Modern Amazon Echo devices know how to talk to things that support Matter, which is a new general protocol (that seems to live more in press releases than reality). But if I want to control a local Python script from my echo, without making the Python script visible to the internet (which cuts out custom skills), doing it with Matter seems a lot better than old hacks like having it pretend to be a PhillipsHue lightbulb. Anybody know about this stuff? Ideally not requiring all of home-assistant.
