Have you ever wished you could control your thermostat simply by voice? No, nor me.
Pictured here is the original Amazon Echo, a mains-powered, Bluetooth speaker with voice assistant (Alexa). The new Echo Dot (without the big speaker) is replacing this device but connects with many other Bluetooth speakers, e.g. Bose, Sonos. The new Echo Tap is a portable (rechargeable battery) version of the above which means no leads but will require charging. You can now link in many devices such as light switches to create a smart home. http://smarthome.reviewed.com/features/everything-that-works-with-amazon-echo-alexa
