Siri no longer has knows anything
Looks like this has been asked hundreds of times before with no useful answers.
Before: "mouse battery level" would tell me the mouse battery level. Now any question to Siri about the hardware at all come back with "I can't do that".
I fact it's a major effort top get anything other that "I can't do that" or "I found this on the web".
