Yes, I will post the final code, wiring and instructions on another thread so other users can follows and don’t have to go through all kind off issue that I had
Congratulations, it would be interesting if you would like to share the project with the related code and wiring. So you can do it. Thank you so much .
Without the use of Tasmota and MQTT, but directly connected to Nodemcu, the whole thing is working properly like version V.1.0. Finally after so much sacrifice I succeeded.
Sorry for all the delay on posting the code as I was out of town for 2 months.
I have create a new topic on how to make the wiring connection and the source code for PZEM-004T with ESP8266 so it can display all the data on Blynk app.
One useful feature of the PZEM-004T V3 is that it will retain energy usage data even if you have a power failure. You could just let the KWH increase month by month up to the maximum of 9999 KWH but the assumption is that you will reset the value each time you receive an electric bill. How can i reset this pzem004t v3 ?
@jaggil you appear to have posted the same thing twice, and in both cases you have omitted the triple backticks necessary for the code to display correctly.
Please edit your posts using the pencil icon at the bottom.
If one of the posts is not required then please delete it and add triple backticks at the beginning and end of your code.
Triple backticks look like this:
```
If there is a subtle difference between the two sets of code then please explain the difference between them, and when to use which one.
Hello blynk comm. i also have a problem with pzem 004t v3. i use tasmota on a nodemcu… i have fluctuating readings on my tasmota gui! by the way i have two hot wires on my wall … two 120v and no neutral. i got a reading for a few secs… then zero reading after 2 - 3 secs… i also think the power readings are wrong…
