openHAB
Overview
openHAB (open Home Automation Bus) is a vendor-neutral, hardware/protocol-agnostic home automation platform written in Java and based on OSGi. It serves as a universal integration platform that brings together different bus systems, hardware devices, and interface protocols through dedicated bindings. openHAB’s event bus architecture allows designing user interfaces with a consistent look and feel while operating devices from a wide range of different technologies. It also provides powerful automation logic that can operate across different system boundaries, making it one of the most flexible and extensible open-source home automation solutions available.
