Abstract: A ceiling fan may include a hub having a first end, a second end opposite the first end, a central axis extending through the first end and the second end, and an accessory interface disposed proximate to the first end or the second end. The ceiling fan may also include a subframe disposed proximate to the hub, the subframe being rotatable with respect to the hub about the central axis, a plurality of fan blades extending outwardly from the subframe, and an accessory unit, the accessory unit being removably coupled to the accessory interface of the hub.

Abstract: Devices, systems, and methods for controlling a ceiling fan are disclosed. One example system may include a sensor device and a remote device. The remote device may be configured to generate an instruction based on the data obtained from the sensor device, and transmit the instruction via the communications network to a fan. The fan may include a hub, a plurality of fan blades extending from the hub, and a motor supported by the hub. The fan may further include a wireless transceiver supported by the hub. The wireless transceiver may be configured to access the communications network for communicating with the remote device. The fan may further include an electronic processor supported by the hub. The electronic processor may be configured to control an operation of the fan based on receiving the instruction from the remote device via the wireless transceiver.
