Hose reel with a drum, driven in an appropriate manner by a motor, and provided with a hose through which a medium can flow, which hose is appropriately connected to a tool at one far end provided with a control to operate this tool, i.e. to start and to stop it, and whose other far end is appropriately, either directly or indirectly, connected to a supply line, characterized in that the hose reel includes a detection module, which has a detection body, a signal sensor and a processing unit. The detection body can detect every flow and/or interruption of the flow of a medium resulting from the operation of the control, and can signal or transmit this to the processing unit which can read possible flow pulses or sequences on the basis of a pulse scheme so as to create one or several control signals.
