Claim:
1. A backup sump pump remote monitoring system comprising: control circuitry integrated into a portable housing, the backup sump pump connected to the control circuitry, the control circuitry to be powered by a line power and when the line power is not available, the control circuitry to be powered by a battery power, the control circuitry including a pressure transducer, the pressure transducer to measure a pressure in a fluid level sensor indicating a change a fluid level that indicates whether the fluid level is rising or falling, and based on the measured pressure and the change in the fluid level, the control circuitry adjusts a speed of the backup sump pump; a pulse width modulator, the pulse width modulator connected to the control circuitry and the backup sump pump, the pulse width modulator to provide a pulse width modulated signal to the backup sump pump, wherein the control circuitry monitors a relative current draw of the backup sump pump by measuring a pulse width of the pulse width modulated signal provided to the backup sump pump to indicate a fault; and a wireless controller connected to the control circuitry, the wireless controller for wirelessly receiving monitoring instructions and wirelessly transmitting backup sump pump status data and an indication of the backup sump pump status data based on the relative current draw, the control circuitry providing an indication of the backup sump pump status data to a remote user device.
