If anyone is interested I will publish the details on openhardware.

Yes, please! I am interested in the sketch you are using.

Great work!

Thank you patrik, i already ordered an sct-013-005, but i need sometimes higher measurements than 5a. With this second sensor i will be able to compare the results.

Hello Patrick, thank you for sharing your project. I tested it and it works fine but I want to test how acurate it is with low current measurements. Can you please tell me how to change your code to get results below 60W? I'm just beginning to learn arduino-programming so i don't understand everything..
