You’re doing the lords work my dude. There are not enough ways to thank you for your work

If anyone wants privacy while maintaing a smart home, then Home Assistant is the solution. Its not adopted widely because it has a learning curve and it needs a bit (or a lot) poking around to make it work. It also has a voice assistant that is not AI powered ( but it could be supplemented by a local LLM if you really want to). A big rabit hole if anyone is interested to go to.
