This page is a living (for now) manual for the SmartLife RGBW controller. I say living, because I am still developing on it as I find new features to add or bugs to fix. Of course, it was meant to be used with SmartThings, but it does have a web interface and can be used independently.
Another crowd funded device, Strips by Sensative is an ultra thin Z-Wave door / window sensor that is meant for those that are sick of ugly, blocky sensors that typically sit on your door or window frame. I finally got my hands on one and have spent a few hours testing the device to see how it compares to the multitude of sensors that exist in the home automation market.
This is a wifi relay that can be found for as low as $5. I have had a few of these up and running for a little while now and they are working great. They can even support instant status updates (notify SmartThings on state change) when the switch is toggled by pressing the button, and are really quite simple to setup.
