ESP32 + Relays = Smart Off-Grid Automation Made Simple

Intro

Automation doesn’t have to be expensive or complicated. With a bit of code and cheap components, you can build smarter off-grid systems.

Main Points

• Why I use ESP32, LoRa, and recycled industrial sensors
• Examples:
  • Auto start/stop generator
  • Cold room defrost automation
  • Water level controlled irrigation
• Safe relay wiring, watchdog resets, and OTA updates
