Remote control device comprising a generator (PVU) intended to convert light or mechanical energy to electrical energy, a wireless transmitter (RF) able to send messages to a remote receiver, a first electrical energy storage element (C1) connected to the energy generator (PVU) and intended to be charged with the electrical energy generated by the generator (PVU) in order to supply power to the wireless transmitter (RF) in a first operating mode of the control device, and a second electrical energy storage element (C2) intended to supply power to the wireless transmitter (RF) in a second operating mode. The second electrical energy storage element is connected to the generator (PVU) via parallel connection of a first resistor (R1) and a first diode (D1), the cathode of the first diode being connected to the positive terminal of the generator (PVU).
