Integrate EMONLIB to ESP

[Domenico Carvetta]

Hi Juan,

I tried to run T57 into a ESP sketch using the Emonlib.h library, unsuccessfully.

I got a lot of compilation errors.

Question is: what is the status of the integration of Emonlib library to ESP? I know, by your wiki page, that the other option is read the CT with an Arduino and send the data to the ESP.

[Domenico Carvetta]

Is there someone able to explain what is the meaning for this compilation errors????

If I remove the Emonlib.h from the sketch, the errors disappered!

Dear Juan,

thanks. What about integration of Emonlib library to ESP ?

Have you any input for me ?

[Juan Pinto]

Not yet, I opened a post on ESP forum, but for now I have emonlib working on arduino connected to a ESP for communications, here the post with some hints on the last page:

ok, thanks !!

[Domenico Carvetta]

HI Dario,

one question about the ADC pin on the ESP8266.

In order to read external voltage applied to ADC pin, do I need to "declare" "A0" or "A1", or am I wrong ?

  emon1.current(0, 29.01);                  // Current: ADC input pin, calibration (1800/62ohm)
 

I found that to read external voltage applied to ADC pin, we have to use analogRead(A0).

Can you double confirm me ? Thanks!!

[Di Maio, Dario]

I don't know much about.

Dario.

Hi Juan, back to you :-)

I am trying to upload the sketch "E06_ATTINY_EMONLIB.ino" into a ATtiny85.

First compilation error, should be that SoftwareSerial support only 20,16 and 8Mhz processors.

Did you use to upload using ATtiny85 @8Mhz internal oscillator, BOD disabled core ?

Thanks !!

[Juan Pinto]

You can do with an Arduino and I think will be more easy to get it working for you :P

 

I used an attiny85 without external clock and runing at 8mhz with internal oscillator.

[Domenico Carvetta]

Yes, you are right; I will use first a Arduino :-)

BTW, can you send me the SoftwareSerial.h library you used to upload the attiny85 without external clock and running at 8mhz with internal oscillator ?

I want to double check where is the problem , thanks.

[Domenico Carvetta]

Can I run this code for a Arduino-UNO or need I change something, Juan ?

#include <SoftwareSerial.h>
#include "EmonLib.h"             // Include Emon Library
EnergyMonitor emon1;             // Create an instance




SoftwareSerial TinySerial(3, 4); // RX, TX
#define LED 1
#define CT  A1




void setup()  
{
 // Open serial communications and let us know we are connected
 TinySerial.begin(9600);  // SET TO 1200 ON RECEIVER, I DONT KNOW WHY
 pinMode(LED, OUTPUT);
 emon1.current(CT, 10);       // Current: input pin, calibration.
}




void loop()
{
  float current = emon1.calcIrms(1480);
  TinySerial.print(current);
  delay(100);
  digitalWrite(LED,!digitalRead(LED));
}

[Juan Pinto]

Yes, you can use it, but take care where the pins are defined, (example: pin1 on Arduino is TX so change the led to the pin 13)

 

And you don't need to use SoftwareSerial on Arduino, you can use standard Serial, but this is an option.

So that the new code for Arduino-Uno looks like, can you double confirm me just to make sure, Juan?

[domenico carvetta]

Last question, I apologize ....

And from the E06_ESP_EMONLIB.ino sketch side, I found as follows line 20, but I didn't understand the meaning.

I know that I must connect directly Arduino-Uno Pin1 (TX) to ESP (RX pin), right Juan or am I wrong?

#define Debug Serial1 //Change to Serial1 if you want to use the GPIO2 to TX

[Juan Pinto]

Yes, you'll connect from Arduino TX to ESP RX, this is mandatory.

 

And if you want to use the GPIO2 on ESP to see the debug you will use Serial1 instead Serial.

Hi Juan,

finally I was able to run correctly the T57 for power meter.

I used, as you suggested, a Arduino-Uno, where the TX pin is connected directly to ESP RX.

I didn't used any resistors to match the 5V from the Arduino to the 3.3v for the ESP.

I attached a pictures for your reference.

Next step has been to use a Arduino-Nano in order to minimize the dimensions.

But, although, I used exactly the same configuration, it didn't work and the readings for the T56 and T57 have been nAnn and nWnn.

Do you have any ideas ?

Thanks !!

[Juan Pinto]

It's strange, both Arduino Uno and nano are virtually the same :S

 

Regards

[domenico carvetta]

My opinion is the same; it looks like a bit strange.

I tried to compare both schematics Arduino_uno vs. Arduino-Nano and I found none differences.

BTW, using Arduino-nano it doesn't work.

[Juan Pinto]

You use this example to use the arduino as an usart node.

[Domenico Carvetta]

I used a your sketch to connect the Arduino-Uno (TX) to the ESP (RX). Am I wrong, perphaps ?

#include "EmonLib.h"                   // Include Emon Library
EnergyMonitor emon1;                   // Create an instance

#define LED 13
#define CT  A1

void setup()

 //emon1.current(CT, 10);          // Current: input pin, calibration.
   emon1.current(CT, 29.01);       // Current: input pin, calibration.

}




void loop()
{
    float current = emon1.calcIrms(1480);

    current = current - 0.04;            // valore di offset per la calibrazione
    if (current < 0) current=0 ;                
   
  Serial.println(current);
  delay(1000);
  digitalWrite(LED,!digitalRead(LED));
}

[Juan Pinto]

It's ok

[Domenico Carvetta]

Hi Juan,

can I disturb you again about this topic ?

I want to monitor, from power meter point of view, two different points into my home.  

So that, I have to handle two analog pins ie. A0 and A1 connected to different TA devices.

But I don't know how to assign A0 to the first T57 and A1 to the second T57 using a same serial connection from Arduino to ESP.

Or do I need a second Serial connection?

The original sketch is below:

Arduino sketch:

#include "EmonLib.h"                   // Include Emon Library
EnergyMonitor emon1;                   // Create an instance

#define LED 13
#define CT  A1

void setup()  
{
 // Open serial communications
 Serial.begin(9600);  
 pinMode(LED, OUTPUT);

    emon1.current(CT, 29.01);       // Current: input pin, calibration.
}

void loop()
{
    float current = emon1.calcIrms(1480);
    current = current - 0.04;            // valore di offset per la calibrazione
    if (current < 0) current=0 ;                
   
  Serial.println(current);
  delay(1000);
  digitalWrite(LED,!digitalRead(LED));
}

ESP8266 sketch:

     FAST_710ms()   {
           float current = 0;
           if(Serial.available()){
               float current = Serial.parseFloat();
                           
               Souliss_ImportAnalog(memory_map, CURRENT, &current);
               float watt = current*230;
               Souliss_ImportAnalog(memory_map, WATTS, &watt);
           }
        }

[Juan Pinto]

In this case I suggest you configure your Arduino as peer of  the ESP via USART.

 

Regards

buongiorno Domenico, could you please post your files to check if i got something wrong, thanks
