I am running on a Pi 4 with Home Assistant 0.102.3 using Hass.io.

I have the Almond add-on working, however, when starting the Ada add-on I get the following traceback:

OSError: [Errno -9996] Invalid input device (no default output device)

As I wrote on the forum, I am not sure whether this is expected as I do not have a microphone or speaker connected.

These are my audio settings:

Even though I have no output device, still something is selected.

commented

Yeah, a voice assistant without a microphone will not work 🤔

commented

Ah, I had the impression that when I used voice input with Almond, like

That I used Ada for this, but that must be something else then.

commented

Would it be possible to connect Ada to a remote stream, like with Rhasspy?
Should I open a separate issue for this? Or is it better to keep the discussion here?

commented

This one use browser STT (chrome -> google) and send it to our conversation platform.

Ada is a local Voice Assistant they handle hotword and use the platforms/integration of Home Assistant to handle the functionality of a Voice Assistant.

The code is now open for the community to extend it with more functionality. If there is a good use case for hermes, feel free to implement this functionality.

Thanks for the quick answers!

If there is a good use case for hermes, feel free to implement this functionality.

When I get my microphone, I'll start testing and might submit a PR if I decide that the functionality is useful for me 👍
