Everything is to it. The steps above seem frightening, but you will easily choose it and you will be able to control your smart plugin and the devices you put into it.
I really like how easy is the smart key of Amazon, and that it does not require me a violin with a smart center. (Although the Amazon Echo Plus has one built-in, which does not need much setup). However, it was intelligent that you can add other things like Philips Hue lights and other devices that need more than just an exit to work.
But if you want to use your voice or phone easily to a fan, a holiday light, a coffee or any other simple device with a switchover / shutter, then the Amazon smartphone is a really simple way to do that, not where you are.
