Your life and your house went from one computer to an Internet of things. From tablets to lightbulbs, from sensors to media boxes, everybody gets their own Internet. Today, you have to fight your things. They don’t talk to each other, the apps don’t work, it’s a tower of babel. Our solution — the Thing System — is open source. We’ll talk to anything, you can hack the system, it has an open API.
With the Thing System, you can finally take control of your things.[/quote]
