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

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.

Portable agent skills following the Agent Skills specification, installable across OpenCode, Claude Code, Codex, Cursor, and other clients. Canonical source for the OpenCode config catalogue, covering TypeScript, Effect, GitHub, Home Assistant, and local workflow skills.

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.

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.

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.

Public Arch/Omarchy dotfiles with GNU Stow and a compiled dot CLI. Machine bootstrap, multi-repo git tooling, GitHub workflow and notification inboxes, Omarchy desktop sync, optional private overlays, and OpenCode agent publishing.

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 standalone TUI, CLI, and MCP server for repo-scoped Markdown notes. Gives humans and agents safe note reads and writes, handoff-tagged notes, and generated CLI and MCP docs.

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.

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.

An Effect v4 SDK for the GitHub CLI. Typed commands for the REST API, repositories, issues, pull requests, and workflow runs, with schema-decoded JSON, streaming, and tagged errors for consumers that already run authenticated gh.

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.

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.

Herdr plugin that draws an animated mascot on the active pane. Cat, dog, and robot packs in pixel and illustrated styles hop when you switch panes, with configurable size, position, opacity, and per-directory pack selection.

Persistently float selected Hyprland windows. Pick a window, write exact class rules into a generated include, and keep stowed configs and Omarchy's shared floating rules intact.

A dashboard for keeping on top of your home: low batteries, repairs, updates, offline devices, and stale sensors. Overview at a glance with room-by-room views, and a summary tile you can add elsewhere.

A terminal UI for Home Assistant built with OpenTUI and Effect. Browse entities by domain and area, search with fuzzy matching, and view favorites from your Home Assistant frontend config.

Omarchy shell plugin that replaces the built-in clock. Popup with a six-week calendar, ISO week numbers, year progress, world clocks, and a time-offset slider for comparing timezones.

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.

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.

Manifest V3 extension that relaunches the current page as an Omarchy app window through omarchy-launch-webapp and a native messaging host. Supports Chromium, Chrome, Brave, Edge, and Vivaldi, with a context-menu flip back to a normal tab from app windows.

Shows upcoming calendar events in a simple list. Pick one or more calendars, choose how far ahead to look, and optionally collapse duplicate events across calendars.

Shows what is using power right now, broken down by room and device. Browse from a whole-home view down to individual entities, with current usage and today's total.

Lets you link to a specific place on a long dashboard. Open a URL with an anchor to jump straight to the section you want.

Adds a forecast strip to tile cards for weather entities. Choose how many periods to show and whether temperatures are rounded.

Shows an entity's state on a tile card, including attributes or extra details like area name. Adjustable text size in the editor.

A tile on your dashboard that opens a panel with more cards inside. Useful for hiding controls or extra detail behind a single tap.

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.

Custom Lovelace strategies that build dashboards from filtered collections of entities, such as temperature, humidity, or batteries, grouped by floor and area. A full dashboard strategy and a section strategy, both with editors.

Shared branding, layout, and config for my documentation sites, published as @timmo001/docs-kit on npm and JSR. Powers the Dotfiles, Up Next, Home Assistant Bridge, and Triage docs, with an agent skill for setting up or changing a site.
