Installing the Nest Thermostat is a great step towards making your home a smart home. If you have an Alexa device, like an Amazon's Echo Spot, Echo Show or Echo Input, you can make your Nest Thermostat voice controlled through Alexa. The process works with non-Amazon Alexa devices, too, like the Facebook Portal. Here's how to connect Alexa to a Nest Thermostat and why you should.

These instructions work with the Nest Learning Thermostat Generation 2 and 3, and the Nest Thermostat E. In Europe, Alexa is not supported on Nest Thermostat E.

Why Connecting Your Nest Thermostat to Alexa is a Good Idea

Alexa and Nest can make a great team. Voice control through Alexa can be useful when you don't (or can't) get up to change the temperature and you can't find your phone to use the app. This is a particularly good system to set up for older relatives with mobility issues that can remember simple Alexa commands, but don't like using apps.
