Claim 0:
1. A sump pump monitor for a sump pump in a pit, said sump pump including a pump, an AC electric power source plug, and an automatic float switch, said sump pump monitor comprising:
(a) a portable housing including a plurality of walls;
(b) an AC electric plug receptacle physically supported by one of the walls of the housing, the AC electric plug receptacle configured to receive the AC electric power source plug of the sump pump to enable the sump pump to continuously receive AC electric current through the sump pump monitor to enable the automatic float switch of the sump pump to turn the pump of the sump pump on when a water level rises above a predetermined level in the pit and to turn the pump of the sump pump off when the water level is below the predetermined level in the pit;
(c) an AC electric power plug physically supported by the housing and configured to be plugged into an AC electrical power source, wherein the housing, the AC electric plug receptacle, and the AC electric power plug are configured to enable the sump pump to continuously receive AC electric current through the sump pump monitor from the AC electrical power source and enable the sump pump to turn itself on and off;
(d) a transmitter physically supported by and positioned in the housing, the transmitter configured to: (i) send out wireless signals through an electronic communication network to a remote signal receiving device, and (ii) receive wireless signals from the remote signal receiving device through the electronic communication network;
(e) a light emitting indicator supported by the housing, the light emitting indicator configured to emit at least two different colors, and configured to emit one of the colors to indicate that the sump pump is not working properly;
(f) an onboard computer physically supported by and positioned in the housing; and
(g) an AC electric current characteristic detector physically supported by the housing and configured to continuously monitor an AC electric current characteristic of the AC electric current supplied through the sump pump monitor to the sump pump to detect a plurality of different AC electric current characteristic levels above zero of the sump pump including an operating AC electric current characteristic level of the sump pump, and to operate with the onboard computer and the transmitter to send out signals to the remote signal receiving device to: (i) cause a user access device separate from the remote signal receiving device to display an indication of normal operation of the sump pump; and (ii) determine of a variation from a first normal operating AC electric current characteristic level above zero for the sump pump to a second different non-normal operating electric current characteristic above zero for the sump pump based on a normal operating AC electric current characteristic of the sump pump, wherein any such determined variation in operating AC electric current characteristic level itself is used to determine a failure of part of the sump pump and to cause the user access device to display a warning regarding the failure.
