Patent attributes
A load control system may include multiple devices capable of communicating with one another to enable load control via a network. Devices communicating in the load control system may be powered by a lower power supply (e.g., a battery). These devices may be power-conservative control devices. A device may transmit an indication that it is a power-conservative control device. The device may be assigned a multicast slot. The multicast slot may occur periodically and may be associated with a multicast phase. An indication of the device's assigned multicast slot may be transmitted to other devices in the load control system. Messages may be transmitted to the device from one or more other devices during its configured multicast slot. The device may periodically transition its communication circuit on and off based on the multicast slot.
