Cannot fetch nor input TV channels

[jasonccfok]

Successfully connected via PIN with my new Sony Bravia XR90J and shown as a TV device in Apple Home App. The refresh and fetching function not working and no inputs/channels/apps auto-added to the list.

Inputs/Apps/Commands can be add one-by-one manually via config.json, however, never get a channel successfully shown in Apple Home App no matter put "source": "dvbc" nor "source": "tv:dvbc".

Thanks!
