 This repository contains code to use the [Homie](https://homieiot.github.io/homie-esp8266/docs/develop-v3/quickstart/what-is-it/) framework and its IoT convention with a soil moisture sensor from [April Brothers](https://wiki.aprbrother.com/en/ESP_Soil_Moisture_Sensor.html) (Source and schematic: https://github.com/AprilBrother/esp-soil-moisture-sensor). When this firmware is running, the sensor will publish it's sensor readings in the homie [convention format](https://homieiot.github.io/specification/spec-core-v2_0_1/). Based on the work of ve2cuz - [Real Drouin](https://www.qsl.net/v/ve2cuz//garden/)
