A motorized window treatment may include a roller tube, a covering material that is attached to the roller tube, and a motor drive unit configured to be located within the roller tube. The motor drive unit may include a motor drive shaft defining a motor drive shaft rotational axis in a longitudinal direction. The motor drive shaft may be configured to rotate the roller tube to adjust the covering material between a raised position and a lowered position. The motorized window treatment may be configured to adjust a visible light transmittance of the covering material by rotating the roller tube, for example, when the covering material is in a fixed position between the raised position and the lowered position.

A battery-powered, motorized window treatment may include a fascia that pivots between a conceal position wherein the fascia covers a window treatment assembly and a battery compartment, and an expose position wherein the fascia does not cover the battery compartment. The fascia may be a two part fascia that includes an arm and a cover that pivots relative to the arm when the battery compartment is operated between respective opened and closed positions. The arm may be attached to the battery compartment such that the arm remains in a fixed orientation relative to the battery compartment. The arm and the cover may define complementary pivotally interlocking connectors that define a pivot axis about which the cover may pivot relative to the arm. The fascia may be configured to generate a perceptible indication when the fascia pivots into the conceal position, and/or when the fascia pivots into the expose position.

A motorized roller shade configured to connect to a power-over-Ethernet network includes a motor for rotating the shade to roll and unroll shade material to and from a roller tube to raise and lower the shade. A bank of ultra-capacitors positioned in the roller tube provides power to the motor and to logic and control circuitry also positioned within the roller tube. The logic and control circuitry charges the ultra-capacitors though power derived from the power-over-Ethernet network, without any power-over-Ethernet switches in the network to provide additional power, and controls the operation of the motor to achieve a desired target velocity. Synchronized operation of multiple motorized roller shades is achieved though autonomous operation of the shades by their corresponding logic and control circuitry. In exemplary embodiments, a lighting element controlled by the logic and control circuitry allows controlled lighting of the shade.

A motorized window treatment for controlling the amount of daylight entering a space through a window includes a covering material, a drive shaft, and a motor coupled to the drive shaft for raising and lowering the covering material. The window treatment also includes a spring assist unit for assisting the motor by providing a torque that equals the torque provided by the weight on the cords that lift the covering material at a position midway between fully-open and fully-closed positions to minimize motor usage and conserve battery life. The window treatment may comprise a photosensor for measuring the amount of daylight outside the window and temperature sensors for measuring the temperatures inside and outside of the window. The position of the covering material may be automatically controlled in response to the photosensor and the temperature sensors, or in response to an infrared or radio-frequency remote control.
