Amazon is one of the largest smart home players through its Alexa voice assistant and the Echo family of smart speakers and displays. Beyond Echo, Amazon owns Ring and Blink for security cameras and doorbells, and its Alexa platform acts as a central hub that controls thousands of third-party smart home devices. Alexa's broad compatibility and low-cost hardware make Amazon a common starting point for new smart home users.
