WeIO at MakerFaire Paris

WeIO will be presented at MakerFaire Paris 2015 2-3 of May. http://www.makerfaireparis.com


Plug & Web

Forget software installations. With WeIO your objects contain all necessary tools and applications that give you the power to create their inteligence and modify them anyway you like it, in realtime.


Web & Things

WeIO is a Web of Things platform. It lets you connect and control your objects from any device using only your web browser. Connect easily objects between them or with Internet services like social networks.


Wireless & Less Wires

Forget all your cables. WeIO gives your objects Wi-Fi connectivity, making them mobile and easy to reach, program and control from anywhere you are.

Smartphone & Tablet

Painless control from any smartphone or tablet! Program your web app using your computer browser and launch it right away on the board. Observe and control the board from your smartphone or tablet browser. It’s that simple! Great variety of smartphones and tablets are supported from the early models till the most recent ones



WeIO is made for the lazy ones ;). We visualize all sensor data in realtime on our smartphone from browser. We program from browser, also. WeIO connection from things (even if it’s just one photoresistor) to any smartphone or tablet is instant and visual. Our secret is HTML5!

HTML5 & Python

WeIO uses an Arduino-like API, but in JavaScript and/or Python (both are supported), so it is really easy to learn and start using it.

WeIO programing


Program WeIO on the go from any computer Mac or PC directly from browser using it’s advanced full web code editor and powerful graphic realtime tools.
