A hose control system comprising a receiver and a transmitter by which one can remotely control both the flow of water through a hose and the winding or unwinding of the hose onto a reel. The system preferably has power saving advantages, for example, by the use of a power control unit that reduces the power consumed by the electronics of the devices, but does not unreasonably disrupt the use of the devices. The receiver may be used with different aspects or all of the hose control system.
