Alexa works with more smart home devices than any other platform — over 100,000 officially. These are the best in each category based on real testing, ranked by reliability and value.

Hub needed? For most products: an Echo Dot ($50) is sufficient as your Alexa hub. Some Zigbee devices also need the Eero Pro 6E or Echo Studio.
