The CheerLights color is now set on Discord. This post is from when anyone could tweet a color to CheerLights. Today, use the /cheerlights command on the CheerLights Discord, and see the Learn page for the current API.
The CheerLights project gets a plug in Christopher Mims article, “2014 is the year of the internet of things—no, seriously, we mean it this time”.
Almost everyone who is actually connecting “things” to the internet remains a hobbyist or hard-core geek—the sort of person whose itch for novelty is satisfied by internet-connected Christmas lights that change color when you tweet at them.
