Matter Bridge distinguishes the connected devices (CON-1570)

[MaplestoryAlen]

I currently have two devices connected through a bridge. Device A is EP3 (thermostat) and EP4 (fan), while device B is EP5 (thermostat) and EP5 (fan). At this point, I don't know how to distinguish that EP3 and EP4 are physical devices, while EP5 and EP6 are another physical device.

esp_err_t create_bridge_devices(esp_matter::endpoint_t *ep, uint32_t device_type_id, void *priv_data)
{
esp_err_t err = ESP_OK;

ESP_LOGI("bridge", "Endpoint ID: %d", *ep);
ESP_LOGI("bridge", "Device Type ID: %d", device_type_id);
switch (device_type_id) {
case ESP_MATTER_ON_OFF_LIGHT_DEVICE_TYPE_ID: {
    on_off_light::config_t on_off_light_conf;
    err = on_off_light::add(ep, &on_off_light_conf);
    break;
}
case ESP_MATTER_DIMMABLE_LIGHT_DEVICE_TYPE_ID: {
    dimmable_light::config_t dimmable_light_conf;
    err = dimmable_light::add(ep, &dimmable_light_conf);
    break;
}
case ESP_MATTER_COLOR_TEMPERATURE_LIGHT_DEVICE_TYPE_ID: {
    color_temperature_light::config_t color_temperature_light_conf;
    err = color_temperature_light::add(ep, &color_temperature_light_conf);
    break;
}
case ESP_MATTER_EXTENDED_COLOR_LIGHT_DEVICE_TYPE_ID: {
    extended_color_light::config_t extended_color_light_conf;
    err = extended_color_light::add(ep, &extended_color_light_conf);
    break;
}

    on_off_switch::config_t switch_config;
    err = on_off_switch::add(ep, &switch_config);
    break;
}
case ESP_MATTER_THERMOSTAT_DEVICE_TYPE_ID:
	{
      thermostat::config_t thermostat;
      err = thermostat::add(ep, &thermostat);
      break;  	  
	}
case ESP_MATTER_FAN_DEVICE_TYPE_ID:
	{
      fan::config_t fan;
      err = fan::add(ep, &fan);
      break;  	  
	}
case ESP_MATTER_HUMIDITY_SENSOR_DEVICE_TYPE_ID: 
	{
	   humidity_sensor::config_t humidity_sensor;
       err = humidity_sensor::add(ep, &humidity_sensor);
       break;  	
	}
case ESP_MATTER_ROOM_AIR_CONDITIONER_DEVICE_TYPE_ID:
	{
	   room_air_conditioner::config_t room_air_conditioner;
       err = room_air_conditioner::add(ep, &room_air_conditioner);
       break;  	
	}	   
default: {
    ESP_LOGE(TAG, "Unsupported bridged matter device type");
    return ESP_ERR_INVALID_ARG;
         }
}
return err;

}

void UpdateEspnowDevice(uint8_t addr,uint32_t get_device_type)
{

espnow_ctrl_bind_info_t bind_info = 
{
  .mac = {0x1a,0x2b,0x3c,0x4a,0x5b,addr},	
  .initiator_attribute = ESPNOW_ATTRIBUTE_BASE,
};
if(get_device_type == THERMOSTAT_DEVICE_TYPE)
{
   matter_device_type_id = ESP_MATTER_THERMOSTAT_DEVICE_TYPE_ID;
}
else if(get_device_type == FAN_DEVICE_TYPE)
{
   matter_device_type_id = ESP_MATTER_FAN_DEVICE_TYPE_ID;
}
espnow_bridge_match_bridged_switch(bind_info.mac, bind_info.initiator_attribute,matter_device_type_id); 

}

Please take a look at the picture below. How should I display these three devices at this time? These devices are not BLE mesh and Zigbee, they are just ordinary devices

You need to use the TAGLIST feature on the Descriptor cluster to differentiate them. You can add serial number or whatever to the taglist.
