The Samsung SmartThings hub is a home automation hub that is used to control switches, outlets, dimmers, and sensors in your home. This video explains how the hub works and how to use it for opening your garage door and turning on lights and switches. I am using a z-wave linear relay switch to open my garage doors. I am now using this hub with the new Echo Dot as well as the Logitech Harmony Hub for voice-controlled Home Automation. SmartThings is more flexible and capable than the Wink Hub.
