"Self healing" doesn't sound like a feature to me. It sounds like the product so regularly borks itself it needed nasty safegaurds put in to not, and it was done in a weird way that's annoying to diagnose and fix. Your most stand out feature being it doesn't break it self isn't great. Otherwise, it's what? Fancy on-prem Alexa? Why wouldn't I just setup Home Assistant Voice?
I suspect normal HN readers aren't your target market, but I don't really see who is?
