## What it is
OpenZWave is a C++ library that interfaces with Z-Wave networks via a USB Z-Wave controller, letting applications control Z-Wave devices without knowing the protocol details. It includes language wrappers and a minimal example application (MinOZW).

## Use cases
- control Z-Wave lights and switches from my own application
- build a home automation hub that talks to a Z-Wave USB stick
- read sensor values from Z-Wave devices in C++
- integrate Z-Wave device discovery and management into my software
- send commands to Z-Wave locks and thermostats programmatically

## When to choose
- you need a mature, well-documented C++ Z-Wave stack with language wrappers
- you are maintaining an existing integration built on OpenZWave
- you want a free, open-source alternative to proprietary Z-Wave SDKs

## When to avoid
- you are starting a new project - the project is officially unmaintained since 2022
- you need ongoing support for the newest Z-Wave protocol versions and devices
- you prefer an actively maintained alternative such as Z-Wave JS or OpenZWave 2.x (qt-openzwave)

## Facets
- artifact type: library
- maturity: abandoned
- function: sdk, embedded, iot
- domain: iot, hardware
- platform: windows, bsd, cpp, cross-platform
- tags: z-wave, home-automation, usb-controller, smart-home, protocol-library, automation, linux, macos
