Awesome Open Source

This project is closing its doors. With the advent of using a.k.a. ozwdaemon there is not much more I could wish for (let's say they stole, my idea if anyone is asking 😄). In good open-source fashion I'll better invest into these projects instead of re-inventing the wheel. It was a short, but fun ride...

Z-Wave Core - Complete, flexible, pluggable

  • Maintain, troubleshoot, investigate the details of your Z-Wave network
  • You are simply looking to (finally) replace ozwcp to maintain your network hassle-free? here you go!
  • Access to your network from any automation with REST or publish your network as MQTT! (not yet available)

Buy Me A Coffee Or Beer

The current status:

  • Z-Wave backend / REST API: beta

  • Browser Frontend: alpha

  • exposing your Z-Wave network as MQTT client alpha, not for daily use, yet

    • Activating mqtt (within HA) and its discovery, allows full GUI based configuration
    • Within zwave-core just run once the network is ready, visit: http://<my_zwave_core_ip>:8123/mqtt


  1. start somewhere, e.g., cd /tmp

  2. git clone [email protected]:daringer/zwave-core.git

  3. make sure you've python > 3.x installed

  4. install venv using pip: python -m pip install venv

  5. create a fresh virtual environment and activate it:

python -m venv /tmp/zwave_core_venv
source /tmp/zwave_core_venv/bin/activate
  1. install the requirements:
cd /tmp/zwave-core
python -m pip install -r requirements.txt
  1. locate your essential Z-Wave files and copy them into the zwave-core directory (this makes sure that you'll change nothing within your current Z-Wave using tool):
# for example for home-assistant
cd ~/.homeassistant
cp zwcfg_0xf5b17667.xml pyozw.sqlite zwscene.xml options.xml /tmp/zwave-core/
  1. locate (and determine) your openzwave installation (flavor), see at openzwave. For me, I prefer the system-wide as having open-zwave installed through my pacman-ager. So for me its: /etc/openzwave

  2. check if your controller serial device (something like /dev/ttyACM0) is writeable

  3. simply run:

cd /tmp/zwave-core
python zwave_core/
  1. start a browser and visit:

Now to start the network, just make sure that the 4 input fields in the top left are correct. Controller device /dev/ttyACM0, openzwave database directory /etc/openzwave, user-dir is our current workdir, where we copied the openzwave files to for safety: ..

Once done click "ON" in the top left corner and wait while watching the event-log being populated by the tasks the controller is executing...

The Vision

ZWave-core shall---as the name suggests---be the core component for the interaction with Z-Wave devices and the network. Providing a highly transparent and accurate interface into the Z-Wave protocol and not hiding any detail. Using a REST API this transparency is delivered in a platform independent, easy accessible way.

A dynamic, web-based and reactive interface is exposing this REST API to the browser, serving as a clear window into the Z-Wave world. In order to transport the high dynamic of the Z-Wave network, websocket-based push is a must allowing the receiver side to not miss any information within the network with the smallest possible latency.

In contrast to this plain, bare-metal approach the major distinguishing feature will be the MQTT layer, which introduces a abstraction layer between any home-automation system and the Z-Wave network in order to seperate what does not belong together: physical and functional layers. While the former is deployable standalone, without prior knowledge of the surroundings despite the Z-Wave network itself, the latter has the freedom to not care about the physical layer at all and focus on the functional, end-user focussed challenges. So, in simple words zwave-core provides a Z-Wave to IP bridge allowing simplicity in Z-Wave management bridging the gap between WiFi and the ISM band.

Browser Frontend ...


There are several ways to access the zwave nodes and entities.

  • zwave/raw/<node_id>/# will provide you an extensive list about all lan-devices, including c onfigs, read-only, ...
  • homeassistant/<component type (e.g., sensor)>/<node_id>/state#' will be populated automaticly
  • there will later also be the option to change how a specific device/entity is exposed to the outer world (providing the means to realize fixes/abstraction, alredy within zwave-core to keep home-assistant free from unneeded clutter.






full node view, any possible detail on one screen, directly editable, instant feedback, websocket driven event log in the top right corner

controller view, less configuration, full ajax frontend (oczwp-replacement), full REST-api already available
