// Dead simple firmware for Sonoff switches - just HTTP server, button handler and OTA. Suitable for HomeBridge integration
//
// Tested with ESP Arduino cores 2.3.0 and 2.4.2
//
// Using WiFiManager and OneButton libraries
//

//
// Flash with
// Generic ESP8266 module, Flash mode DIO, Flash size 1M (no or 64k SPIFFS), 80MHz CPU, 40MHz flash
