Use the ACS712 to monitor my house energy use?

Hi Pavel,

You may want to take a look at this:

Emonlib and ADS1115 on Wemos

I’ve searched a lot now, but am still unsure if this is possible, and it so, how it can be done. I want to monitor current of three phases (SCT clamp sensors) and voltage (ZMPT sensor), all outputing voltage. This works fine if i use the single analogue input of the wemos, but as it has only one, it used the external ADS1115 connected via I2C. Does emonlib still need the analogue pin entered in the sketch - eg. emon1.current1(1, 111.1), or is there a workaround for the ADS1115? Any help real…

Bottom line: using an ADS1115 is an excercise in futility. The ADC sample rate is too slow.
The thread at the link above explains why. It’s a quick read. There are only 8 posts in total.
