has no access to the usb module, despite it being installed by the nix package.
Do you have a suggestion for me?
