A relay device transfers information between a sensor system, which measures a physiological characteristic level of a user, and a fluid delivery system, which infuses a fluid into a user. The relay device includes a sensor system receiver for receiving communications from the sensor system in a sensor system format. The relay device also includes a processor for processing the communications from the sensor system and converting the communications for transmission in a delivery system format. The relay device further includes a delivery system transmitter for transmitting the converted communications in the delivery system format to the fluid delivery system. The sensor system and delivery system formats may utilize different frequencies and/or different communication protocols for communications transmitted between the sensor system and the fluid delivery system through the relay device.
