// HomeSpan: A HomeKit implementation for the ESP32 //
|
|
// ------------------------------------------------ //

// Demonstrates how to use SpanPoint() to implement //
|

// two remote temperature sensors on separate ESP32 //

// //
|

// This sketch is for the MAIN DEVICE that contains //
|
|
// all the usual HomeSpan logic, plus two instances //
|
|
// of SpanPoint to read temperatures from two other //
|
|
// remote devices. //
