I use Home Assistant Voice as my phone's default voice assistant. When I press the voice assistant button on the Venu 3, it says "Connecting to voice assistant" and eventually "Failed". But my phones voice assistant does start, phone screen wakes up and it does start to listen on my phone! - Just need the assistant to start listening and responding on the watch.

I especially bought a Venu 3 in hopes that I could use the HA Voice as my assistant with it, and it seems close to working. I am not sure if it's the watch firmware, or the HA android app which needs improving but seems like there is just a small missing puzzle peace to have this fully functional. https://github.com/home-assistant/android
