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.

When I bought it in February 2015 it didn’t require anything but a local network.

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.
