UK Power meter monitor


[john] sent in his version of a power meter monitor. It’s designed to monitor the blinking light on the meter to monitor the current power usage. The light flashes in proportion to the amount of power being used, so it was a matter of using a ldr/photoresistor to capture the output and feed it to the parallel port of his computer. To finish it up, he used a shell script to feed the data into MRTG.
