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.

I've pooped in your soup and removed the poop when you got angry. You're still gonna eat the soup, right?

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