Description

Hub device and in-house device control system using the same

Embodiments of the present invention relate to in-house remote control technology.

Recently, as interest in the Internet of Things (IoT) increases, the number of cases in which IoT is applied to various fields is increasing. In particular, various attempts are being made to control home appliances, such as home or office, from a remote location with an increase in demand for smart homes. In order to remotely control a home appliance, such as a home or office, a hub for relaying a remote control terminal and a home appliance, such as a home or office, is required.
