MQTT Binary Sensor - Bluetooth LE Device Tracker - Home Assistant

A simple example describing how to track a Bluetooth Low Energy device with an ESP32, the MQTT protocol and Home Assistant. Please note that the targeted device can't have a changing BLE address (normally called random instead of public address).

Configuration

To configure this sketch, you have to rename the header file example.config.h in config.h, provide the Bluetooth device(s) to track and add your Wi-Fi and MQTT credentials in the SOFTWARE SECTION.

Bluetooth Device(s)

#define NB_OF_BLE_TRACKED_DEVICES 1
BLETrackedDevice BLETrackedDevices[NB_OF_BLE_TRACKED_DEVICES] = {
  {"11:22:33:44:55:66", false, 0, false, {0}}
};

// Location of the BLE scanner
#define LOCATION "bedroom"

or with multiple devices

#define NB_OF_BLE_TRACKED_DEVICES 3
BLETrackedDevice BLETrackedDevices[NB_OF_BLE_TRACKED_DEVICES] = {
  {"11:22:33:44:55:66", false, 0, false, {0}},
  {"11:22:33:44:55:66", false, 0, false, {0}},
  {"11:22:33:44:55:66", false, 0, false, {0}}
};

// Location of the BLE scanner
#define LOCATION "bedroom"

Credentials

// Wi-Fi credentials
#define WIFI_SSID     ""
#define WIFI_PASSWORD ""

// MQTT
#define MQTT_USERNAME     ""
#define MQTT_PASSWORD     ""
#define MQTT_SERVER       ""
#define MQTT_SERVER_PORT  1883

Home Assistant

To add the occupancy sensor to Home Assistant, please edit and add this snippet into your configuration. Make sure to replace <CHIP_ID, <LOCATION> and <BLE_ADDRESS> with the values defined in config.h.

# Example configuration.yaml entry
binary_sensor:
  - platform: mqtt
    name: 'Occupancy'
    state_topic: '<CHIP_ID>/sensor/<LOCATION>/<BLE_ADDRESS>/state'
    availability_topic: '<CHIP_ID/availability'
    device_class: occupancy
