## Overview

This repository implements local, scheduled plant irrigation on a Shelly Plus Uni: periodic sensing creates a watering job, and scheduled pump runs measure again, water in portions, and update learned pump effectiveness. Installation configures schedules and starting values; hardware checks and calibration support setup and tuning. The README documents these runtime capabilities, while sampled source mainly covers supporting tools and the mock, so links for core script behavior follow the documented workflow rather than inspected script internals.
