Hi,
I'm facing problem with PZEM004T v4.0 since fifteen days. I have used various codes from Deepseek, Perplexity and Co-pilot compiled in the Arduino IDE for Arduino Uno R4 Minima & ESP32-WROOM-32UE, generated code (energy metering and monitoring) seperately for both boards.
I have tested these codes for control & monitor for electrical devices, appliances using relay modules, SSR, OLED/TFT Display, ZMPTP101B, DC fan, etc connected to Uno/ESP. All of the codes start working perfectly fine after some 2 or 3 error while compiling the code.
But the issue with PZEM remains same, no result after numerous attempt.
I have used various codes to check and verify if the communication protocol has some issues or if it is not getting proper power supply but everthing is fine.
Please can you modify or cross-check with datasheet of PZEM004T v4 for the given below libraries I have used:-
GitHub - mandulaj/PZEM-004T-v30: Arduino library for the Updated PZEM-004T v3.0 Power and Energy meter
GitHub - mqu/esp32-pzem-004t: PZEM-004T energy monitoring using ESP32, autoconnect, influxdb, chronograf
Thanks
