description: Presence history & tracker-health report — current home/away state, reliability, recent arrival/departure transitions, and activity patterns for person/device_tracker entities. Use when the operator asks about presence history or when a presence-dependent automation (locks, alarm, vacuum, climate) misbehaves.

HA Presence Report

Steps

1. Call `GetDateTime` for the current time reference. Read the stored locale from `.claude-code-hermit/OPERATOR.md` under `## HA hermit` (fall back to English if absent).

2. Read `.claude-code-hermit/raw/snapshot-ha-normalized-latest.json`.

• If the file is missing or older than 24 hours, prepend a staleness warning to the output:

> "Context snapshot is stale — run `/claude-code-homeassistant-hermit:ha-refresh-context` for accurate data."

• Filter `entity_index` to keys starting with `person.` or `device_tracker.`. **If no matching keys exist, emit "no presence entities found — presence tracking isn't configured in this HA instance" and stop. Do not proceed to the history fetch.**
• From the matched entities derive:
• **Current state**: value of `state` field (home / away / unknown / unavailable) and `last_changed` → "since HH:MM" relative to now.
• **Reliability flags**: mark an entity unreliable if `state == "unavailable"` OR `last_changed` is more than 48 hours ago (stale tracker).

3. Run:

   ${CLAUDE_PLUGIN_ROOT}/bin/ha-agent-lab ha fetch-history \
     --window-days 7 \
     --entities "device_tracker.*" "person.*" \
     --include-transitions

This writes `.claude-code-hermit/raw/snapshot-ha-history-7d-latest.json`.

4. Read `snapshot-ha-history-7d-latest.json`. For each presence entity:

• **Recent transitions**: show the last 5 entries from `transitions` (ordered chronologically), formatted as `HH:MM DD-Mon — <state>`.
• **Home/away split**: derive from `state_durations` — what percentage of the window was "home" vs "away".
• **Typical activity windows**: bucket the `transitions` list by UTC hour, keyed on direction: transitions *to* `home` are arrivals, transitions *to* `away` are departures. Report the top 1–2 arrival hours and departure hours separately (e.g. "typically arrives around 18:00 UTC, leaves around 08:00 UTC"). With ≥7d of data and ≥5 total transitions, state the windows; below that threshold, say "insufficient data for pattern detection." (`hour_histogram` counts all events regardless of direction, so use it only as a fallback for entities whose states aren't home/away.)

5. Compose and print the inline report in the operator's locale:

   ## Presence Report — <date>

   ### Current State
   <per-entity: who is home/away/unknown, since when>

   ### Tracker Health
   <list unreliable entities with reason; "All trackers healthy." if none>

   ### Recent Transitions (last 7 days)
   <per-entity: last 5 home/away events with timestamp>

   ### Activity Patterns
   <per-person: typical arrival/departure windows, or "insufficient data">

6. Write `compiled/presence-report-<YYYY-MM-DD>.md` with frontmatter:

   title: "Presence Report — <YYYY-MM-DD>"
   type: presence-report
   created: <ISO 8601 with UTC offset>
   task: <T-... for the open record in this turn; omit this field otherwise>
   tags: [presence, ha]

Body: the inline report from step 5.

7. Inside an open record's turn, pipe `[[compiled/presence-report-<date>.md]]` into `.claude-code-hermit/bin/hermit-run task note .claude-code-hermit <id>`. Otherwise skip the note.

Failure modes

• **HA unreachable** (fetch-history exits non-zero): print "Presence history unavailable — HA unreachable. Current state from snapshot shown above." and stop after step 2. Do not write the compiled artifact.
• **No presence entities** (step 2 short-circuit): print the message and stop. This is not an error.
• **Snapshot stale/missing** (step 2): include the staleness warning but continue — current-state and reliability from the snapshot will be degraded or absent; history fetch may still work.
