PKS 1830-211 is a lensed blazar located at z=2.5. The recent addition of a 28 m Cherenkov telescope (CT5) to the H.E.S.S. array extended the experiment's sensitivity towards low energies, providing access to gamma-ray energies down to 30 GeV. Data towards PKS1830-211 were taken with CT5 in August 2014, following a flare alert by the Fermi collaboration at the beginning of the month. The H.E.S.S observations were aimed at detecting a gamma ray flare delayed by ~25 days from the Fermi flare. These HESS data are presented and discussed.
