Nest Learning Thermostat

We might call a device "smart" if it connects to Wi-Fi and has an app, but there are smart home devices that can learn and adapt based on your usage patterns. Nest popularized the concept with the Nest Learning Thermostat. The US-only $250 thermostat learns your temperature preferences based on your usage history and adjusts accordingly.

Here's a collection of other smart home devices that similarly learn from how you use them, hopefully becoming more helpful in the process.

Nest Thermostat E

The $170 Nest Learning Thermostat E is the newest, most affordable member of Nest's thermostat family. It has a plastic shell, rather than the original's metal one, but Nest kept the smarts and learning capabilities intact. It can learn your preferences over time and adjust the temperature for you as you come and go, just like every other Nest Thermostat.

Amazon Echo Plus

The Amazon Echo popularized the concept of the voice assistant-powered smart speaker. Amazon recently made its speakers even smarter as its digital assistant Alexa can now learn your voice. Train it to recognize your voice and Alexa can respond with a personalized news briefing, play one of your personal music playlists, or use your voice to authorize purchases. That voice recognition update applied to almost all of Amazon's smart speakers, including the pictured Amazon Echo Plus ($150).

Amazon Echo Look

The $200 Amazon Echo Look goes one step further than the other Echo speakers and learns your fashion preferences as well as your voice. Take a couple of full body selfies if you're deciding between outfits, and the Look will use a combination of its own AI and compiled advice from stylists to help you pick what to wear.

Google Home

Amazon popularized the smart speaker, but the $130 Google Home was the first to have voice recognition. You can train the assistant in Google Home (just called Google Assistant) to recognize up to six different voices.

Sleep Number It

Sleep Number's smart mattress learns about how you sleep and makes recommendations accordingly. The $1,100 mattress tracks how restless your sleep is, and shows you that data over time. If you connect it to your Fitbit or your Nest, you can learn about how temperature and exercise affect your sleep and the mattress will give you recommendations to help you find a more restful slumber.
