Spook is a custom integration for Home Assistant that extends a Home Assistant instance with a set of extra tools, aimed at people who already run Home Assistant and want more capability without forking core components.

What it is

Spook is a Python custom integration for Home Assistant, distributed under the MIT licence and maintained primarily by Franck Nijhof, who set up the original repository. It loads into an existing Home Assistant installation as a custom component rather than as a replacement for anything in Home Assistant itself. The project describes itself as adding "a huge set of scary powerful tools" to the instance, and its full documentation lives at spook.boo rather than in the repository README.

The concrete problem it addresses is the gap between stock Home Assistant and the specific configuration or automation behaviour an operator wants. Instead of editing Home Assistant core, maintaining a fork, or writing bespoke scripts per instance, an operator installs one integration and gets those tools in place. Spook is explicit that it is not affiliated with, endorsed by, recommended by, or supported by the Home Assistant project, and that it is provided as-is without warranty. The repository is tagged across a wide set of Home Assistant topics, including home-assistant-config, home-assistant-configuration, home-assistant-custom, and home-assistant-integration, which reflects that positioning as a config and automation add-on.

Key capabilities

• Ships as a Home Assistant custom integration under custom_components/spook, so it installs alongside a stock instance instead of replacing core components.
• Distributed through the Home Assistant Community Store, indicated by the hacs-integration topic and the related home-assistant-custom and home-assistant-component tags.
• Adds extra tooling to a running Home Assistant instance, described in the README as extending the instance with a large set of tools.
• Handles localisation through Weblate, with translation files kept under custom_components/spook/translations/ and licensed CC0, separate from the MIT-licensed code.
• Targets Home Assistant configuration work, matching the home-assistant-config and home-assistant-configuration topics.
• Sits in the home automation space broadly, with home-automation and the playful home-destruction topics applied to the repository.
• Maintains public documentation at spook.boo covering the integration's tooling beyond what the README shows.

Who uses it and how

• Home Assistant operators who want additional tools without patching or forking Home Assistant core.
• HACS users, since the integration is published as a HACS-installable custom integration rather than a core component.
• Automation-focused setups, given the repository's Home Assistant automation, configuration, and custom-integration tags.
• Translators without programming background, who contribute localisation through the hosted Weblate project.
• Contributors following the separate guidelines at spook.boo/development, working alongside the original author and the wider contributor list.

Getting started

Install it as a Home Assistant custom integration, available through the Home Assistant Community Store, with the full setup and usage documentation at spook.boo.

How it compares

No list of paid products replaced by this project is provided, and the facts name no comparable tools, so on the evidence available Spook stands alone in this registry.

When to use it — and when not to

Use it if you already run Home Assistant and want extra tooling as a custom integration rather than a core change. Do not pick it if you are outside Home Assistant, if you need vendor-backed support, or if you require an official Home Assistant component, since the project states plainly that it is not affiliated with, endorsed by, or supported by Home Assistant and ships as-is without warranty. Note the trade-offs: 29 open issues, repository text that is thin on detail compared with the external documentation, and localisation that the project itself admits is incomplete.
