A smarter plug for a home automation system includes a smarter plug sensor and a controller which stores logic for operating the smarter plug sensor. The smarter plug sensor includes three A-D op-amps respectively paired with three resistors having different values forming three different op-amp voltage meters. The three different op-amp voltage meters respectively report a first sensor-voltage slope with a higher sensitivity and a lower range, a second sensor-voltage slope with a lower sensitivity and a higher range and a third sensor-voltage slope with a range and a sensitivity intermediate between these ranges.
