Developers and Geeks


You a Geek?

“whose unbridled passion for something, or things, defines who they are as a person without fear of other people’s judgement”? *

Or maybe you just love imagining things and then bringing what you imagined into life. You take a break from it so that you can think about it. There’s always something else you can do to make it better but you never take a shortcut. Although it’s never perfect, you don’t give up trying to make it so. You always do the right thing even when it’s harder.

We started as geeks with a simple vision: every home needs a sidekick like ISY. We invented the first low cost embedded home automation product (ISY26) in 2007. Attracting likeminded geeks has been so important to us that the first thing we did was to put a Web Service Interface on our little resource constrained box. This is when Web Services were only available on servers.

We are still here. We are still here because we believe in our vision; because we get strength from our fellow ISYers; because we believe in doing the right thing even if it’s harder; because we don’t easily give up; and most importantly, because

We are still geeks

And, we would love you to join us. Excitement is guaranteed as is limitless opportunities to quench your thirst for imagining, tinkering, creating, and making. You can literally integrate anything you can imagine into ISY, publish it into our store, and watch it fly.

It may never be perfect but we’ll make it as perfect as possible. Together.

And Tools …

You are finally home! You can use your expertise in REST, SOAP, Node.js, Python, XML, JSON, Docker, Linux, BSD and pretty much any other language/framework binding to communicate with and extend ISY.

And, being geeks, our latest inventions are called Polyglot and Polyglot Cloud (PGC). You will thoroughly enjoy developing Python/Node.js based dockered polys that can be deployed directly from your GitHub repository into Polyglot store and subsequently installed in ISY as native nodes.

But, wait! You see, anything can be a Poly and become a native node in ISY. Anything, literally! For instance, there’s nothing to stop you from making a Poly from a robot or GPIO pins on ESP8266/Arduino/RPi. Or some virtual thing in the cloud. Or even personal holidays. In short, the sky is the limit.

But, again, wait! You see, Polys that do not depend on physical characteristics of the hardware they run on can be deployed in Polyglot Cloud (PGC). As is.

PGC is our integration platform for cloud services things. Simply Brilliant!

And, soon, you will be able to monetize your Poly masterpieces! Stay tuned.


Polyglot is a framework that enables you to integrate literally anything with ISY as native nodes. Currently Polyglot runs on something like RPi.

Polyglot Cloud (PGC)

PGC is our integration framework for things/services that are cloud based. Regular Polys can be deployed into PGC as long as they do not depend on specific hardware features.
