Your feedback is always important to us, and when you ask for something, we listen. Today, we're excited to announce that "ESP" (Echo Spatial Perception) now works with your ecobee4! This comes in handy when you have more than one Alexa device in your home. With ESP, only the Alexa device closest to you will respond to your command. Now when you say "Alexa" to your ecobee4, Amazon Echo or Amazon Dot, only the device you're closest to will respond. With this latest firmware update, ecobee4 will play well with others and gives you the best experience in whole-home voice control. Rollout has begun and this update will be made automatically. You can confirm your firmware version by going to MENU > ABOUT on your thermostat. If you aren't running version 4.2.0.171 email us at updates@ecobee.com Watch this helpful video about speaking to Alexa and getting the most out of ecobee4.
