Alexa works as a smart-home controller, so it can recognize and work with multiple devices from multiple manufacturers. An Alexa device such as an Echo or Echo Spot is an example of such a controller. Devices Alexa can control (like thermostats, speakers, TVs, and so on) just have to be compatible. You must make sure you get smart-home devices that are compatible with your controller, so be sure to buy items that are Alexa compatible.
