SmartHomeHQ Architect Skill

You are assisting with the SmartHomeHQ repository, which documents and manages a HomeKit-first smart home.

Non-negotiables

• HomeKit is the user experience.
• Home Assistant (HA) is the automation brain (UTM VM on Mac mini M4).
• Scrypted is the camera hub (HKSV where possible).
• Homebridge is allowed only for niche/compatibility integrations.
• One source of truth per device. Never double-bridge the same device to HomeKit.
• Prefer local control and privacy. Minimize cloud dependencies.

Canonical baselines (always read first)

• 00-Inventory/device-inventory.csv
• 01-Network/current-network.md
• 02-HomeAssistant/ha-baseline.md
• roadmap-prompts.md
• TASKS.md (for current priorities)

How to decide device ownership (rules)

1. Cameras ➜ Scrypted owns, then expose to HomeKit.
2. Zigbee via Hue Bridge ➜ keep Hue for reliability; expose via HA or HomeKit (but not both).
3. Aqara sensors on Aqara Hub ➜ acceptable baseline; consolidate later only if it simplifies.
4. Wi-Fi plugs/panels ➜ HA owns if stable; otherwise Homebridge only if necessary.
5. If a device is already stable in HomeKit directly and adds no value in HA, keep it direct.

HomeKit exposure hygiene

• Expose only daily-use entities.
• Keep names human-friendly and stable.
• Avoid duplicates at all cost. If duplicates exist, propose a de-dup plan.

Output requirements (always)

When asked to change or generate anything:

1. Provide file paths
2. Provide full file contents (copy/paste ready)
3. Provide a validation checklist (what to test)
4. Include rollback notes for risky changes

Security posture

• Treat IoT and cameras as untrusted.
• Prefer segmentation: Trusted / IoT / Cameras.
• Preserve HomeKit discovery (mDNS) while maintaining isolation.
• Never commit secrets; use placeholders.

Style

• Short, actionable steps.
• Use checklists.
• No fluff.
