Hi all,
I was searching for a way to let my echos speak with me and I found a really easy one via command line/shell script on GitHub. German understanding user could also check out Lötzimmer Blog.
It is really easy to get it running. And you can really make some magic with it. I like the possibility to ask for the last used echo and get tts from there. This was what I missed in my old assistent + sonos setup.
Check it out.
