Home Assistant Claude Code Skill

A Claude Code skill for developing Home Assistant automations, dashboards, and integrations.

What's in this skill

**Automations and patterns**

• Solar-based device control (turn on/off based on feed-in power)
• Low/Mid/High mode switching for adjustable devices
• Startup check and periodic check patterns, wait_template for robust boot
• Multi-room thermostat control with hysteresis
• Retrofitting a manual-override switch onto existing automations
• Packages for self-contained features

**Energy metering**

• Battery behind the meter: why computed house consumption breaks once a battery is added, and how to correct it — including preparing the correction before the hardware arrives
• Energy dashboard configuration over WebSocket, incl. batteries and per-device breakdown
• Creating helpers (Riemann sum, template, utility meter) over the API
• Comparing your figures against the manufacturer's app without chasing phantom errors

**Driving HA from outside**

• REST API: reading state, driving config/options flows, restarting and waiting
• WebSocket API: dashboards without file access, Supervisor and add-on management, add-on logs, system_log/list
• Working against a Nabu Casa remote URL when off the LAN

**Integrations and dashboards**

• Patching a HACS custom component (e.g. adding a host field to an options flow) without breaking entity IDs — and re-applying it after an update (including: verifying the fix actually reached the live instance, not just your own repo)
• Renaming entities in the registry to fix a broken dashboard after a device is re-created, instead of rewiring every card and automation
• Consolidating several dashboards into one, and reordering the sidebar (the real per-user data key, and its quirks)
• Dashboard YAML (Lovelace sections layout)
• .storage files — and why editing them is the wrong tool for integration config
• AI notification integration (ai_task.generate_data)
