esp_ble_tracker

Track the device according to the preset IRK by scanning the MAC address of the BLE device, and send status change notifications via MQTT

How to use

Burn the "get_irk" to the ESP32, use the phone's Bluetooth to pair with the ESP32, and print the IRK of the phone's Bluetooth in the console.

（If you have multiple devices, please repeat the above steps）
Modify the macro definition in the "tracker/TrackerI.ino".

eg:WiFiSSID,WiFiPWD,MQTT_SERVER,MQTT_USER,MQTT_PWD

Enter your device's IRK and username in the "tracker/TrackerI.ino"

uint8_t irk[][ESP_BT_OCTET16_LEN] = {
  //your irks
  //eg:
  //{0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00},
  //{0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00}
};

String users[] = {
  //users
  //eg:
  "Jack", 
  "LeeMing"
};

Compile and burn "tracker/TrackerI.ino" to ESP32 and power up

Subscribe to the MQTT topic "v1/trackeri/state" and you will receive status messages

eg:

{
    "Jacky": {
        "currentState": 1,
        "originalState": 1
    },
    "Danson": {
        "currentState": 1,
        "originalState": 1
    },
    "Neely": {
        "currentState": 1,
        "originalState": 1
    }
}

state code -1:Init

state code 0:Not Found

state code 1:Found

Integrated

Because the MQTT message queue is used, it can theoretically be integrated into all platforms that support MQTT

Home Assistant

sensor:
 - platform:  mqtt
   name:  "Danson"
   state_topic:  "v1/trackeri/state"
   value_template:  "{{value_json['danson']['currentState'] | replace('1','At home') | replace('0','Leave home')}}"
 - platform:  mqtt
   name:  "DansonII"
   state_topic:  "v1/trackeri/state"
   value_template:  "{{value_json['dansonII']['currentState'] | replace('1','At home') | replace('0','Leave home')}}"
 - platform:  mqtt
   name:  "Neely"
   state_topic:  "v1/trackeri/state"
   value_template:  "{{value_json['Neely']['currentState'] | replace('1','At home') | replace('0','Leave home')}}"
