The invention claimed is: 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. 2. The system of claim 1 , wherein the remote user device is a smartphone. 3. 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; 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; 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, the control circuitry providing an indication of the backup sump pump status data to the control panel. 4. The system of claim 3 , wherein the portable housing comprises a first half and a second half, one of the first half and the second half including a heat sink. 5. The system of claim 3 , wherein the wireless controller wirelessly transmits backup sump pump status data only if the wireless controller is first queried by a remote device. 6. The system of claim 3 , wherein the control circuitry measures a pulse width of the pulse width modulated signal provided to the backup sump pump, and the wireless controller provides the indication of the backup sump pump status data based on the measured pulse width. 7. The system of claim 3 , wherein the control circuit determines if the backup sump pump is running at a best efficiency point. 8. The system of claim 7 , wherein the control circuit adjusts the speed of the backup sump pump to allow the backup sump pump to run at the best efficiency point. 9. The system of claim 8 , wherein the control circuit performs the steps of determining if the fluid level is falling; and (a) if the water level is falling, determining if the speed of the backup sump pump is at the best efficiency point and if the speed of the backup sump pump is not at the best efficiency point, decreasing the speed of the backup sump pump; or (b) if the water level is not falling, determining if the speed of the backup sump pump is at a maximum speed and, if the speed is not at the maximum speed, increasing the speed of the backup pump.
