Hi. In my project I'm solving detecting current. I solved it in low current mains - lights. If any interest, i can write more. But if you want to detect high current, the only solution is to use current transformer <http://www.amveco.com/pdf/AC1010.pdf> . You can use AC1010 to 10A, but there are transformers on higher A. And how to detect it? My solution: raspberry DS2482-100 - i2c to 1-wire converter DS2413P+ - 1 wire switch - perfect chip for controlling devices(on/off). This chip can detect current. It can't detect exact numbers, only on/off. To this chip, connect AC-1010 and you can monitor if in mains are current. I did some testing and on 11-70W devices, voltage on AC-1010 was - 0,8 - 9V (depending on numbers of thread). If you are planning to detect high current, 1 thread will be enough. It must be said, that DS2413P+ has max. 25V, so you can't exceed this limit. At home my devices need low current, so my issue was how to detect low Amps. In your way, there will no problem with current, so you need only to choose proper transfomer. On market are 200Amps transformers (10€).
