    Abstract: 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.

    Abstract: To provide a mechanism that can further improve security of an electronic key installed in a vehicle interior.
    There is provided a housing device configured to store an electronic key configured to perform wireless communication with an in-vehicle device mounted on a vehicle, the housing device comprising: a housing formed by using a material that shields a first signal transmitted by the in-vehicle device; a trigger signal reception antenna configured to receive a trigger signal transmitted by a portable device carried by a user; and a control mechanism configured to control whether or not to enable the first signal to reach an inside of the housing based on the trigger signal, wherein the second signal transmitted by the electronic key that has received the first signal is used to control a control target device installed in the vehicle.
