Abstract: A thermostatic control device for a thermostatic mixer tap has a temperature sensor that measures the temperature of a mixed fluid, a flow rate sensor that measures the flow rate of the stream of the mixed fluid when the control device is in a flowing state, and an incorporated electronic circuit having a programmable electronic computer, a communication interface provided with a radio antenna, and an electric energy reserve, capable of powering the electronic computer and the communication interface. The electronic circuit collects information measured by the sensors and transmits this information to the outside via the communication interface.
