One of the critical factors which can lead to beam degradation is the thermal drifts and the mechanical inertias present in the optical elements, such as a monochromator. This article shows a new functionality of the ALBA Electrometer (Em#), which ensures that the beamline receives the maximum possible beam intensity during the experiment. From the current reading of an ionization chamber and driving the piezo-actuator pitch of the monochromator, the Em# implements a Perturb and Observe (P&O) algorithm that detects the peak beam intensity while tracking it. This feature has been tested on NOTOS beamline and the preliminary results of the performance are shown in this paper.
