Der neue Monatsrückblick für Mai und Juni 2026 ist online!

Hi everyone,

I would like to introduce a Kanban adapter I developed myself.

The trigger was mundane. At home, our tasks were spread across sticky notes, two different apps and our heads. I wanted shared task management that feels like a normal Kanban board, but tied into the smart home, so that scripts or my local AI agents can create cards and work through them themselves, and so I can embed the board in my dashboard.

Since I could not find anything suitable, I set out to build a fitting adapter myself.

This is what it looks like:

The features

• Its own web server (default port 8095) – the UI is served directly by the adapter, no iobroker upload needed for UI updates
• Multiple boards with freely configurable columns: name, order, display limit, WIP limit, flags for the "new" and "done" columns
• Cards with title, Markdown description, assigned users, due date (optionally with a time), labels, colour, priority, checklist, link, location and an .ics calendar invite
• Recurring tasks: daily, weekly, monthly, yearly, n-th weekday, n-th working day including public holiday calculation (uses the feiertage adapter if it is installed... sorry, only works with german holidays)
• Drag & drop with mouse and touch, live sync via WebSocket
• Multi-user operation without a login: user list in the instance settings, members per board, and the chips in the header act as a saved person filter
• E-mail notifications through the email adapter on assignment, due date and card events, switchable individually per user and per event, optionally with an .ics appointment attached
• Multilingual (de, en, fr, nl, it), date and time format configurable per instance, light/dark/automatic theme, accent colour and custom CSS

The board runs entirely locally inside ioBroker, which was very important to me, but it still offers inbound and outbound integration options:

• REST API for boards and cards (write access protected by token)
• Inbound webhooks with a separate token per integration, plus sendTo and an action state for scripts
• Outbound webhooks on every event, for example towards Node-RED
• Mirror states per board and per user (cardCount, overdueCount, overdueList …), ready to use in VIS or Lovelace
• iframe-friendly with ?embed=1, plus a dialog that lets you click together filtered view URLs for the Lovelace webpage card or any other visualisation that can embed iframes

An example from a script that creates a card:

sendTo('kanban.0', 'addCard', {
    board: 'family',
    title: 'Change the ventilation filter',
    due: '2026-08-01',
    assignees: ['bjoern']
});

Support for narrow screens (e.g. smartphones)

On narrow screens the columns stack instead of sitting side by side, and dialogs open full screen. To move a card, press and hold it briefly; while dragging, a quick-move menu with the target columns appears.

Installation

The adapter is not (yet) in the official ioBroker repository, so installation goes directly through GitHub:

iobroker url https://github.com/bmueller77/iobroker.kanban

Or in the admin UI via Adapters → Octocat icon → custom tab → enter the URL above. Then create an instance kanban.0 and open http://<host>:8095/.

Requirements: js-controller 6.0.11 or newer, Node.js 18 or newer. E-mails need a configured email instance, and the public holiday calculation optionally uses the feiertage adapter.

As always with GitHub installations: no automatic updates, and updating works the same way.

What you should know

A few points I would rather state up front than in a later thread:

The UI works without a login. Write access has been token-protected since 0.1.1, which fends off third-party websites and scanners, but it is no substitute for network isolation. The adapter belongs on the LAN; for access from outside you should put a reverse proxy with authentication in front of it. If there is enough demand, that feature might come in a later version… ;-)

This is a first project, born out of my own needs. I have tested it extensively, but only in my own environment.

Documentation

Detailed documentation lives in the GitHub repository, organised by instance settings, board, integration and reference:

German: https://github.com/bmueller77/iobroker.kanban/blob/main/docs/de/README.md
English: https://github.com/bmueller77/iobroker.kanban/blob/main/docs/en/README.md
Release for installation (v0.2.0): https://github.com/bmueller77/iobroker.kanban/releases/tag/v0.2.0

Feedback?! – Very welcome

I would be glad if one or two of you took a look. Feedback is explicitly welcome. What are you missing, what is unclear, what behaves differently than you expected, or where has a bug crept in?

Feature requests are welcome too. Perhaps you have sensible ideas for further functionality that never occurred to me.

Note: during development I had support from Claude, above all for the translations of the UI and the documentation, as well as for testing and proofreading. I am saying so because I think it is only fair.
