//     Demonstrates how to use SpanPoint() to implement   //
//     two remote temperature sensors on separate ESP32   //
//     devices.                                           //
//                                                        //
//     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.                                    //
