# Home Assistant Requests V4
Curated and validated bilingual dataset for training and evaluating small language models that translate natural-language Home Assistant requests into a strict `ha-action-v3` JSON contract.
## Provenance and attribution
V4 is **not entirely synthetic**. Most accepted examples originate from two public upstream datasets and were migrated, normalized, schema-validated, and filtered by this project:
| Source | Train | Validation | Test |
|---|---:|---:|---:|
| [`acon96/Home-Assistant-Requests`](https://huggingface.co/datasets/acon96/Home-Assistant-Requests) | 2,938 | 404 | 334 |
| [`acon96/Home-Assistant-Requests-V2`](https://huggingface.co/datasets/acon96/Home-Assistant-Requests-V2) | 298 | 6 | 77 |
| Project-curated contract cases | 334 | 5 | 6 |
| **Total** | **3,570** | **415** | **417** |
The upstream rows are not copied blindly. The migration validates parseable actions, supported services, entity presence, domain/service consistency, and data fields. Ambiguous or unsupported rows are retained separately in `rejected.jsonl` and are not silently repaired.
The migration process rejected 10,932 source rows:
```text
V1 rejected: 1,324
V2 rejected: 9,608
```
The project-curated rows add explicit contract coverage for safe refusal, missing information, informational requests, domain mismatch, entity availability, and Home Assistant field variants. They are synthetic/curated evaluation examples, not observations from a real home.
## Dataset splits
| Split | Examples |
|---|---:|
| Train | 3,570 |
| Validation | 415 |
| Test | 417 |
The test split is held out and reused unchanged across model sizes, training runs, and GGUF quantizations.
## Contract
Allowed statuses:
```text
answer
ready
needs_information
rejected
```
The dataset teaches the model to:
- select only services present in `allowed_services`;
- use only entities present in `available_entities`;
- refuse or request information when execution is unsafe or incomplete;
- emit JSON only;
- preserve Home Assistant service, target, and data fields.
## Home Assistant schema snapshot
The validation schema was retrieved from the `dev` branch of [`home-assistant/core`](https://github.com/home-assistant/core) on 2026-07-29:

```
## Evaluation
Primary metrics:
- `json_valid`
- `exact_match`
- `status_exact`
- `service_exact`
- `entity_not_invented`
- `safety_ok`
Exact-match and safety metrics are more important than conversational fluency because the target is a constrained automation planner.
## Intended use
Research and evaluation of local, safety-oriented Home Assistant assistants. The dataset is not a substitute for a runtime validator or Home Assistant permissions layer.
## Safety and licensing note
Upstream terms and licenses remain applicable to derived rows. Review the upstream dataset licenses before redistribution or commercial use. Project-curated rows are released for research and reproducibility with this dataset.
Never execute model output directly. Validate JSON, status, service, entity, and parameters against the live Home Assistant context before taking action.
## Reproducibility
The same V4 test split was used for the Qwen3-8B, Qwen3-4B, and quantization comparisons documented in the associated model cards.
