A communication device in one aspect of the present disclosure includes a storage, a first wireless communication circuit, an information obtaining circuit, and a storing processing circuit. The first wireless communication circuit receives first information through an antenna. The first information is wirelessly transmitted from a first transmission device. The first information corresponds to the first transmission device. The first transmission device is configured to be connected to an electric work machine or is connected to the electric work machine. The information obtaining circuit obtains the first information through the first wireless communication circuit in response to a first event being occurred or having occurred. The storing processing circuit stores the first information from the information obtaining circuit into a storage.

A system, method, and apparatus for controlling a plurality of devices are provided. The system includes a remote control device comprising a processor configured to generate a carousel zone comprising at least a subset of graphical icons of a plurality of graphical icons, determine a first target device and a second target device from the plurality of devices, generate a first user interface based on the first target device, the first user interface associated with a first set of commands, in response to a user input, generate a second user interface based on the second target device, the second user interface associated with a second set of commands, control the first target device based on the first set of commands, and control the second target device based on the second set of commands.

A password less login using a smart device is caused to retrieve from a cloud-server a one-time use code. The smart device is associated with a virtual user account to control a plurality of controllable devices with a device app installed on a smart device. The one-time use code is provided to a controllable device and the controllable device is caused to provide the one-time use code back to the smart device. The app causes the one-time use code provided back to the smart device by the controllable device to be authenticated. In response to the one-time use code being authenticated, the controllable device is bound to the app whereupon the controllable device is controllable through use of the app.

An equipment control method, applied to a mobile terminal, includes: positioning, in response to the mobile terminal pointing to equipment to be controlled in which an external ultra-wideband positioning device is installed, the external ultra-wideband positioning device, the external ultra-wideband positioning device having a binding relationship with the equipment to be controlled; determining the equipment to be controlled that is bound to the external ultra-wideband positioning device based on the binding relationship, in response to positioning to the external ultra-wideband positioning device; and retrieving and displaying a control interface of the equipment to be controlled that matches the equipment to be controlled. When the terminal points to the equipment to be controlled, it can automatically select and control the equipment to be controlled in which an external ultra-wideband positioning device is installed, such that the equipment that originally had no ultra-wideband positioning control can be controlled automatically and intelligently.

A method includes identifying a plurality of vehicles within a geographic area; transmitting a first signal to a device of a customer, the first signal being configured to control each of the plurality of vehicles; receiving a selection of a vehicle from among the plurality of vehicles; and transmitting a second signal to the device in response to receiving the selection, the second signal modifying the first signal to be disabled from controlling the plurality of vehicles except the selected vehicle.

A load control system may include control devices for controlling electrical loads. The control devices may include load control devices, such as a lighting device for controlling an amount of power provided to a lighting load, and controller devices, such as a remote control device configured to transmit digital messages for controlling the lighting load via the load control device. The remote control device may communicate with the lighting devices via a hub device. The remote control device may detect a user interface event, such as a button press or a rotation of the remote control device. The remote control device or the hub device may determine whether to transmit digital messages as unicast messages or multicast messages based on the type of user interface event detected. The remote control device, or other master device, may synchronize and/or toggle an on/off state of lighting devices in the load control system.

In response to a detected presence of an intended target appliance within a logical topography of controllable appliances identity information associated with the intended target appliance is used to automatically add to a graphical user interface of a controlling device an icon representative of the intended target appliance and to create at a Universal Control Engine a listing of communication methods for use in controlling corresponding functional operations of the intended target appliance. When the icon is later activated, the controlling device is placed into an operating state appropriate for controlling functional operations of the intended target appliance while the Universal Control Engine uses at least one of the communication methods to transmit at least one command to place the intended target appliance into a predetermined operating state.

Disclosed is a method for controlling a command input device. The method includes: sensing contact between a home appliance and the command input device; based on sensing the contact between the home appliance and the command input device, determining the home appliance as a target home appliance to be controlled by the command input device; and based on the determination of the home appliance as the target home appliance to be controlled by the command input device, activating a remote controller provided by the command input device and configured to control the target home appliance.

A load control system may include devices for performing communications for controlling an amount of power provided to an electrical load. The devices may include load control devices that may communicate by transmitting digital messages. A user device having an adjustable wireless communication range may be used for discovering devices, configuring devices, and/or diagnosing devices in the load control system. The user device may detect whether devices are within an established wireless communication range of one another for performing communications. The user device may detect digital messages transmitted from a device and/or digital messages received at a device to determine whether the digital messages are correctly communicated in the load control system. The user device may provide an indication to a user indicating whether a digital message is correctly transmitted or received by a device in the load control system.
