Best method to measure power consumption for smart plug / light switch etc..
-
Hello,
What do you use to measure the power consumption ? accurate, easy, cheap and don't break down easily.
I know about the ACS712 but the reviews in sparkfun are not so good : https://www.sparkfun.com/products/8883
What do you think ?

@ahmedadelhosni I just love the INA219
-
That is a current sensor, so unless you take power factor into account, your measurements will not be very precise. I think the easiest way would be to get a sonoff pow, unless you really want to go DIY

INA219
Is this for AC loads ? I guess this is for DC

@gohan sonoff does power measurements ?
I need DIY for my projects. I don't want to use already manufactured products.

@ahmedadelhosni yup. You didn't say this was a requirement
