The primary distinguishing characteristic of this sleeping device type is the 'Beam' signal - a special extended Z-Wave preamble that instructs FLiRS devices to wake from the sleep state.Ī FLiRs device, in addition to adhering to Section 3 of the Z-Wave Plus Role Type Specification, MUST:īe battery powered and support the Battery Command Class Frequently Listening Routing Slaves (FLiRS) #Ī device that needs to respond to commands, for example, a battery-powered doorlock that conserves energy but still wakes to receive lock and unlock commands is called a Frequently Listening Reporting Slave (sometimes also known as a Listening Sleeping Slave or Sleeping Actuator). Note that neither Sleeping Role Type allows a device to act as a repeater, an SIS, or a setup controller, and that both Sleeping Role Types MUST be battery powered and support the Battery Command Class. The figure, below, duplicates the overview of Z-Wave Plus Sleeping Role Types that appear in this specification. The two Sleeping Role Types outlined in the Z-Wave Plus Role Type Specification are Listening Sleeping Slaves (FLiRS) that can be controlled at any time, whereas Reporting Sleeping Slaves notify a controller device when it is available to receive messages. To permit devices in the Z-wave ecosystem to switch off high-power components, the Z-Wave specification defines "Sleeping" role types which designate devices that enter a low-power state in a controlled manner.
