IoT based Smart Energy Meter using NodeMCU ESP8266

We are building Smart Energy Meter using IoT. Here we will use PZEM-004T AC multifunction Electric Energy Metering Power Monitor module to measure the parameters and will use NodeMCU ESP8266 to post the data to an HTML Webpage.

Great

[@adilshaj8333]

i did exactly the same and it was working but now it returns values as 0.00 for all the parametres whyyy?????

[@satyabratasahoo2766]

please share me the hole code of this project i am working on this project
i am not understand this project

[@nupurpurohit6841]

Using the exact same setup, I'm unable to get the readings, it just shows "nan" for all the parameters. Any suggestions??

[@basileldho7789]

Any suggestions?

[@yogeshraj5331]

Yes infinite suggestions

[@gowthamkumar5477]

I suggest d1 and d2 (NodeMCU) or interchange the rx and tx pins

[@sideshn4738]

It showing nan not the value what i do any suggestions
