Adding the sensor to Home Assistant

Sensor can be added to HS3's Home Assistant within the ESPHome in Home Assistant dashboard. The .yaml configuration file should point to the project template within this repository:

packages:
  esphome.project-template: github://hs3city/kingbob-plant-sensor/LILYGO-T-Higrow-ESP32.yaml@main

Calibration

To get accurate readings the sensor should be calibrated before first use. Calibration process is described in the official LILYGO-T-Higrow-Esphome website.

You can utilize the branch calibration in this repository, which contains all changes in .yaml file required for the calibration process:

packages:
  esphome.project-template: github://hs3city/kingbob-plant-sensor/LILYGO-T-Higrow-ESP32.yaml@calibration
