Honestly is there any IoT brand that we can trust long-term? Maybe IKEA stuff?
For home audio, Sonos is great. Their voice assistant is completely locally processed.
Tangential PSA: Red Sea (aquatics) does/did this too. I can't control the lights on my fucking aquarium without all four of them being connected to the internet over wifi and managed through an account registered with an app with location sharing enabled. Only the iOS app worked; the Android version was completely broken.
The app lets you group lights and model the lighting curves however you want but there's no reason this couldn't have been done over Zigbee. I assume my LAN is now part of some Mossad botnet.
