Hi.
You can use this tutorial as a reference to learn how to get time from the NTP server with the ESP32: https://randomnerdtutorials.com/esp32-date-time-ntp-client-server-arduino/

Hi folks !
I’m using your sketch to send simple email and it works very nice.
Now i’would like to put ntp time (hour only) in a variable to make some actions based on
period of the day. I’saw that you configure NTP server in the setup.
Is there a way to use that time ?

Thanks !

In reply to Allen Mulvey. I also had trouble compiling for ESP8266 boards. Your method of changing the file name helped. Thanks

Hello Sara,
this is a great tutorial, easy to follow.
just wanted to know how to change the text message depending on different conditions.
like for example:
if (condition 1) {
message 1;
}
else if (condition 2) {
message 2;
}

I am sadly not that experienced in arduino programming, so i do not know what to do.
please help me out.

Hi Sara,

Just one more thing.

My ESP8266 code collects temperature and humidity values.
The values are sending to a database.
If the values are out of a tolerance zone, sending by e-mail.
There is incremental hour step (2 hours / sending) in the e-mail date-time stamp

Real time period
18/08/2023 21:51 to 22:00

E-mail Database

# °C RH% Date Time Date Time
1 27,6 64,5 18/08/2023 21:49 18/08/2023 21:51
2 27,51 64,67 18/08/2023 23:49 18/08/2023 21:52
3 27,4 64,93 19/08/2023 1:48 18/08/2023 21:53
4 27,3 65,45 19/08/2023 3:48 18/08/2023 21:54
5 27,24 65,46 19/08/2023 5:47 18/08/2023 21:55
6 27,21 65,46 19/08/2023 7:47 18/08/2023 21:56
7 27,17 65,67 19/08/2023 9:46 18/08/2023 21:57
8 27,14 65,72 19/08/2023 11:46 18/08/2023 21:58
9 27,14 65,78 19/08/2023 13:45 18/08/2023 21:59
10 27,12 65,92 19/08/2023 15:45 18/08/2023 22:00
…
etc.

Here is the code detail:

config.time.ntp_server = F(“pool.ntp.org,time.nist.gov”);
config.time.gmt_offset = 2;
config.time.day_light_offset = 0;

How can I solve this issue?

I completly uninstalled the Arduino IDE and I switched to VS system.
All thing is works fine.
I can only repeat myself: this technical blog is awesome. ‘keep it up’

Hello Sara and Rui,

As I wrote in earlier forum comment (DIY Cloud Weather Station with ESP32/ESP8266 (MySQL Database and PHP)) this tutorial page is awesome.
Congratulation!

I have a little problem with this page project: ESP8266 NodeMCU Send Emails…

I’m using Lolin (Wemos) D1 R1 board (its a 8266 based board)
This projec “DIY Cloud Weather Station with ESP32/ESP8266 (MySQL Database and PHP)” working fine on the board.
But unfortunately the Email sending project is not works.

This is the errormessage after the compiling:
