[SOLVED] Problem with Time library and Time input controller

Hello,

I am currently encountering a problem with (I assume) the time.h library and the time input setting controller. The value of my variable used to count the time from 1970 do not send me back the right time. I guess the problem comes from the “hour()” and others functions that don’t send me back the right value of time. It seems to contain the time from the begining of the uploaded sketch.
Usualy when the esp8266 nodeMCU is ready, this value contains around 40 to 60 secondes.
My code is based on several codes find in this forum where all log supplied seem correct so I don’t get what is my problem.

I am using an Esp8266 NodeMCU (http://www.cnx-software.com/wp-content/uploads/2015/10/NodeMCU_v0.9_Pinout.png).
Concerning my config, I have the lastest release of the blynk library (0.4.0) and the latest arduino software (1.6.12). I have tried the 1.6.5 and the 1.6.10 and I encounter the same problem.
All libraries used on sketch supplied on this forum are present in my sketch (probably too much). All libraries are installed on my computer.
I have tried to change some values and to modify my program but nothing changed. I have not seen on the internet any incompatibility problems and even if it has been some issues, my two others tries with older version of arduino software would solve my issue.
I already run some basic sketch permitting to blink a led and it worked well with the blynk app (Android). I don’t find anything on the web to fix my problem.

You can find in attachment my sketch and some logs of my problem. I have make my code much more simpler and the problem is still the same.

Do you have any idea to correct this ? I hope some of you will be able to help me.

By the way, I discovered blynk 3 days ago and the interface is really easy to manage and to use.

Thank you for your work and for your answer.

==> As you can see the nowsecond value is 41 or 52. I am not expecting that.

use the latest library, 1.6.12, which I see you have tried. Stick with this one.

I think your problem is that you are not picking up the time from anywhere.

You need the RTC widget or access to a ntp server before making the connection to the Blynk server.

Just added RTC widget to your sketch and the results are now fine.

#define BLYNK_PRINT Serial    // Comment this out to disable prints and save space

You are right, it works now!!!
I thought the time was included in the basics libraries

Sorry for this waste of time on your side and again thank you for your work and for your kind assistance. I will use Blynk for several project :slight_smile:

Could you upload the sketch? I’m also having problems with TimerInput. Thanks!
