Learn more about Hunches.

Thermostat Hunches

Enable Thermostat Hunches in the Alexa App. If Alexa has a hunch nobody is home or everyone is asleep, she can adjust the thermostat automatically.

Here's how it works. When your phone leaves your home area and nobody interacts with Alexa for a while, Alexa might have a hunch nobody’s home. If no one interacts with Alexa for a while at night, she might have a hunch everyone is asleep. When someone interacts with Alexa or uses smart devices, she can tell that someone is home. Alexa learns from your daily interactions and improves over time.

You can also help Alexa know when you go to bed or leave home by saying, “Alexa, goodnight.” or “Alexa, I’m leaving.”
