wherein the basic information about the IoT device is included in an onboarding payload, and

wherein the onboarding payload includes at least one of a vendor ID element designating a vendor ID for the IoT device or a product ID element designating a product ID for the IoT device.

6 . The method of claim 2 , wherein the first discovery method is a domain name service (DNS)-service discovery (SD) discovery method.

7 . The method of claim 2 , wherein the temporal network connection information is generated by the electronic device for the IoT device.

8 . The method of claim 2 , further comprising, in case that the discovered IoT device is registered with the IoT service, deleting the temporal network connection information.

9 . The method of claim 1 , wherein the auxiliary device communicates with the IoT device using a near field communication (NFC) method.

10 . The method of claim 1 , wherein the electronic device is a TV, the auxiliary device is a remote controller (RC) supporting an NFC communication function, and the IoT device is an electronic device supporting an active tag.

11 . An electronic device for connecting an Internet of things (IoT) device to an IoT service using an auxiliary device, the electronic device comprising:

a transceiver;

memory, comprising one or more storage media, storing instructions; and

one or more processors communicatively coupled to the transceiver and the memory,

wherein the instructions, when executed by the one or more processors individually or collectively, cause the electronic device to:

receive, from the IoT device, basic information about the IoT device through the auxiliary device;

discover the IoT device using one of at least one discovery method based on the basic information; and

register the discovered IoT device with the IoT service,

wherein the auxiliary device supports a communication function with the electronic device and the IoT device, and

wherein the basic information about the IoT device includes access point (AP) pre-connection capability information indicating whether the IoT device supports an AP pre-connection function.

12 . The electronic device of claim 11 , wherein the instructions, when executed by the one or more processors individually or collectively, further cause the electronic device to:

transmit, to the IoT device, temporal network connection information or network connection information for network connection through the auxiliary device; and

discover the IoT device pre-connected to a network using the temporal network connection information or the network connection information, using a first discovery method among the at least one discovery method.

13 . The electronic device of claim 12 ,

wherein the basic information about the IoT device is included in an onboarding payload, and

wherein the onboarding payload includes at least one of a vendor ID element designating a vendor ID for the IoT device or a product ID element designating a product ID for the IoT device.

14 . The electronic device of claim 12 , wherein the first discovery method is a domain name service (DNS)-service discovery (SD) discovery method.

15 . The electronic device of claim 12 , wherein the temporal network connection information is generated by the electronic device for the IoT device.
