ESP32 Communicating With Xiaomi Flora Plant Sensor Using BLE

Using ESP32 to communicate with Xiaomi flora (miflora) plant sensor using BLE and posting the values on MQTT server. I also demonstrate the use of Home Assistant miflora sensor component. Change ESP32 Partition: Home Assistant miflora sensor: GitHub: sidddy/flora Archived code from below config.h // array of different xiaomi flora MAC addresses char* FLORA_DEVICES[] = { "C4:7C:8D:67:11:11", "C4:7C:8D:67:22:22", "C4:7C:8D:67:33:33" }; // sleep between to runs in seconds #define SLEEP_DURATION 30 * 60 // emergency hibernate countdown in seconds #define EMERGENCY_HIBERNATE 3 * 60 // how often should the battery be read - in run count #define BATTERY_INTERVAL 6 // how often should a device be retried in a run when something fails #define RETRY 3 const char* WIFI_SSID = "ssid"; const char* WIFI_PASSWORD = "password"; // MQTT topic gets defined by "<MQTT_BASE_TOPIC>/<MAC_ADDRESS>/<property>" // where MAC_ADDRESS is one of the values from FLORA_DEVICES array // property is either temperature, moisture, conductivity, light or battery const char* MQTT_HOST = "10....
