I am very well aware of that. Hence why this is a very low priority task. Though I can think of applications where you are forced to move to software...

I am sorry, unfortunately, the library doesn't support the PLC platform at the moment and I am not sure it ever will. Have you considered using the ESP32 to read...

Unfortunately I don't have a Nano 33 IoT. Could you try with the new version v1.1.1 of the library to see if you still face the same issues.

I see what you mean... Huh, I have not thought of this, but reading and deciphering the datasheet, I can't find anything about this feature. Will have a look. Thanks

Reading the datasheet multiple times, I have found nothing about this feature. As we are talking about AC, the current moves back and fourth. In order to determine the direction...

I am going to close this as I suspect that this isn't possible :disappointed:

Hey @milGus, Thanks for your reply! I am intrigued by this information. I was unable to find any information about these registers in the basic PZEM datasheets but if this...

Well the V9401 is the micro controller, though a very simple one. So unless we can get access to the firmware running on it an perhaps tweak it, or if...

> Have you tried accessing beyond the 0x0009 offset? I have not, since the pandemic started I am cut off from my PZEMs so can't do testing of my own......

Hey @marine1988 As was said before, this would require to flash a new firmware onto the PZEM chips. This is far beyond the scope of this library.
