Disclosed is a system and method for power line control of electrical fans. The system generates a sinusoidal wave using a crystal oscillator. Control information is added to the sinusoidal wave by routing the wave through a phase inversion circuit a predetermined intervals according to a protocol. The resulting control signal is sent on a power line. The control signal is received using a crystal filter, decoded and converted to executable instructions for controlling a fan motor.

The IoT device (100) also includes a first network interface connectable to an IoT coordinator device (200) over a first network using a first network protocol, and a second network interface configured to communicate over a second network via a second network protocol. The IoT device (100) is configured to act as a bridge between the first and second networks, allowing integration of various smart building management services (600). A smart building control system (300) comprises a plurality of the IoT devices (100).

Disclosed herein is a method of connection of home appliance to a network, a network-connection system for home appliances, and an apparatus related to a network-connection setting for home appliances. The network connection method of home appliance includes operations in which a terminal device receives an input of an authentication key of an access point (AP) apparatus and the terminal device or the AP apparatus verifies and authenticates the authentication key; a home appliance is set to be in a state of communicating with the terminal device; the home appliance is interconnected to the terminal device and the terminal device transmits an identification number and the certificated authentication key of the AP apparatus to the home appliance; and the home appliance is connected to the AP apparatus based on the identification number and the authentication key of the AP apparatus.

The invention relates to a system for detecting an input and controlling at least one downstream device, wherein the system comprises at least one sensor device and an evaluation and control device connected to the sensor device for signalling purposes, wherein the at least one sensor device detects an input signal which varies at least over time in the form of a movement, wherein the evaluation and control device evaluates at least the time profile of the detected input signal, wherein at least one evaluation condition is specified, and wherein the downstream device is activated when the at least one evaluation condition is met.

User switching for multi-user devices is provided. Each of multiple users of the multi-user device can have multiple external accounts that are each associated with one or more applications installed at the device. The user switching is provided such that each application installed at the device can be operated using user-specific data for the correct account of the correct user. The user switching is provided such that an app developer of an application for the multi-user device does not have to manage multiple data stores for multiple users.

A display device for controlling a home appliance by using voice recognition according to an embodiment of the present invention includes: a wireless communication unit configured to wirelessly communicate with the home appliance; and a control unit configured to receive a voice command, to obtain intention of the received voice command, to determine whether the obtained intention is a custom operation request for controlling a function specialized for the home appliance, to convert the voice command into a custom operation command for performing the specialized function when the intention is the custom operation request, and to transmit the converted custom operation command to the home appliance through the wireless communication unit.

Techniques for suggesting accessory devices controlled by an application executing on a mobile device are disclosed. A method includes measuring one or more sensor values using one or more sensors of a mobile device and the one or more sensor values are determined from one or more signals emitted by a first one or more accessory devices. An area of a physical space for the first one or more accessory devices can be determined based on the one or more sensor values. A second one or more accessory devices associated with the same area as the first one or more accessory devices can be suggested to a user.
