Amazon "Alexa" is a virtual assistant (artificial intelligence technology), developed by Amazon, that is embedded within Amazon's range of smart speakers (Echo) and smart screen (Show) devices as well as on the web or through an iOS, Android or PC app. Alexa enables the creation of routines that control the actions of smart devices or other apps, e.g. switching off a TV and lights, downstairs, whilst simultaneously switching an upstairs lamp on - All from a single voice command of your choice.
You only need to download the free Alexa app (iOS, Android or Windows) to start developing routines and using Alexa's functionality, however the addition of one or more Amazon Echo's and/or Show's, which are constantly listening for instructions significantly improves the experience.
All the smart products on this page are compatible with Alexa.
