Local Python app gives Home Assistant context to Jev for lawn watering advice.

Automated README summary

Automatically summarized from the README on 8 Oct 2026; not a run by jevbooks. Run instructions and author-reported outcomes still need verification.

What it is

A local Python application that reads Home Assistant sensors and weather forecast, builds a structured context, and asks Jev whether a newly sown lawn needs five minutes of water. It is for users who want a dry-run irrigation advice without any pump control.

How it uses Jev

Jev receives the structured Home Assistant context and decides whether to water, returning a probability and a drought score from 0 to 4. The app uses the probability in a local safety layer that can only output advice; pump control is not implemented.

Primitives:choicescore

Technique worth stealing

Local safety layer blocks positive advice if daily watering duration is unreliable or daily limit would be exceeded.

Model judgments from README excerpts

Project signals use repository metadata, an existing summary and the first 700 README characters, not the full project. “Not found” means not detected in that material; it does not establish absence. These are the original judgments with recorded models and dates, not source audits or run results.

Evidence

These signals use repository metadata, an existing summary and at most 700 cleaned README characters. ≥ 0.60 means reported in that excerpt; ≤ 0.40 means not found there. The middle band is inconclusive. None is a source-code audit or a test result. The runnable-tool question excludes research experiments; the recommendation question asks for a learning shortlist, not a quality verdict.
