Aspects of the present disclosure relate to a downhole device including an actuator which has a primary purpose to operate the device while also having a secondary purpose to induce controlled pulses into a downhole environment at a first location for detection at a second location. A control package can be connected to the actuator. The control package is operable to detect a trigger event and control the actuator to cause the controlled pulses in the downhole environment in response. In some aspects, the trigger event is the reception of a command sent to the downhole device from the surface and the controlled pulses serve to provide a feedback signal receivable at the surface.
