In this talk I discuss recent updates regarding the search for light sterile neutrinos in various classes of experiments with particular focus on the electron neutrino sector. I discuss developments in Gallium experiments, using reactor rate and reactor spectral ratio data, and also searches for light sterile neutrinos in Tritium and solar experiments. I will also briefly discuss searches in the other channels, which are the $\nu_\mu$ disappearance and $\nu_e$ appearance channels.
