I have Mycroft running on an RPi3, which it shares with Home Assistant. HA currently provides spoken output through my Chromecast which, for various reasons, is the best way forward for my situation. What I’d like to do, and what it looks like I can based on work done these past few months, is use Mycroft as a Home Assistant notification platform. So, instead of speaking directly, HA pipes notifications to Mycroft which sends them to the Chromecast. Likewise, I can eventually hook a mic array to the RPi and talk directly to Mycroft, eventually using it to drive my various automations.
In looking through the release notes, it seems like there is an experimental Chromecast backend. Am I correct in noting that this receives TTS output as well? If so, and if Mycroft can speak through my Chromecast, are there any setup docs? I’m OK with it being experimental and perhaps not super polished. My needs aren’t too great, with my HA installation only generating a few speech notifications per day.
