What is esphome-plant-watering?

This ESPHome plant watering system automates watering up to six plants using an M5Stack AtomS3-Lite, PbHub v1.1 hub, and Unit Watering modules with built-in moisture probes and pumps. It reads soil moisture as raw values, calibrates them to percentages, and categorizes states like Dry, Wet, or Saturated, exposing sensors and pump switches directly to Home Assistant for time-based or threshold automations. Built in C++ with ESPHome YAML config, it defaults to single-pump operation for safety but supports simultaneous pumps with external power.

Why is it gaining traction?

The Makefile-driven workflow with uv sync handles ESPHome deps cleanly—no PlatformIO mess—letting you validate, compile, flash via USB, and tail logs in seconds. Calibration is straightforward: log raw dry/wet values, tweak thresholds, and integrate with HA automations like "water if below 35% at 7:30 AM." As a github water meter and water tracker, it beats generic ESPHome hacks with PbHub-specific support and pump timeouts.

Who should use this?

M5Stack tinkerers building esphome plant watering setups for indoor herbs or balcony flowers. Home Assistant users wanting plug-and-play plant care without soldering—perfect for water plants pflege routines or DIY water plants selber machen projects. Skip if you're not buying the exact Unit Watering modules.

Verdict

Grab it if you have the M5Stack hardware: solid docs, easy HA integration, and ready automations make it practical despite 19 stars and 1.0% credibility score. Still early—test calibration thoroughly before scaling to six plants.
