hi @jade7272 -
Thank you for your reply. I just had a look at one of your previous posts. I wish I have seen this before I started 
I went with the ACS722 due to the good reviews it receives and the initially the code seemed simple enough. Of course I never realised all code examples was all done measuring DC and not AC. Nevertheless, I persisted and managed to get the results as per the image below:
I used a 1A light bulb to simulate load at 220V. I am improving my code to measure at increments of 1ms, taking 500 readings and then calculating the current. Finally posting every 1s as permissible in Particle Cloud.
I will post my project as soon as I am done. I tried several PCB manufacturers but for some reason they seem much more expensive, so I went with PCBWay again. Happy with their quality aso far, even with this PCB containing both HV and LV on the same (and quote small) board.
Thanks again for your reposes, it is much appreciated!
Regards,.
Friedl.
