A method of controlling a network of refrigeration systems, comprising: receiving measurements captured at a plurality of refrigeration systems, the measurements including measurements of temperatures and electrical currents that characterize performance of each of the plurality of refrigeration systems ; determining at least one refrigeration system of the plurality of the refrigeration systems that is performing below an optimal level and initiating a repair process for the at least one refrigeration system , characterized by generating one or more post-repair baselines after the at least one refrigeration system has stabilized after having been repaired by monitoring the at least one refrigeration system for a predefined period of time, wherein the one or more post-repair baselines relate to post-repair durations of thermodynamic cycles or energy usage; and comparing the one or more post-repair baselines with corresponding pre-repair baselines generated from measurements obtained from the at least one refrigeration system to determine whether the at least one refrigeration system is performing at the optimal level or above for a predefined period of time after the at least one refrigeration system has been repaired , wherein the one or more pre-repair baselines relate to pre-repair durations of thermodynamic cycles or energy usage, wherein the optimal level is determined based on the performance of a population of refrigeration systems identified in a history of prior measurements, and wherein the one or more post-repair baselines and the one or more pre-repair baselines are generated from the measurements of temperatures and electrical currents that characterize the performance of the refrigeration system. receiving measurements captured at a plurality of refrigeration systems, the measurements including measurements of temperatures and electrical currents that characterize performance of each of the plurality of refrigeration systems ; determining at least one refrigeration system of the plurality of the refrigeration systems that is performing below an optimal level and initiating a repair process for the at least one refrigeration system , characterized by generating one or more post-repair baselines after the at least one refrigeration system has stabilized after having been repaired by monitoring the at least one refrigeration system for a predefined period of time, wherein the one or more post-repair baselines relate to post-repair durations of thermodynamic cycles or energy usage; and comparing the one or more post-repair baselines with corresponding pre-repair baselines generated from measurements obtained from the at least one refrigeration system to determine whether the at least one refrigeration system is performing at the optimal level or above for a predefined period of time after the at least one refrigeration system has been repaired , wherein the one or more pre-repair baselines relate to pre-repair durations of thermodynamic cycles or energy usage, wherein the optimal level is determined based on the performance of a population of refrigeration systems identified in a history of prior measurements, and wherein the one or more post-repair baselines and the one or more pre-repair baselines are generated from the measurements of temperatures and electrical currents that characterize the performance of the refrigeration system. <EOS>
