ha-config-fetch

name	ha-config-fetch
description	Fetch local Home Assistant config snapshots from ha-data/ via fetch-ha-data.sh, gated by a freshness check. Use when a request touches existing automations, scenes, scripts, configuration.yaml, or Core/Supervisor logs — none of which the MCP server exposes.

HA Config Fetch

When to use

• The request involves existing automations, scenes, scripts, configuration.yaml, or logs.
• The MCP server does not expose these — ha-data/ snapshots are the only source.

Freshness gate

Before reading any file from ha-data/, run:

find ha-data/ -name '*.yaml' -mmin +1440 -print -quit | grep -q . && echo STALE || echo FRESH

• STALE, missing, or debugging request → run ./fetch-ha-data.sh from this skill's folder.
• FRESH and not a debugging task → read directly, skip the fetch.

Debugging requests (troubleshooting, log analysis, error investigation) always re-fetch — logs and state change frequently.

If ha-data/ does not exist at all, treat it as stale.

Fetch step

Run from the repository root:

.github/skills/ha-config-fetch/fetch-ha-data.sh

Optional: override the config directory (default /config):

.github/skills/ha-config-fetch/fetch-ha-data.sh /custom/path

File map

After the script completes, read the file(s) you need:

• ha-data/automations.yaml — all automations
• ha-data/scenes.yaml — all scenes
• ha-data/scripts.yaml — all scripts
• ha-data/configuration.yaml — main configuration
• ha-data/customize.yaml — entity customizations
• ha-data/esphome/*.yaml — every ESPHome device YAML found under the ESPHome data dir (secrets.yaml is always skipped, never snapshotted)
• ha-data/zigbee2mqtt/configuration.yaml — Zigbee2MQTT main config
• ha-data/zigbee2mqtt/devices.yaml — Zigbee2MQTT device definitions
• ha-data/zigbee2mqtt/groups.yaml — Zigbee2MQTT groups
• ha-data/zigbee2mqtt/state.json — Zigbee2MQTT runtime state (not YAML; freshness gate does not cover it — debugging requests always re-fetch)
• ha-data/logs/core.log — latest HA Core container logs (debugging)
• ha-data/logs/supervisor.log — latest Supervisor container logs (debugging)

Rules

• Never modify or commit files inside ha-data/ — gitignored, local-only snapshots.
• Do not assume file contents — always check freshness first.
