An event-driven library for ESP32 implementing PZEM-004T v3.0 / PZEM-003 / PZEM-017 Modbus-RTU proto

pzem-edl's Issues

LList.h is missing (does not exist)

I can’t even run the example because the LList.h is missing, even Google can’t find it =((

Multiple PZEM example - Single Variable Compile Error

Hi @vortigont, thanks for the nice Lib!

Im not a specialist in Programming, so I need to aks some silly questions.

I Use 3x PZEM and they work great with your example code.

pz004::rx_msg_prettyp(m); Gives me the Whole list of Values of the Boards wich is great!

What I need to do is only get Voltages / Currents / Power etc. and write them in custom variables.

I tried this from the main.cpp to get the current from one Sensor:

void mycallback(uint8_t id, const RX_msg* m){

auto *m = (const pz004::metrics*)meters->getMetrics(PZEM_ID_2)
Serial.printf("PZEM '%s' current as float: %.3f (Amps)\n", meters->getDescr(PZEM_ID_2), m->asFloat(meter_t::cur));

But it wont compile and gives me errors.

I also dont need floats, so raw Integer values would be enough for me.

how do I access the single values within the callback (Raw values & Floats)?

Thanks in advance!

esp32/spiram.h is missing

@vortigont , after updating to new version of this library, I get an error while compiling "In file included from espem/espem.h:12:0,

and an error in the main.cpp also as shown in the screen shot below

Your examples do not compile in Arduino IDE

Swears like this -

from C:\Users\User\Documents\Arduino\libraries\pzem-edl-main\examples\03_MultiplePZEM004\src\main.cpp:14:

compilation terminated.
exit status 1

What to do?

Multiple instance example crashes

I've setup my PZEMs as per the CLI instructions and run the sample. Only change is that my GPIO pins are 16 and 17. So changed

#define RX_PIN 16           // custom RX pin number
#define TX_PIN 17           // custom TX pin number

Upon running the example crashes with:

loop() not working / Execute own program Code Example.

Hi @vortigont,

It´s Me again. I had success with the Signale Values, now I tried to add some stuff to loop() and it is not working.

this kind of Programing is new to me, can you give a newbie a example on how to execute my "own" code? with your Library?

Sorry for these kind of questions, but i would love to use ur Library for my projekt.

Thanks in advance.

Missing UART library?

Trying to get your code to compile.

msgq.hpp:14:10: fatal error: driver/uart.h: No such file or directory

pzem-edl/src/msgq.hpp

Line 14 in 9750b66

#include "driver/uart.h"

What am I missing library-wise?

Resetting energy counter

I can't find a way to reset the power meters back to zero. I.e. a Energy counter reset

From https://github.com/mandulaj/PZEM-004T-v30/blob/master/src/PZEM004Tv30.cpp

/*!
 * PZEM004Tv30::resetEnergy
 *
 * Reset the Energy counter on the device
 *
 * @return success
*/
bool PZEM004Tv30::resetEnergy(){
    uint8_t buffer[] = {0x00, CMD_REST, 0x00, 0x00};
    uint8_t reply[5];
    buffer[0] = _addr;

    setCRC(buffer, 4);
    _serial->write(buffer, 4);

    uint16_t length = receive(reply, 5);

    if(length == 0 || length == 5){
        return false;
    }

    return true;
}

Значение потребленной мощности в киловатт часах, сбросилось и начало считать заново

{"age":245,"U":200.1,"I":10.79,"P":2104,"W":16976,"hz":50.0,"pF":0.97}
Вчера значение когда подключил esp значение показало 52квч, хотя на прошивке тасмола было 378 квч, сегодня же значение пошло считать заново, при этом достало примерно до 65квч и сбросилось, мое предположение что это проблема может быть в переменной unsigned int у которой значения 0… 65 535
