Hello @kl3m3n,

mqttClient.publish(&In[0], "|RTC UID:rtc1 RTCE:0 HID:rtc\r\n"); // Disable RTC

if i use this, the time is correct but it go few times on the callback, but i only need it one time!!!!!!!!!
mqttClient.publish(&In[0], "|RTC UID:rtc1 HID:rtc\r\n");

mqttClient.publish(&In[0], "@rtc1 RTCF:"yyyy-mm-dd hh:mm:ss" RTCE:1\r\n");

void parseGuioMsg(const String &msg) {
if (msg.startsWith("@rtc1")) {
getRtc = 1;
mqttClient.publish(&In[0], "@rtc1 RTCE:0\n\r"); // Disable the RTC

Thank you
Best regards

@Sato said in command that returns the date and time and the day of the week:

2025/17/12

Show on callback
RTC @rtc1 2025-37-13 20:37:01 dev:W 0001 x.x uuid:d3f1c986-16

No, it not works, the date is wrong 2025/37/13, the time is correct

Thank you
Best regards

Hello @kl3m3n,

Now it works.

@rtc1 2025/17/12 20:17:05 sábado dev:W 0001 x.x uuid:d3f1c986-16b3-47

In this case, the WeekDay is sábado = Saturday. My question is how is the WeekDay, if the Guio is used in UK or Germany and so on...

Saturtday or Samstag or?

Thank You
Best regards

Hello @kl3m3n,

You are right, but i continue have a problem with RTC, the ddd show not the dayofweek. Have you a idea what it is wrong?
Thank You

void generateTheGUI {
getRtc = 0;
Serial.println("Create command RTC");
mqttClient.publish(&In[0], "|RTC UID:rtc1 HID:rtc\r\n");
app_on = 1;
}

Main loop {
//only one time
if ((app_on == 1) && (getRtc == 0)) {
//mqttClient.publish(&In[0], "@rtc1\n\r"); ////same output on Serial Monitor
//mqttClient.publish(&In[0], "@rtc1 RTCF:hh:mm:ss ddd RTCR:5.0\n\r"); //same output on Serial Monitor
mqttClient.publish(&In[0], "@rtc1 RTCF:'hh:mm:ss ddd' RTCR:1.5\n\r"); //same output on Serial Monitor
delay(150);
mqttClient.publish(&In[0], "@rtc1 RTCE:0\n\r"); //Disable RTC ??????????????
getRtc = 1;
delay(150);
}
}

void parseGuioMsg(const String &msg) {
if (msg.startsWith("@rtc1")) {
Serial.print("Show RTC ");
Serial.println(msg);
}
}

On Serial Monitor, a few times, like this...
Show RTC @rtc1 2025/07/07 22:32:31:696 dev:W 0001 x.x uuid:d3f1c986-16b3-47
End Parse
Show RTC @rtc1 2025/07/07 22:32:33:696 dev:W 0001 x.x uuid:d3f1c986-16b3-47
End Parse
Show RTC @rtc1 2025/07/07 22:32:34:694 dev:W 0001 x.x uuid:d3f1c986-16b3-47
End Parse

Hello kl3m3n,

Now i receive the callback @rtc1. The ceation of the command was on the wrong part of the code.

Sorry and Thank You

Best regards

Thank you @kl3m3n,

I've tried this, but it doesn't work, what mistake am I making?

  Serial.print("MQTT CONECTED " );
  Serial.println(mqttClient.state());
  mqttClient.subscribe(&Out[0]); //subscrive topic

mqttClient.publish(&In[0], "RTC UID:rtc1 HID:rtc\r\n");

Main loop {
//for testing every 1000ms
Serial.println("Get rtc ");
//mqttClient.publish(&In[0], "@rtc1 RTCF:'HH:mm:ss' RTCR:2.0\n\r");
mqttClient.publish(&In[0], "@rtc1 RTCF:HH:mm:ss RTCR:2.0\n\r");
}

void parseGuioMsg(const String &msg) {
Serial.print("Callback Gui-O ");
Serial.println(msg); // @init usr: //// here without reaction

if (msg.startsWith("@rtc1")) {
Serial.print("Show RTC "); // here without reaction too
Serial.println(msg);
}
}

Hello @kl3m3n,

Thanks, after all this already exists in Gui-O, Real-time clock (RTC)

I should have paid more attention when reading the manual, I'm sorry to be bothering you with something you've already implemented and from what I can see, a long time ago.

In the next few days I'll check it out and use it to get the MCP7940 right.

Thank you
Best regards

Hello @kl3m3n,

Sorry, that's now correct
