Abstract: Technology relating to a sump pump monitor is provided herein. A sump pump monitor includes a water level sensor to measure a level of water in a pit of the sump pump, an overflow sensor to detect whether an overflow of the water is present in the pit of the sump pump, and a power monitor to monitor electric power delivered to the sump pump. The power monitor is also to transmit one or more signals indicative of an operational issue associated with the sump pump based on the level of the water, the overflow of the water, and the electric power.
