PZEM-016 AC Energy Meter online monitoring with Blynk App using NodeMCU for Solar PV Projects

This project shows you how to DIY online monitoring for AC Energy or Power Meter use Blynk App, NodeMCU and PZEM-016 AC Energy Meter. The system just send data from the commercial Energy Meter to the Blynk Server which has a web interface for online monitoring through its app. It is very suitable for recording Solar PV System or household energy or power consumption. For more information, kindly go to my blog page.

Thanks for doing my request! I will try to do this one. 👍

[@rafaelbailon282]

In return, i will share this video to my page. Hopefully, more subscriber will like your videos.

Need to clarify few things. Currently my battery capacity is around 200A how do I do the changes according to my battery capacity additionally my solar power is around 300V any plugins available to handle both. Thanks

[@dmwarnke1960]

I cant get the code to compile. I get an error "no matching function for call to 'SoftwareSerial::SoftwareSerial()'
The similar code from Everet Dekker will compile but not this version for use with Blynk. Any thoughts?

[@utkarshjha657]

How can we make an app for this, and import data using other IoT app?

Hi I ask if it is possible to see the staples em 1h 6h 1d 1w 1m

Great work sir
But how to automatically reset the energy on blink every 24 Hours ?

[@4kfishing223]

Leaving...
Hard resetting via RTS pin... please help correct this error. thank you

[@anhhiang1445]

Hi , i did follow you but i can not get anything on Serial and blink, i wish you help me, thank you so much

[@RafiRahhim]

what different PZEM-016 vs pzem 004t?

[@youssefodeh9486]

I just knew what is the difference, in PZEM 004t you don't need to buy the communication converter module. you can directly connect PZEM 004t to Arduino. I hope that helps.

[@muhamadnur5982]

what is the name of the base for all modul in the same place?

[@solarduino1374]

Hi, that base I created myself for demo purpose using 3D printing

I do follow you It not working it is show 0 in serial monitor.

Same problem here. Did you find a solution?

@@dmwarnke1960 look at the bottom of the board there is an instruction how to install the driver

[@dmwarnke1960]

@@gerardaldwinpatoc9368 Thanks for the response. I did get the program to compile, I tried
so many things and i'm not even sure what did it. I got closer to it working but i'm still not there. It connects to the Blynk app but i'm not getting any data. It could be the pin connections, i'm not sure. I got a PZEM004
and use a different program and I have the same problem, I connect but no data. When I connect either
unit direct to computer or wifi to computer I get data.

@@dmwarnke1960 i used PZEM 016 we same problem i get zero data to all the parameters when i enter the serial monitor from the Arduino IDE. I followed all the instructions from the link fortunately the code get compiled ad uploaded to nodeMCU but i get zero data. I noticed in the video that the pins are connected to D5 all the way down. not on the D0 to D3. I already messaged @solarduino on his gmail but no response. hope he will response to this

How to save data from this?

[@solarduino1374]

Hi, Blynk app by default already save your data on the cloud. But if you want to get the data locally you can involve Blynk local server (kindly check at Blynk website as I have not tested it before) or adding datalogger module (with some coding) to manually save your record locally.
