HA NOVA History

Scope

Read-only timeline work:

entity state history over a bounded time range
logbook queries over a bounded time range
long-term statistics over a bounded time range
concise "what happened?" summaries

Not in scope:

live subscriptions
system logs
trace debugging
calendar queries (use ha-nova:calendar)
giant raw exports

Use ha-nova:diagnose for traces (it owns trace analysis; ha-nova:read only surfaces raw trace data when the user explicitly asks for it with no failure question attached), ha-nova:calendar for calendars, and ha-nova:fallback for subscriptions.

Bootstrap (once per session)

Read and follow ../ha-nova/session-bootstrap.md. Verify relay CLI: ha-nova relay health If this fails: ha-nova setup

Relay Contract

Use file-based relay requests:

ha-nova relay core --method GET --path <history-path> --out <result-file>
ha-nova relay core --method GET --path <logbook-path> --out <result-file>
ha-nova relay ws --data-file <payload-file> --out <result-file>
ha-nova relay jq --file <result-file> --jq-file <filter-file>

For ha-nova relay jq, the filter is positional unless --jq-file is used. Do not invent a --jq flag.

Canonical paths:

/api/history/period/<start>?filter_entity_id=<entity_id>&end_time=<end>
/api/logbook/<start>?entity=<entity_id>&end_time=<end> — entity takes a comma-separated LIST for several entities (verified on 2026.8.0: the endpoint splits on commas and ignores unknown ids), and omitting it entirely returns the whole home for that window. filter_entity_id belongs to the HISTORY endpoint; using it here silently returns everything.
recorder/statistics_during_period

Prefer minimal_response and no_attributes on large history queries when the task only needs state transitions. Envelope parsing follows skills/ha-nova/relay-api.md → Standard Envelope; relay-core response shape here stays under .data.body.

history series: .data.body[0]
logbook entries: .data.body
do not probe .[0] or .[0][0] against the relay envelope Recorder statistics response stays under WS .data.

Statistics semantics (recorder/statistics_during_period) — check which keys the response actually carries before summarizing:

Measurement stats (temperature, humidity) carry mean/min/max. Metered total_increasing stats (energy, water, gas) are consumption: request change in the types list and SUM the per-bucket change values over the window (the pattern skills/energy/energy-reference.md uses) — never an average, and never last sum − first sum, which drops the first bucket's consumption and reads 0 for a single bucket.
Long-term statistics carry their own unit, which can differ from the entity's current unit after a unit change (the exact trap ha-nova:maintenance repairs) — report the unit from the statistics metadata, and flag a mismatch instead of mixing units.
statistic_id is not always an entity_id: external statistics use domain:object_id (colon) and have no entity — resolve via recorder/list_statistic_ids when unsure.
Daily/monthly buckets follow the HA server's local timezone including DST shifts — a "day" is not a fixed 24 h; name the bucket timezone when precision matters.
The queried window is what was REQUESTED, not what was observed: report the actual first-to-last sample span and material gaps alongside the requested window, and never phrase a result as covering "the last N days" when the evidence spans less (skills/ha-nova/write-safety.md → Time-Window Evidence — applies to raw history summaries too). For recorder/statistics_during_period the response carries aggregated period BUCKETS, not sample timestamps: report the first-to-last bucket span and NAME it as bucket coverage — sample density claims come only from raw state history, never from LTS buckets.

Flow

Resolve the exact entity target when needed.
Set a bounded window.
- if the user gave a range, use it
- otherwise default to the last 24 hours for history/logbook
- otherwise default to the last 30 days for statistics/trend questions
- if the requested window is too broad, narrow it before querying
Choose the source:
- history for state transitions and values
- logbook for human-readable events and automation activity
- statistics for multi-day trends, comparisons, or long-term summaries
Execute the read into <result-file>.
Summarize first:
- key transitions
- first/last seen values
- notable gaps or bursts
- key periods or trend direction for statistics
- if the raw state series can contain unknown or unavailable, do not run numeric min/max across the whole series unless you first filter to numeric states safely
- prefer simple reductions that do not depend on fragile timestamp parsing unless the user explicitly asked for gap analysis
- for the default summary, do not build complex jq expressions just to recover min/max event timestamps; numeric range plus a few direct sample timestamps is enough
Only show raw excerpts if the user explicitly asks.

Output Format

Apply skills/ha-nova/output-rules.md to all user-facing output.

Target
Window
Summary
Key events, Key transitions, or Key periods
Next step

These slots render the Report shape (output-rules.md). Keep default output compact. Raw payload dumps are opt-in only.

Safety

Read-only skill: never issue mutating relay or service calls.
For write intent, hand off to the owning skill; unfamiliar writes go through ha-nova:fallback first.
Read-only skill. No writes.
No guessed entity ids.
If more than one entity could match, ask one blocking question.
If the data is incomplete for the requested conclusion, say so explicitly.

Whole-home and multi-entity windows: omitting entity from the logbook path returns everything that happened ("what happened overnight?") — allowed for windows up to 24 hours, summary-first, never a raw dump. For a small explicit set, pass the ids as a comma-separated entity value on that LOGBOOK path — verified against 2026.8.0: the endpoint splits on commas, and an unknown id in the list is ignored rather than failing the query. filter_entity_id belongs to the history endpoint, and using it here silently returns the whole home instead. That is how you compare two people's arrival times in one call.

Guardrails

Never run an unbounded history/logbook/statistics query.
Cap default history/logbook windows at 24 hours unless the user asked for more; statistics/trend questions keep the Flow's 30-day default.
If the user asks for a very large export, narrow the request first.
Prefer a short summary over dumping a long raw timeline.

# HA NOVA History

## Scope

Read-only timeline work:
- entity state history over a bounded time range
- logbook queries over a bounded time range
- long-term statistics over a bounded time range
- concise "what happened?" summaries

Not in scope:
- live subscriptions
- system logs
- trace debugging
- calendar queries (use `ha-nova:calendar`)
- giant raw exports

Use `ha-nova:diagnose` for traces (it owns trace analysis; `ha-nova:read` only surfaces raw trace data when the user explicitly asks for it with no failure question attached), `ha-nova:calendar` for calendars, and `ha-nova:fallback` for subscriptions.

## Bootstrap (once per session)

Read and follow `../ha-nova/session-bootstrap.md`.
Verify relay CLI: `ha-nova relay health`
If this fails: `ha-nova setup`

## Relay Contract

Use file-based relay requests:
- `ha-nova relay core --method GET --path <history-path> --out <result-file>`
- `ha-nova relay core --method GET --path <logbook-path> --out <result-file>`
- `ha-nova relay ws --data-file <payload-file> --out <result-file>`
- `ha-nova relay jq --file <result-file> --jq-file <filter-file>`

For `ha-nova relay jq`, the filter is positional unless `--jq-file` is used. Do not invent a `--jq` flag.

Canonical paths:
- `/api/history/period/<start>?filter_entity_id=<entity_id>&end_time=<end>`
- `/api/logbook/<start>?entity=<entity_id>&end_time=<end>` — `entity` takes a
comma-separated LIST for several entities (verified on 2026.8.0: the endpoint
splits on commas and ignores unknown ids), and omitting it entirely returns
the whole home for that window. `filter_entity_id` belongs to the HISTORY
endpoint; using it here silently returns everything.
- `recorder/statistics_during_period`

Prefer `minimal_response` and `no_attributes` on large history queries when the task only needs state transitions.
Envelope parsing follows `skills/ha-nova/relay-api.md` → Standard Envelope; relay-core response shape here stays under `.data.body`.
- history series: `.data.body[0]`
- logbook entries: `.data.body`
- do not probe `.[0]` or `.[0][0]` against the relay envelope
Recorder statistics response stays under WS `.data`.

Statistics semantics (`recorder/statistics_during_period`) — check which keys the response actually carries before summarizing:
- Measurement stats (temperature, humidity) carry `mean`/`min`/`max`. Metered `total_increasing` stats (energy, water, gas) are consumption: request `change` in the `types` list and SUM the per-bucket `change` values over the window (the pattern `skills/energy/energy-reference.md` uses) — never an average, and never `last sum − first sum`, which drops the first bucket's consumption and reads 0 for a single bucket.
- Long-term statistics carry their own unit, which can differ from the entity's current unit after a unit change (the exact trap `ha-nova:maintenance` repairs) — report the unit from the statistics metadata, and flag a mismatch instead of mixing units.
- `statistic_id` is not always an `entity_id`: external statistics use `domain:object_id` (colon) and have no entity — resolve via `recorder/list_statistic_ids` when unsure.
