KNX panel for Home Assistant

KNX UI

This is the KNX panel for the KNX core integration in Home Assistant. It provides a user interface for interacting with the KNX integration.

Features

• Info:
  • Get an overview of your current KNX installation state (shows if connected to the Bus, which XKNX version is running and the currently assigned Individual address)
  • Upload ETS project file (which is used in the Group Monitor to provide destination names and DPT interpretation) and delete it again from Home Assistant.
  • Get key information about the parsed ETS project which has been uploaded
• Group Monitor: Use the interactive bus monitor to view all incoming and outgoing telegrams on the bus.
• ETS Project: Displays the Group Addresses provided via ETS Project in a tree view

Development

If you check this repository out for the first time please run the following command to init the submodules:

$ make bootstrap
...

Development build (watcher)

$ make develop
...

Production build

$ make build
...

Update the home assistant frontend

Replace latest_tag with the current release tag.

$ cd homeassistant-frontend
$ git fetch
...
$ git checkout latest_tag
...
$ cd ..
$ rm -f yarn.lock
$ node ./script/merge_requirements.js
...
$ script/bootstrap
...

Testing the panel

First of all we recommend to follow the instructions for preparing a home assistant development environment.

You can test the panel by symlinking the build result directory knx_frontend into your Home Assistant configuration directory.

Assuming:

• The knx-frontend repository is located at <knx-frontend-dir> path
• The home-assistant-core repository is located at <hass-dir> path (Remark: per default the Home Assistant configuration directory will be created within <hass-dir>/config)

$ ln -s <knx-frontend-dir>/knx_frontend <hass-dir>/config/deps/lib/python3.xx/site-packages/
$ hass -c config
...

or on a venv-install

$ cd <hass-dir>
$ script/setup
# Next step might be optional
$ source venv/bin/activate
$ export PYTHONPATH=<knx-frontend-dir>
$ hass
...

Now hass (Home Assistant Core) should run on your machine and the knx panel is accessible at http://localhost:8123/knx.
