Multiple HLW8012

[abhi-ratnman]

Hey Xose, I am working on a Home Automation product which will be able to send Energy Measurement using this HLW8012 module (Link: https://www.electrodragon.com/product/energy-meter-hlw8012-breakout-board/). Thanks to you we were able to work with 1 Module. The problem comes when we try to connect multiple modules with same MCU giving them power from an isolated source(Hi-link HLK-PM01) the problems is when we switch on one HLW8012 the other HLW8012 module which is connected to power source (Hi-link HLK-PM01) but the switch is off still gets the AC power which in-turn switch on the device.

Please Help us with guiding for developing a module which is able to Get power reading from 4 different Appliances using the same isolated power source.

Thanks,
Abhi Ratnman

Hi Abhi. Sorry I don't know the solution to your issue but I am stuck at what you have already achieved. I too am using the breakout board, but am only getting zero readings. I tried both the basic.ino as well as the interrupt.ino from this library. Is this me only or you also faced issues with the board? If you were able to fetch readings smoothly in the first place then maybe its an issue with my board.
I have attached images of my setup and the readings I get.
