The Amazon Echo Plus (2nd Gen) and Echo Studio are more than just conduits for music and Alexa commands. Each device has a Zigbee smart home hub hiding within that plump, plush exterior, and that makes it compatible with thousands of smart home devices that might otherwise need a special hub to function. These are the best smart home devices to pair with one of Amazon's smart speakers, whether they use Zigbee or just have Alexa compatibility built-in. Many of these devices also work directly with all of the other great Echo devices through Amazon's Certified for Humans program.
