What's in it

Data offered llm-inferred: soil moisture sensor readings (per zone) · weather forecast · past 24h precipitation (Open-Meteo, 72h window) · Home Assistant valve and watering history · per-zone watering decision (MINUTES: 0–25)
Coverage llm-inferred: Global
Update frequency docs-verified: Per dusk and dawn run (sunrise/sunset trigger), plus manual runs
Formats llm-inferred: YAML (HA blueprint, script and package) · HACS integration
Access docs-verified: Open-source under MIT licence. Requires Home Assistant 2024.6.0+, HACS, and an LLM endpoint (AO Reach on :8765 with token appId agentic-watering, or a legacy OpenAI-compatible chat-completions URL). Irrigation valves must expose start/stop watering services.

Useful for

Use cases llm-inferred: Pilot sensor-driven, per-zone irrigation control for a landscape or planted green-space site before wider rollout · Test LLM irrigation decision logic in simulate mode and with short manual runs before unattended operation · Prototype soil-moisture and forecast-driven watering rules for establishment planting on client sites
Audience llm-inferred: smart-home integrators · landscape and irrigation contractors · environmental monitoring technicians

Limitations

Constraints llm-inferred: Controls real irrigation valves; docs require simulate mode or a short manual run before unattended use · Needs a working LLM endpoint: AO Reach (requires AGENTIC_SERVE_SESSION_OVERLAY=1 and AGENTIC_SERVE_MCP_TUNNEL=1) or a legacy chat-completions URL · weather-mcp tunnel needs Node.js/npx on the Home Assistant host · Only works with irrigation integrations exposing start/stop watering services · Home Automation tool, not a UK water, civils or environmental dataset or data API; no UK data sources documented
