I am one of the core maintainers of the Home Assistant frontend for the Open Home Foundation.

I add My Home Assistant links for configuration panels and developer tools so documentation and the UI can deep-link into a running instance.

I contribute to Home Assistant core, including the System Bridge, Honeywell Lyric, OVO Energy, and GitHub integrations, plus frontend-related core changes.

I document frontend cards, card features, dashboards, and integrations I maintain in the Home Assistant user documentation.

🤝 The home for everyone who contributes to Home Assistant: code, design, docs, translations, and community.

The home of the default HACS repositories.

Web Awesome's open source components.

A daemon and CLI for Twitch live channels, YouTube uploads, and a watch-later queue in one feed. Notifies when something goes live, serves the feed to local apps over a Unix socket, and includes an Omarchy bar panel. Effect libraries are published to npm and JSR, with Arch, Debian, and RPM packages. Replaces Twitch Notifications.

A terminal client for Music Assistant built with OpenTUI and Effect. Browse players and queues over the WebSocket API, with synchronized local playback, album art in the terminal, and Arch packages for stable and git releases.

Chromium extension that hides and compacts distracting interface elements on supported sites. Fills the page with the video player on YouTube, Patreon, Viva+, and Corridor Digital, trims extra Twitch panels, and toggles per site with a keyboard shortcut.

Capture crashes and errors from your machines, decide which are worth fixing, and suggest fixes. Reads the systemd journal on each machine, redacts and groups crashes, failed units, and out-of-memory kills into issues on one server, with optional local or hosted decision and language models. Includes a web UI and Effect client libraries.

One shared Home Assistant connection for your machine. A systemd user service keeps a single WebSocket open and serves actions, reads, and watches to local apps over a Unix socket. Includes a CLI with bar JSON for status bars, Effect libraries on npm and JSR, and Arch, Debian, and RPM packages.

A bridge for your systems: a cross-platform app for Linux and Windows that exposes system information and control via an API and WebSocket server. Integrates with Home Assistant for monitoring desktops and sending commands.

Herdr plugin and Omarchy panel for the CI and lint status of each workspace. Watches GitHub workflow runs for the current branch and lints changed files when an agent finishes, with sidebar indicators. Open a failed run or lint check, paste it into the original agent, or launch a new agent in the same checkout, or in a fix worktree for CI.

GitHub Actions workflows shared between my projects, including linting, testing, CodeQL, container and language builds, Home Assistant card validation, Dependabot and Renovate automerge, release drafting, and more. Open for reuse and contribution.

Shared Oxlint plugins and configs published as @timmo001/oxlint-rules. Bundles unchanged anti-slop rules with additional generic and Effect diagnostics, plus recommended and Effect-specific configs for consumers.

Omarchy shell plugin for Sennheiser headphones supported by momentumctl. Shows battery and controls ANC, adaptive noise, transparency, anti-wind, Smart Pause, on-head detection, auto-answer, and Comfort Call.

A standalone CLI and read-only MCP server for deterministic repository context. Gives humans and agents branch, pull request, working-tree, stack, tooling, and framework facts in one snapshot, with generated CLI and MCP docs.

Shared Renovate dependency policy for my repositories. One-day release delay by default, two hours for Effect and related tooling, no delay for first-party packages, and coordinated Effect, OpenCode, OpenTUI, Lit, and Oxlint groups. Consumers extend github>timmo001/renovate-config.

Public Arch Linux binary packages for my projects, served from packages.timmo.dev. Add the signed [timmo] repo in pacman; GitHub Actions publishes stable and -git packages to Cloudflare R2, with AUR remaining a source-build fallback.
