1. A system for remote monitoring of refrigeration systems to detect leaks of refrigerant, comprising:
a local monitoring station, having at least one sensor configured to be in communication with a refrigeration system having refrigerant, said sensor measuring at least one parameter of the refrigeration system, said at least one sensor measuring a quantity of refrigerant in the refrigeration system, said local monitoring station further having at least one local processor;
at least one server, remote from and in communication with said local monitoring station and accessible by at least one user communication device via communication channels; and
software residing at least partially on said local monitoring station, wherein said at least one local processor is configured to execute said software to cause said local monitoring station to:
record data from said at least one sensor periodically to generate recorded sensor data;
collect said recorded sensor data over time to generate collected sensor data;
aggregate refrigerant levels over a plurality of time periods of differing sizes, wherein shorter of said time periods are used to identify leaks with a lower amplitude, and wherein longer of said time periods are used to identify leaks with a higher amplitude;
determine via at least one algorithm, using said collected sensor data, whether a refrigerant leak is occurring in the refrigeration system being monitored to thereby generate a state of the refrigeration system; and
communicate said state of the refrigeration system to said at least one server.
