A quick review of Amazon's new Echo Dot 2 (2nd Generation) with a comparison to the Amazon Echo and some home automation. I have the Echo and Echo Dot working with Samsung SmartThings and Nest Thermostat. I also compare the Echo Dot 2nd Gen to the Echo. The New Echo Dot works very well for playing music since it has an aux port. If you ask Alexa to play music, by default it will play from Amazon Prime Music but it also works with Spotify, Tune-in and a few other music services.
Logitech has recently changed the names of their remotes/hubs. Please see below for new naming information:
Harmony Smart Control = Harmony Companion
Harmon Home Hub = Harmony Hub
All of Logitech's hubs can be controlled using the Harmony smartphone app. All of the hubs are also capable of connecting with other smart hubs such as SmartThings, Alexa, Lutron, and Hue.
The Harmony Companion/Smart Control comes with the Harmony hub and the RF remote. The smart remote works through the Home Hub and both of them require an internet connect in order to function.
This video is a review, comparison, and overview of Logitech Harmony Smart Control, Companion, and Harmony Home Hub.
