• Simple plug in module to support the EEPROM rainfall backup concept

Thomas found if the system cannot connect to WiFi for any reason, the controller will time out. Of course the WDT takes over and a hard RESET is executed and rainfall data is lost. The ESP32 loses rainfall data at that point.

• I didn’t want to write to the internal EEPROM as wear out will eventually happen (pretty far out, but it will happen)

    I work for a company that makes NVM’s and spent several years of my semiconductor career testing them

  • It was a bit of a lark project, but a fun distraction, LOL
