Problems solved by technology

Since unicast messages can be sent individually to each lighting device in the group, using unicast messages to control the lighting level of the lighting devices in the group can make each lighting device in the group turn on, off or adjust the lighting at different times. Lighting intensity, which can be distracting and undesirable

Embodiment Construction

[0021] Figure 1A and 1B An example of a load control system 100 that may implement one or more message types for communicating digital messages is depicted. like Figure 1A As shown, the load control system 100 may include various control devices, such as input devices and / or load control devices. The input device may send a digital message to the load control device to cause the load control device to control the amount of power supplied from the AC power source 102 to the electrical loads in the load control system 100 .

[0022] Load control devices can control electrical loads within a room and / or building. Each load control device may be capable of directly controlling the amount of power provided to the electrical load in response to communications from the input device. Example load control devices may include lighting devices 112, 112a, and / or lighting devices 122 (eg, load control devices in light bulbs, ballasts, LED drivers, etc.). Load control devices may also ...

Abstract

A load control system (100) includes a control device for controlling an electrical load. The control devices include: load control devices, such as for controlling lighting devices (112, 122); and input devices, such as remote control devices (116) configured to send digital messages including lighting devices for controlling lighting loads. Control instruction. When a user interface event is determined to be an "on" event or an "off" event and the number of multicast messages sent within a predefined time period exceeds a predefined threshold, the remote device (116, 150) or hub device (180) may Send digital messages as unicast messages. The remote device (116, 150) or hub device (180) can calculate the delay between the sending of each unicast message. A delay can be injected between unicast messages to help ensure that the communication link is free before the device sends the next unicast message.

Description

[0001] CROSS-REFERENCE TO RELATED APPLICATIONS [0002] This application claims priority to US Provisional Patent Application No. 62 / 358,555, filed July 5, 2016, the entire disclosure of which is incorporated herein by reference. Background technique [0003] For example, various types of load control systems may be used to configure user environments such as residential or office buildings. Lighting control systems can be used to control lighting loads in a user's environment. Lighting control systems may include various devices capable of communicating via radio frequency (RF) communications, such as input devices and load control devices. For example, a remote control device may be used to communicate with a lighting device (eg, a light bulb) in a load control system to control the lighting level of the lighting device. The devices may communicate in the network using RF communications such as: communication; communications; or proprietary communications such as CLEAR...
