Thank you for the code, but it is not working for me. I have used pzem-004tv3 module and related code with arduino Uno and it works great.

I'm trying to talk to Arduino Uno, and need (I believe) TTL to rs485 translation. Would you describe how this code is intended to work with pzem-017 module (and arduino Uno)? For example, Modbus library is apparently not used; is the code performing some of those tasks? Also, is a TTL to rs485 module needed? If so, which type is presumed, 2-pin (A,B) or 4-pin (DI,DE,RE,RO)? Thanks.

I am getting the following error when compiling for arduino nano:
....\Arduino\libraries\PZEM-017-v1-master\PZEM017v1.cpp: In constructor 'PZEM017v1::PZEM017v1(uint8_t, uint8_t, uint8_t)': ....\Arduino\libraries\PZEM-017-v1-master\PZEM017v1.cpp:90:32: error: 'SWSERIAL_8N2' was not declared in this scope port->begin(PZEM_BAUD_RATE,SWSERIAL_8N2); ^~~~~~~~~~~~ ....\Arduino\libraries\PZEM-017-v1-master\PZEM017v1.cpp:90:32: note: suggested alternative: 'SERIAL_8N2' port->begin(PZEM_BAUD_RATE,SWSERIAL_8N2); ^~~~~~~~~~~~ SERIAL_8N2 exit status 1

How can I make it compile?
Thanks

Sorry for bad english... :-)
SoftwareSerial example not work , but if remove " SWSERIAL_8N2" in the line 90 it's ok!

still great job!!
