I am sorry @JoeleDixie, could you clarify what you are referring to the version of? Is that the version of the PZEM board? Also, do you see the same problem...

Ahh, Ok, I see. Hmm, That is interesting indeed. I don't have time to investigate at the moment. But I will look into it later. Is it ok if you...

Could you also try compiling and uploading the sketch using Platform IO? I am curious because I haven't been able to reproduce your problem so far...

Looks like you are not drawing any power or the current transformer isn't attached properly. Make sure to have the current transformer attached on ONE of the TWO wires (Important...

Hey, Sorry I don't have a Seeeduino so can't test it for you. However besides potential problems with SoftwareSerial, I see no reason why it should not work.

I think what might be the problem is the way we conditionally enable SoftwareSerial in the library only on some platforms (AVR and ESP8266). See here: https://github.com/mandulaj/PZEM-004T-v30/blob/b27887e2118f67bda1bb100e6c82a859dafda1c9/src/PZEM004Tv30.h#L49-L52 So perhaps try...

Hey, unfortunately, I don't have experience with Micropython on the ESP32. So unless we find someone who is willing to port this library, we are probably not going to resolve...

Hey @jjtoard, the method you use for determining the power flow is essentially correct. Maybe a more precise definition is that the power flow is negative if the phase between...

When you take the simple product of Voltage and Current, you get something called Apparent Power (`S`). If you have a resistive load, the voltage and current are in phase...
