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 input devices, such as a remote control device configured to transmit digital messages comprising lighting control instructions for controlling the lighting load via the lighting device. The remote control device may communicate with the lighting device via an intermediary device, such as 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 to as unicast messages or multicast messages based on the type of user interface event detected.

A motorized drive device includes an electric motor, a first holding device and a first switching mechanism. In a first position of the first mechanism, a first guide wheel of the first holding device is offset relative to a second guide wheel of the first holding device, so as to hold the motorized drive device relative to a rail by supporting the first and second guide wheels with respective first and second tracks of the rail. Furthermore, in a second position of the first mechanism, the first guide wheel is positioned opposite the second guide wheel, in a direction of movement of the motorized drive device along the rail, so as to insert or extract the first and second guide wheels into or from the rail, through a slot of the rail.

A motorized drive device includes a housing, electric motor, drive wheel, first and second holding devices, first elastic return element, drive unit inside the housing, and switching mechanism. The drive unit includes a casing, the electric motor and the drive wheel. The drive wheel is supported on a rail running surface, by the first elastic return element. With the motor activated, the casing inclines inside the housing relative to a median plane of the housing. The switching mechanism drives a first guide wheel of the first holding device between first and second positions, in which the motorized drive device is mounted and dismounted, respectively, relative to the rail. In the first position with the electric motor activated, the drive wheel is supported on the rail running surface, by the first elastic return element which is supported on a wall in the housing and is rotated by the electric motor.

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 input devices, such as a remote control device configured to transmit digital messages comprising lighting control instructions for controlling the lighting load via the lighting device. The remote control device may communicate with the lighting device via an intermediary device, such as 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 to as unicast messages or multicast messages based on the type of user interface event detected.

A solar shading device includes a head rail that slidably supports leading runners having fabric curtains attached thereto, a carrying mechanism that includes a carrying pulley coupled to the leading runners through a belt and carries the leading runners along the head rail on the basis of the rotation of the carrying pulley, a manual drive unit that includes a first shaft coupled to the carrying pulley and serving as a drive shaft, and a suspension part having the manual drive unit suspended therefrom with the carrying pulley and the first shaft coupled together. Further, with the manual drive unit detached from the suspension part, the suspension part allows an electric drive unit to be suspended therefrom with the carrying pulley and a second shaft coupled together, the electric drive unit including the second shaft as a drive shaft for driving the carrying pulley.

A motorized drapery system having an elongated rotating drive element that has a non-circular cross-sectional shape such as square, rectangular, trapezoidal, cross shaped or any other non-circular shape that is twisted. In one arrangement the drive element is twisted in one direction along its entire length. In another arrangement the drive element is twisted in one direction in a first section and twisted in an opposite direction in a second section thereby providing a center opening/center closing drapery. A plurality of rings are positioned around the drive element including at least one driver ring that includes a feature that connects to the drive element and is configured to facilitate movement along the drive element, and a plurality of idler rings that are configured to slide along the drive element. A curtain is connected to the rings and opens and closes as the rings move along the drive element.

A wirelessly controllable, motorized and battery powered drapery apparatus is presented having a rotatable drive element having a guide structure in its surface. The rotatable drive is inserted through the open interior of a plurality of grommets in the shade material. A grommet driver is positioned over the rotatable drive element and connected to one of the plurality of grommets. The grommet driver has at least one tooth that is in communication with the guide structure in the rotatable drive element. As the rotatable drive element is rotated, the grommet drive is driven along the length of the rotatable drive element thereby moving the shade material between an open position and a closed position.

In one or more arrangements, a power efficient remote control system is presented. The remote control system has a touch based interface having a plurality of touch sensitive sensors. The remote control system is configured to operate in an active mode in response to user input and operate in a background mode in response to inactivity. In the active mode, a control circuit of the remote control system is configured to monitor touch activity by sampling signals from outputs from a plurality of touch sensitive sensors individually. In the background mode, power is saved by electrically connecting outputs of the plurality of touch sensitive sensors together and monitoring touch activity by sampling a signal from the connected outputs of the plurality of touch sensitive sensors together.
