I wake my echo and then grind coffee beans.

That’s likely the path that I’ll end up taking. Everything hue related that I have is Zigbee.

If I use Home Assistant for control and block the Hue hub from the internet, will things keep functioning as they are today?

I like how my stuff works and don’t want them to mess me up.

Make yourself a mod and patch with revanced and you can still see nsfw content. For now.
