  • Read SOILCAP analog values, apply calibration
  • Drive MOSFET to open/close solenoid
  • Manage RTC schedule and sleep/wake for low power
  • Local logging to SD (or circular buffer)
  • Publish minimal state to ESP32 for telemetry or accept commands

ESP32 responsibilities​

  • Connect to Wi-Fi and publish telemetry (MQTT/HTTP)
  • Receive OTA updates and remote config
