Home Assistant

Home Assistant

Integrated build prompt · IoT and smart home · Product, UX, UI, frontend, SEO/AEO, performance, and QA in one build specification.

When to use this prompt

Use this document when you are planning, designing, or building a product where monitoring connected devices matters. Study the public information architecture of Home Assistant ↗, but reinterpret it for your own problem. Do not reproduce its logo, copy, images, proprietary assets, or pixel-level layout.

• Reference service: Home Assistant
• Core entities: devices, rooms, and automations
• Primary risk: real-time status, permissions, and offline states
• Starting interface direction: real-time control board · calm and trustworthy · medium information density · space or project switcher -> state cards -> direct control -> automation · #41BDF5 · Home Assistant

Public interface design analysis

• Reference basis: These are recurring visual and structural patterns from public landing screens and representative task flows. Verify the current live capture because services change over time.
• Interface archetype: real-time control board
• Tone and manner: calm and trustworthy
• Information density: medium
• Color strategy: restrained brand accents on neutral surfaces (#41BDF5)
• Navigation model: sidebar-led context switching
• Structural sequence: space or project switcher -> state cards -> direct control -> automation
• Reusable patterns: room tabs, device card, toggle control, automation list, offline state
• Independent application rule: Use the order and decision principles only. Do not reproduce logos, copy, imagery, icons, or proprietary screen composition.

Copy-ready prompt

Act as a senior product designer, UX strategist, frontend architect, and technical SEO lead.

Create an implementation-ready product specification and, when requested, production-quality code for [Your product name]. Use Home Assistant (https://www.home-assistant.io) only as a reference for information architecture and decision flow in a product designed for monitoring connected devices. Do not copy the service's brand, logo, wording, images, protected assets, or exact screen composition.

Project context:
- Target users: [Primary users and context]
- Problem: [Problem they need to solve]
- Core features: [Three to five essential features]
- Business goal: [Conversion, activation, retention, or another metric]
- Technology stack: [Framework, styling, data, and hosting]
- Brand tone: [Voice and visual character]

Required design and implementation criteria:
1. Make the relationships and states of devices, rooms, and automations understandable at a glance.
2. Provide prevention, explanation, and recovery paths for real-time status, permissions, and offline states.
3. Specify loading, empty, error, success, disabled, permission-denied, and partial-data states.
4. Preserve content priority and navigation at 360px, 768px, and 1280px.
5. Use semantic HTML, logical keyboard order, visible focus, 44px touch targets, and WCAG AA contrast.
6. Define page structure, components, data, actions, microcopy, edge cases, and measurable acceptance criteria.
7. Give every indexable page a unique title, meta description, canonical URL, heading hierarchy, and crawlable internal links.
8. Answer important user questions directly in visible content. Keep WebSite, WebPage, BreadcrumbList, and CreativeWork structured data consistent with that content.
9. Set performance budgets for the main image, fonts, JavaScript, Core Web Vitals, and slow-network behavior.
10. Return a testable result rather than general design advice.

Output in this order:
- Goals, assumptions, and success metrics
- User flow and information architecture
- Screen and component specification
- Data model, states, and error recovery
- Responsive and accessibility rules
- SEO, AEO, and structured-data plan
- Implementation plan or code
- Verifiable completion checklist

These tokens are a starting point, not a request to clone Home Assistant. Validate contrast, hierarchy, density, and brand distinctiveness for your own users.

Expected deliverables

• Product requirements tied to user outcomes and measurable success criteria
• Information architecture and the critical end-to-end flow
• Component contracts covering data, states, actions, and accessibility
• Mobile, tablet, and desktop adaptation rules
• SEO/AEO content model, structured data, and internal-link plan
• Performance budgets, analytics events, tests, and release acceptance criteria

Follow-up prompts

1. "Take the most important flow and define normal, loading, empty, partial-data, validation-error, server-error, permission-denied, and success states with one consistent data model."
2. "Convert the specification into semantic, reusable components with realistic English content at 360px, 768px, and 1280px. Include keyboard and screen-reader behavior."
3. "Audit the result for real-time status, permissions, and offline states. Rank failures by severity and give observable evidence, a fix, a verification method, and a completion condition."
4. "Remove anything that resembles Home Assistant's brand or proprietary layout while preserving only the useful information-architecture principle."
5. "Split the result into engineering tickets with purpose, data requirements, component API, edge cases, accessibility criteria, tests, and dependencies."

Validation checklist

• ☐ Home Assistant is used only as an information-architecture reference.
• ☐ Project-specific users, problems, features, and metrics replace every placeholder.
• ☐ The priority and state changes of devices, rooms, and automations are explicit.
• ☐ Trust and recovery paths address real-time status, permissions, and offline states.
• ☐ Empty, delayed, partial, failed, and permission-restricted states are covered.
• ☐ Keyboard, screen reader, 200% zoom, reduced motion, and contrast can be tested.
• ☐ The final design has its own product language and visual identity.
