The official companion application for openHAB - an open source home automation system. The open Home Automation Bus (openHAB) project aims at providing a universal integration platform for connecting home automation technologies into a single intelligent system. With more than 3000 things that openHAB can connect to, there’s virtually nothing that can’t be integrated. Its advanced rules based architecture allows complete automation using several popular scripting languages (Java Script, Ruby, Python, Java, RDSL, and more ) as well as visual rule designers using either drag and drop interfaces or simple “If / Then” forms. The new openHAB UI allows users to easily build beautiful interfaces customized to their needs. openHAB is designed to be absolutely vendor-neutral as well as hardware/protocol-agnostic.
