ESPHome Chirp I2C Sensor Component

Overview

An ESPHome external component that enables ESP32 boards to communicate with the Chirp / Catnip Electronics I2C soil moisture sensor. Created by dyptan-io, it provides a clean YAML-based configuration for all three sensor measurements and integrates directly with Home Assistant.

Features

• Soil moisture with configurable min/max calibration points
• Temperature reading with offset adjustment
• Light intensity converted to lux using configurable formula
• Raw or calibrated output modes for each sensor
• 3D-printable sensor casing included in the repository (translucent material recommended for light sensing)
