I’m trying to support the development of a custom component, but for some reason I fail to handle Python dependencies. They are in manifest.json, are installed but I still see No module named 'xcomfort' and encounter a failure.
manifest.json looks like this:
{
"domain": "xcomfort_bridge",
"name": "Eaton xComfort Bridge",
"version": "0.1.2",
"config_flow": true,
"documentation": "https://github.com/jankrib/ha-xcomfort-bridge",
"issue_tracker": "https://github.com/jankrib/ha-xcomfort-bridge/issues",
"requirements": [
"xcomfort==0.1.2",
"rx==3.0.1",
"pycryptodome==3.15.0"
],
"system_packages": true,
"ssdp": [],
"zeroconf": [],
"homekit": {},
"dependencies": [],
"codeowners": [
"@jankrib"
]
}
Using: ghcr.io/home-assistant/home-assistant:latest, I can see that they are installed to /config/deps when I try to add the component.
Debug logs:

I can see that xcomfort is installed in /config/deps, but not loaded. So I expect it’s not in $PYTHONPATH.

I’ve added a logging statement in the custom component __init__.py to confirm and found that indeed /deps/config is not in the Python path.

Not sure how this should work for custom components, any guidance would be appreciated here.
