Open-source projects for the smart home, the document archive and the work on GitHub. Each one comes with tests, signed releases, security checks and bots that look after it, and each has a website of its own. The search at the top finds the pages of all of them.

For the smart home and the document archive

The Autodarts board card in Home Assistant: a visit of 115 points with its three darts, T20, S5 and Bull, beside the dartboard.

Autodarts for Home Assistant

Local realtime control of an Autodarts board in Home Assistant: X01, Cricket, party and training games, tournaments and a bot, statistics with heatmaps, dashboard cards and blueprints, games started by voice. No cloud account needed.

Install with HACS Docs

An insurance contract in Paperless-ngx, synchronized on its own into the Nextcloud folders Paperless, Example Insurance, Contract and 2026.

Paperless Sync

A Nextcloud app that mirrors the finished documents of Paperless-ngx into a structured archive in Nextcloud, for Files, the desktop and mobile clients, sharing and the viewer. It can also hand files from a Nextcloud inbox to Paperless.

Nextcloud App Store Docs

The unified search of Nextcloud for invoice: the Paperless documents with their dates and text, below the files of Nextcloud.

The OCR and full-text search of Paperless-ngx in the search of Nextcloud. A result opens the synchronized file right in the viewer of Nextcloud.

Nextcloud App Store Docs

Paperless Sync and Paperless Unified Search are made to work together: the first keeps every finished document of Paperless-ngx as a file in Nextcloud, and a match of the second opens that file in the viewer of Nextcloud.

For maintainers on GitHub

The comment of the issue assistant on an issue: labels, a summary, the likely cause and what would help, and the release that fixed it.

Issue assistant

A GitHub Action that looks after the issues of a repository: a first analysis by an AI that only reads, labels, duplicates, reminders for open questions, and the way from the fix to the release.

Use the action Docs

A terminal that makes a Nextcloud app with copier copy and applies the settings of its repository, above the kinds of projects of the blueprint.

Repo Blueprint

The Copier template all of these projects are made from: tests on every change, a release bot, security checks and the settings of the repository as code, for seven kinds of projects. A bot brings every repository up to each new release.

Support

Questions and ideas belong in the repository of each project; vulnerabilities are reported privately, as its security policy describes. If the projects are useful to you, you can support their development.
