Home Assistant sends the list of external wake words it knows about with every configuration request. This picks up the ones micro_wake_word can run, downloads them on demand, and hands them to micro_wake_word so they can be activated like a compiled-in model. Set the new http_request option to turn this on. It requires micro_wake_word to be configured, and pulls in the sha256 and json components used to verify a download and read its manifest. How it works: - The advertised wake words are cached on each configuration request, so entries Home Assistant stops sending drop out and their models are unloaded. - When Home Assistant activates a wake word whose model is not loaded yet, the model is queued and fetched by a background task. The wake word is reported as active straight away so the UI reflects the request while the download runs. - Downloads are checked against the size and hash from the manifest, and the model has to use the same feature step size as the frontend. - A model that fails to load is stored as disabled so it is not retried on every boot. - Loaded models are restored after a reboot. The configuration response now comes entirely from voice_assistant, which merges the compiled-in models with the cached external wake words, so the API no longer needs to append them itself.
