So I recently got an echo plus and I love it. I use it for music and controlling lights. I have it in my bedroom upstarts and only control my bedroom lights. So I want to get an echo dot or two for downstairs to control those lights. From what I've read you need a hub to communicate with the lights. But I known the echo plus has a hub and can communicate with lights directly . So my question is can the echo dot control lights if it's in the same house as The Who plus that's acting as a hub?
