This morning my kid asked the voice assistant to "Turn off the computers in this house".
I heard it, thought well that's a strange request but seems harmless because how is home assistant gonna turn off computers.
Me a little while later, "why is shit broken? What's happening!"
Turns out dumb me had adguard exposed to the voice assistant, it switched off all the adguard settings including the DNS rewriting that is the cornerstone of many of my self-hosted services.
I've since revoked that access.
I'm surprised it didn't turn off the voice assistant. It does have the ability to mute itself (for when the kids are using it when they are supposed to be doing something else or are just generally annoying).
