How does “Push to Talk” work?

If you ever find that you’re unable to wake Alexa with your voice, you can still use voice commands using the “Push to Talk” button on your ecobee4. On your thermostat, tap the microphone icon, and then tap the “Push to Talk” icon. Once tapped, you’ll see the blue LED light up. Now go ahead and ask your question, and Alexa should respond.
