NO LOAD READINGS ARE FUNNY about hlw8012 HOT 3 OPEN

Did this work for you afterwards? I'm also seeing occasionally every 30 secs, Voltage and Current values are Crazy ~ Volgate around ~12340 (jump from 226-230) and Current ~426 (jump from 0.3 A)

I have also use 20W blub with 204AC but the values are wired. look at the picture.

There are some reading with zero values.

Hello, the readings as per load are ok but this is due to toggling of Voltage and Current reading pin, From the Reading pin of IC Voltage readings are available when it is high and Current readings are available when it is low( or maybe vice versa pls check it in datasheet). So you have to make an if loop based on which you will get the readings of both voltage and current readings simultaneously.

Other issue i can spot is. If you are using 20W lamp then there is problem in calibration of your load, because power factor should be unity or 1.
