## Observation
In a clean openSUSE Tumbleweed container I installed just mygnuhealth just to
check if all necessary dependencies are provided and I found mygnuhealth
eventually fails with "ModuleNotFoundError: No module named 'bleak'":

```

```

## Steps to reproduce
* Run `podman run --pull=newer --rm -it
registry.opensuse.org/opensuse/tumbleweed sh -c 'zypper -n in mygnuhealth &&
mygnuhealth'`


## Expected result
mygnuhealth should fail with clear error messages (which might already show up)
but should not fail with a not found module


## Suggestions
* Obviously there is no good realistic use case behind running mygnuhealth in a
headless container but maybe this just needs simple fixing of package runtime
dependencies
