- PZem to ESP32 Wiring & Code using Hard Serial2
My Library and Code:
github.com/AtherSaleem/Pzem017
Original Code :
solarduino.com/pzem-017-dc-en...
PS/Edit : Why I think , it will be difficult to use PZem library and ModBusMaster library together is becuase use of Declaration -- ModbusMaster node; -- in the code, which is common for both, I tried to overcome this but due to knowledge limitation couldn't make it work, so some experienced programmer may correct it at GitHub.

Awesome! I've been trying to get my 300A one to work with modbus and MQTT for ages! thanks so much. Legend!
what if it reads more than one sensor PZEM-017
thank you for explain
can u explain about procedure to change address, is it same like pzem 004?
I have only one such device which is currently deployed, need to detach and test before I could answer this query
Itried to use the PZEM software on Windows 10 but it is not working. Tried to run it in compatibility mode, I get some response but the application still does not load. Any advice on how to make it work with Windows 10 Home
Didn't tried on windows
Do you have Pzem Manual, I recall communication protocol was given in it
If you don't have one, I can try to find it , in my junk
I used the qmodbus application to send commands to the device and it worked ok for me
I will try using python or even an arduino to send the same command strings. I didn't realize I could get all the meter readings in one command which is great.
how about using 2 or more pzem-017? Thanks sir
I think that should not be an issue, as RS485 can talk with multiple equipment on same wiring, just Address of each pzem should be differnt, I have not tried multiple Pzem-017 but have some experince with Pzem-004t, Due to current limitation, you should be able to use upto 4 Pzem-017 easily. Pzem-004t multi example will help you modify the code
Can I use it to measure more than 100 amps ?
Not Sure, if external Ring can give correct measurement above 100A
Can for bidirectional reading
Sorry couldn't get the question. How to do bi directional?
I tried it but not working, "Failed to read modbus" what wrong?
Can I know your setup, pin connections, tx Rx blink status, Pzem model number
@@545sytes pin GPIO 16, 17, RX TX, RX blink but tx no in konverter RS485, I used PZEM017, Please help sir
@@Sarjanandeso check video around 9:20, Tx should blink, instead of Rx, check your wire connection, try replacing tx Rx wires, I hope Pzem address is same as you are using in ino/sketch
@@545sytes the cable connection seems to be correct, how to know pzem address? is there a setting in step 2?
@@Sarjanandeso the default address is either 0x00 or 0x01, try using these in your sketch
I'm having real trouble getting the reset to work. It runs the code but nothing resets. Do you have an email address I could maybe send you my code to take a look for me please?
Don't have spare DC Pzem , as the one I had already been deployed, anyways you can contact me at Gmail using ContactAther as id
software pzem003 not working 😭
I recall pzem003 has different serial setting, 8N1 whereas Pzem 017 works on 8N2, plus modbus master library should be not be used with custom library. Though it is difficult to comment, without knowing actual issue
