As the OpenHAB website says…
The open Home Automation Bus (openHAB, pronounced ˈəʊpənˈhæb ) is an open source, technology agnostic home automation platform which runs as the center of your smart home!
Some of openHAB’s strengths are:
- Its ability to integrate a multitude of other devices and systems. openHAB includes other home automation systems, (smart) devices and other technologies into a single solution
- To provide a uniform user interface and a common approach to automation rules across the entire system, regardless of the number of manufacturers and sub-systems involved
- Giving you the most flexible tool available to make almost any home automation wish come true; if you can think it, odds are that you can implement it with openHAB.
