Hi tpapas,

first, check the code I commend the static IP Ethernet initialization, so to restore It you must uncomment

// start the Ethernet connection and server
//	  Ethernet.begin(mac, ip, myDns, gateway, subnet);

and comment the dhcp initialization

	  if (Ethernet.begin(mac) == 0) {
	    Serial.println(F("Failed to configure Ethernet using DHCP"));
	    if (Ethernet.hardwareStatus() == EthernetNoHardware) {
	      Serial.println(F("Ethernet shield was not found.  Sorry, can't run without hardware. :("));
	    } else if (Ethernet.linkStatus() == LinkOFF) {
	      Serial.println(F("Ethernet cable is not connected."));
	    }
	    // no point in carrying on, so do nothing forevermore:
	    while (true) {
	      delay(1);
	    }

	  }

to change the debounce you must change this define

#define EMAIL_SEND_DEBOUNCE 5*60*1000

Try to change the variable like so (to activate immediately the email send)

unsigned long timeElapsed = millis()-EMAIL_SEND_DEBOUNCE;

and fix this

// Check if value > 30 and check if you already send this email
	if (sensors.getTempCByIndex(0) > 30 && emailSended == false){
		emailSended = true;
		// check if you had already send an email in the last 5 minutes
		if (timeElapsed+EMAIL_SEND_DEBOUNCE < millis()){
			timeElapsed = millis();
			sendEmail();
		}
	}else if (sensors.getTempCByIndex(0) < 30  && emailSended == true){
		// The value return ok and so if you are going over 30 again new notification was sended
		emailSended = false;
	}
 

Give me a feedback, bye Renzo

Hi Arthur,

thanks for suggestion, It’s very interesting.

I must find some time, but surely I add this section.

Thank Renzo

[Renzo Mischianti]

Hi VeloTobi,

I also update the github project, now there is the simple version and the more complex.

Bye Renzo

[Renzo Mischianti]

Hi VeloTobi,

please check the core and library version, I test the sketch width these and It’s work

• Using board d1_mini
• Using core esp8266 2.7.4
• [ESP8266WiFi@1.0]
• [ESP8266WebServer@1.0]
• [WebSockets@2.1.4]
• [WebSockets@2.1.4]
• [Hash@1.0]
• [DHT12_sensor_library@0.9.0]
• [Wire@1.0]

Hi tpapas,
try to add pin 10 HIGH (as documentation)

    pinMode(53, OUTPUT);
    pinMode(4, OUTPUT);
    digitalWrite(4, HIGH);
    pinMode(10, OUTPUT);
    digitalWrite(10, HIGH);

 

and add this code to check If there are some problem

  // Check for Ethernet hardware present
  if (Ethernet.hardwareStatus() == EthernetNoHardware) {
    Serial.println("Ethernet shield was not found.  Sorry, can't run without hardware. :(");
    while (true) {
      delay(1); // do nothing, no point running without Ethernet hardware
    }
  }

  if (Ethernet.linkStatus() == LinkOFF) {
    Serial.println("Ethernet cable is not connected.");
  }

I don’t have a w5100 shield, but this is a must have :P.

And check if shield is fitted good, sometime the problems is more simple than expected.

Bye Renzo

[Renzo Mischianti]

We are going quite off topic, so I create a topic in the relative section, and I need some time to check It. But I will response to you in that section.

Weather radio station with Arduino UNO/MEGA Ethernet problem

Bye Renzo

[Renzo Mischianti]

If the email work the ethernet work, the arduino clones, usually, work like a charm,

With this information It’s very difficult to do a debug.

You must give me more information, what kind of problem do you have?

Bye Renzo

 

[Renzo Mischianti]

Hehehehhe, I’m moved 😛

For the recipient you can follow the instruction on the article

Send email with attachments (v2.x library): Arduino Ethernet – 1

there is an example on library

Distribution list example

and the relative forum topic

EMail distribution list – more than one recipient

If you have some trouble write here.

Bye Renzo

[Renzo Mischianti]

Hi tpasas,

you are right, i put not clear label,

<YOUR-SENDGRID-API-KEY> is the user or apikey name, by default, if i remember, is ‘apikey’,

 

YOUR-SENDGRID-PASSWD> is the key generated the long string.

 

<FROM-EMAIL> is the verified email address sender.

 

I think now is more comprehensive.

 

When i have time i write a little guide.

Bye Renzo

[Renzo Mischianti]

you must set the from (in the declaration of EMailSender) the verified email, I think It’s sufficient, I don’t remember other operation.

Bye Renzo

[Renzo Mischianti]

Yes, all credential is encoded in base64.

Bye Renzo

[Renzo Mischianti]

Hi tpapas,

Next I try to free some memory from my library or do something alternative for Arduino UNO.

Now to use SMTP you must follow this step

https://sendgrid.com/docs/for-developers/sending-email/getting-started-smtp/

and

https://sendgrid.com/docs/for-developers/sending-email/integrating-with-the-smtp-api/

First you must validate the sender email than create api key to use as login and passwd.

If you have problem, write here.

Bye Renzo

[Renzo Mischianti]

Hi tpapas,

It’s the memory usage, i need to recreate the context and try to do some trick to work with this few memory.

I think for now the better solution is to get an Arduino Mega and retry, UNO had very low stats.

But i try to keep in work your configuration when find some time.

Bye Renzo

[Renzo Mischianti]

Yes,

Try to uncomment the EMailSender debug also.

#define EMAIL_SENDER_DEBUG

With this define uncommented you must receive all the client request response.
