I already have an Amazon Echo or Amazon Dot, how will they interact with my ecobee4?

Your ecobee4 is exactly like having an additional Amazon Echo or Dot and will work seamlessly with other Amazon products. Once Alexa Voice Service is enabled on your ecobee4, you can view your ecobee4 on your Alexa app just the same as your Amazon Echo or Dot. All previously enabled skills will automatically work on your ecobee4.
