Solution for this issue:
Five edits across three files. The first adds a guard; the other four are the same substitution (direct index -> .get(key, [])), which behaves identically when the key is present, so hubs with paired children are unaffected.
1. kasa/protocols/smartprotocol.py, in _handle_response_lists
2. kasa/smart/smartdevice.py
3. kasa/smart/smartdevice.py
4. kasa/smart/smartdevice.py
5. kasa/smartcam/smartcamdevice.py
With all five applied, state completes cleanly on an empty hub, the device is usable, and the siren features (test_alarm / stop_alarm) work as expected. Behaviour with paired children is unchanged.

Can confirm, the fix above does work for a H200.
My H200 versions are:
And I have also been getting the same error: RuntimeError: coroutine raised StopIteration during _initialize_children() / _handle_response_lists().
Applied the five changes described above to a local checkout of python-kasa and tested it directly against the H200.
The patched version now completes successfully:
The H200 exposed the expected functionality.

Yes, it works for me too.
