// BresserWeatherSensorMQTTWifiMgr.ino
//
// Example for BresserWeatherSensorReceiver -
// this is finally a useful application.
//
// At startup, first a WiFi connection and then a connection to the MQTT broker is established.
// (Edit secrets.h accordingly!)
//
// Then receiving data of all sensors (as defined in NUM_SENSORS, see WeatherSensorCfg.h)
// is tried periodically.
// If successful, sensor data is published as MQTT messages, one message per sensor.
// If the sensor ID can be mapped to a name (edit sensor_map[]), this name is used as the
// MQTT topic, otherwise the ID is used.
// From the sensor data, some additional data is calculated and published with the 'extra' topic.
//
// Furthermore, Home Assistant auto-discovery messages are published at an interval of
// DISCOVERY_INTERVAL.
//
// The data topics are published at an interval of >DATA_INTERVAL.
// The 'status' and the 'radio' topics are published at an interval of STATUS_INTERVAL.
//
// If sleep mode is enabled (SLEEP_EN), the device goes into deep sleep mode after data has
// been published. If AWAKE_TIMEOUT is reached before data has been published, deep sleep is
// entered, too. After SLEEP_INTERVAL, the controller is restarted.
//

//
// History:
//
// 20230619 Created from BresserWeatherSensorMQTT
// 20230708 Changed MQTT payload and topic from char[] to String
// 20230709 Added lightning sensor
// 20230710 Added optional JSON output of floating point values as strings
// Modified MQTT topics
// 20230711 Changed remaining MQTT topics from char[] to String
// Fixed secure WiFi with CHECK_CA_ROOT for ESP32
// Added define RX_STRATEGY
// 20230717 Added startup handling to rain gauge
// 20230817 Added rain gauge reset via MQTT
// 20230826 Added hourly (past 60 minutes) rainfall as 'rain_h'
// 20231030 Fixed and improved mapping of sensor IDs to names
// Refactored struct Sensor
// 20231103 Improved handling of time and date
// 20231110 Fixed false double reset detection on wake-up from deep sleep
// 20240113 Added lightning data post-processing
// 20240122 Added lightning post-processing reset
// 20240129 Replaced SPIFFS by LittleFS
// Added formatting of LittleFS partition if mounting failed
// 20240209 Added Leakage, Air Quality (HCHO/VOC) and CO2 Sensors
// 20240213 Added PM1.0 to Air Quality (Particulate Matter) Sensor decoder
// 20240503 Fixed setting of RTC via SNTP in case on non-secure WiFi config
// 20240504 Added board initialization
// 20240507 Added configuration of maximum number of sensors at run time
// 20240603 Modified for arduino-esp32 v3.0.0
// 20241113 Added getting/setting of sensor include/exclude lists via MQTT
// 20250127 Added Globe Thermometer Temperature (8-in-1 Weather Sensor)
// 20250129 Added calculated WBGT (Wet Bulb Globe Temperature)
// 20250220 Added Home Assistant auto discovery
// 20250223 Moved MQTT functions to src/mqtt_comm.h/.cpp
//
// ToDo:
//
// -
//
// Notes:
//
// - To enable wakeup from deep sleep on ESP8266, GPIO16 (D0) must be connected to RST!
// Add a jumper to remove this connection for programming!
// - MQTT code based on https://github.com/256dpi/arduino-mqtt
// - For secure MQTT (TLS server verifycation, check the following examples:
// - ESP32:
// https://github.com/espressif/arduino-esp32/blob/master/libraries/WiFiClientSecure/examples/WiFiClientSecure/WiFiClientSecure.ino
// - ESP8266:
// https://github.com/esp8266/Arduino/blob/master/libraries/ESP8266WiFi/examples/BearSSL_Validation/BearSSL_Validation.ino
// - WiFiManager code based on example AutoConnectwithFSParameters
// - Using ESP_DoubleResetDetector (https://github.com/khoih-prog/ESP_DoubleResetDetector)
// to force WiFiManager reconfiguration
