// HomeSpan: A HomeKit implementation for the ESP32 //
|
||||
// ------------------------------------------------ //
|
||||
// //
|
||||
// This sketch is for a Remote Temperature Sensor to //
|
||||
// be used in conjunction with the "MainDevice.ino" //
|
||||
// sketch running on a separate ESP32 //
|
||||
// //
|
||||
// The purpose of these sketches is to demonstrate //
|
||||
// how to use SpanPoint() to communication between //
|
||||
// a remote ESP32 device that takes measurements from //
|
||||
// a sensor, and a separate "main" ESP32 device that //
|
||||
// is running the full HomeSpan code, and thus //
|
||||
// connects to HomeKit. //
|
||||
// //
|
||||
// This sketch implements an Adafruit ADT7410 I2C //
|
||||
// Temperature Sensor. If you don't have such a //
|
||||
// device, please use the sketch "RemoteDevice.ino" //
|
||||
// instead. That sketch SIMULATES a temperature //
|
||||
// sensor and therefore allows you to learn how //
|
||||
// SpanPoint() works even though the temperature data //
|
||||
// itself isn't real. //
