I also tried to find a descent voice control. I thought GH was somehow fast enough for me but, my priority to get everything local has increase. So I have pur SmartThings buttons and Lutron buttons everywhere. Got also old phones that I use with dashboards always on.
I’m using also tts but somehow, HU needs to access google to get the tts back in mp3. So I’m working to make all the mp3 I want to replace the tts commands. Soon, I’ll be 100% local.
If we find a proper LOCAL voice command, I’ll jump into it.
I’ll follow this thread...
