Tell me how many times I can transfer data through the function CAYENNE_OUT??? Is it necessary to use timers to pass values?

you will find everything in this post Sending MQTT messages within rate limits

I saw this post. I’m just trying to understand if I have about 20 values and I will send them through the CAYENNE_OUT function. She will send them every 15 seconds, regardless of the cycle of the main? or how it works is not understood( up to the end.

My code is now like this:
//CAYENNE Температура улица
CAYENNE_OUT(VIRTUAL_CHANNEL_0){Cayenne.virtualWrite(VIRTUAL_CHANNEL_0, TEMP_5, TYPE_TEMPERATURE, UNIT_CELSIUS);}
//CAYENNE Температура кухня
CAYENNE_OUT(VIRTUAL_CHANNEL_1){Cayenne.virtualWrite(VIRTUAL_CHANNEL_1, TEMP_1, TYPE_TEMPERATURE, UNIT_CELSIUS);}
//CAYENNE Температура спальня
CAYENNE_OUT(VIRTUAL_CHANNEL_2){Cayenne.virtualWrite(VIRTUAL_CHANNEL_2, TEMP_2, TYPE_TEMPERATURE, UNIT_CELSIUS);}
//CAYENNE Температура гостиная
CAYENNE_OUT(VIRTUAL_CHANNEL_3){Cayenne.virtualWrite(VIRTUAL_CHANNEL_3, TEMP_3, TYPE_TEMPERATURE, UNIT_CELSIUS);}
//CAYENNE Температура детская
CAYENNE_OUT(VIRTUAL_CHANNEL_4){Cayenne.virtualWrite(VIRTUAL_CHANNEL_4, TEMP_4, TYPE_TEMPERATURE, UNIT_CELSIUS);}
//CAYENNE Влажность кухня
CAYENNE_OUT(VIRTUAL_CHANNEL_5){Cayenne.virtualWrite(VIRTUAL_CHANNEL_5, HUM_1);}
//CAYENNE Влажность спальня
CAYENNE_OUT(VIRTUAL_CHANNEL_6){Cayenne.virtualWrite(VIRTUAL_CHANNEL_6, HUM_2);}
//CAYENNE Влажность гостиная
CAYENNE_OUT(VIRTUAL_CHANNEL_7){Cayenne.virtualWrite(VIRTUAL_CHANNEL_7, HUM_3);}
//CAYENNE Влажность детская
CAYENNE_OUT(VIRTUAL_CHANNEL_8){Cayenne.virtualWrite(VIRTUAL_CHANNEL_8, HUM_4);}
//CAYENNE Батарея кухня
CAYENNE_OUT(VIRTUAL_CHANNEL_9){Cayenne.virtualWrite(VIRTUAL_CHANNEL_9, BAT_1);}
//CAYENNE Батарея спальня
CAYENNE_OUT(VIRTUAL_CHANNEL_10){Cayenne.virtualWrite(VIRTUAL_CHANNEL_10, BAT_2);}
//CAYENNE Батарея гостиная
CAYENNE_OUT(VIRTUAL_CHANNEL_11){Cayenne.virtualWrite(VIRTUAL_CHANNEL_11, BAT_3);}
//CAYENNE Батарея детская
CAYENNE_OUT(VIRTUAL_CHANNEL_12){Cayenne.virtualWrite(VIRTUAL_CHANNEL_12, BAT_4);}
//CAYENNE Давление
CAYENNE_OUT(VIRTUAL_CHANNEL_28){Cayenne.virtualWrite(VIRTUAL_CHANNEL_28, BAR);}

the CAYENNE_OUT function is called every 15 sec regardless of the main loop. just make sure that you don’t have a large delay in the main loop, use inbuilt millis() in place of delay.

That is, in my case, each will be called with a break of 15 seconds? What’s the difference between functions and CAYENNE_OUT CAYENNE_OUT_DEFAULT

6

the CAYENNE_OUT function is written to run every 15 seconds. you don’t need to do anything.
CAYENNE_OUT ----- is for sending one individual channel data.
example:

CAYENNE_OUT(0)
{ 
   Cayenne.virtualWrite(0, millis());
}
CAYENNE_OUT(1)
{ 
   Cayenne.virtualWrite(1, millis());
}

CAYENNE_OUT_DEFAULT — is for sending data of multiple channel together.

CAYENNE_OUT_DEFAULT()
{ 
   Cayenne.virtualWrite(0, millis());
   Cayenne.virtualWrite(1, millis());
   Cayenne.virtualWrite(2, millis());
   Cayenne.virtualWrite(3, millis());
   Cayenne.virtualWrite(4, millis());
}

Ok. Thanks

Can I call the CAYENNE_OUT_DEFAULT () function only once in the program? I just did three of these functions and I do not compile the sketch. As soon as I clean everything compiles.

CAYENNE_OUT_DEFAULT(){
Cayenne.virtualWrite(VIRTUAL_CHANNEL_1, TEMP_1, TYPE_TEMPERATURE, UNIT_CELSIUS); //Температура кухня
Cayenne.virtualWrite(VIRTUAL_CHANNEL_2, TEMP_2, TYPE_TEMPERATURE, UNIT_CELSIUS); //Температура спальня
Cayenne.virtualWrite(VIRTUAL_CHANNEL_3, TEMP_3, TYPE_TEMPERATURE, UNIT_CELSIUS); //Температура гостиная
Cayenne.virtualWrite(VIRTUAL_CHANNEL_4, TEMP_4, TYPE_TEMPERATURE, UNIT_CELSIUS); //Температура детская
Cayenne.virtualWrite(VIRTUAL_CHANNEL_13, TEMP_5, TYPE_TEMPERATURE, UNIT_CELSIUS); //Температура улица
}

CAYENNE_OUT_DEFAULT(){
Cayenne.virtualWrite(VIRTUAL_CHANNEL_5, HUM_1); //Влажность кухня
Cayenne.virtualWrite(VIRTUAL_CHANNEL_6, HUM_2); //Влажность спальня
Cayenne.virtualWrite(VIRTUAL_CHANNEL_7, HUM_3); //Влажность гостиная
Cayenne.virtualWrite(VIRTUAL_CHANNEL_8, HUM_4); //Влажность детская
Cayenne.virtualWrite(VIRTUAL_CHANNEL_14, BAR); //Давление
}

CAYENNE_OUT_DEFAULT(){
Cayenne.virtualWrite(VIRTUAL_CHANNEL_9, BAT_1); //Батарея кухня
Cayenne.virtualWrite(VIRTUAL_CHANNEL_10, BAT_2); //Батарея спальня
Cayenne.virtualWrite(VIRTUAL_CHANNEL_11, BAT_3); //Батарея гостиная
Cayenne.virtualWrite(VIRTUAL_CHANNEL_12, BAT_4); //Батарея детская
}

CAYENNE_OUT_DEFAULT () function only need to called once in the program.

CAYENNE_OUT_DEFAULT(){
Cayenne.virtualWrite(VIRTUAL_CHANNEL_1, TEMP_1, TYPE_TEMPERATURE, UNIT_CELSIUS); //Температура кухня
Cayenne.virtualWrite(VIRTUAL_CHANNEL_2, TEMP_2, TYPE_TEMPERATURE, UNIT_CELSIUS); //Температура спальня
Cayenne.virtualWrite(VIRTUAL_CHANNEL_3, TEMP_3, TYPE_TEMPERATURE, UNIT_CELSIUS); //Температура гостиная
Cayenne.virtualWrite(VIRTUAL_CHANNEL_4, TEMP_4, TYPE_TEMPERATURE, UNIT_CELSIUS); //Температура детская
Cayenne.virtualWrite(VIRTUAL_CHANNEL_13, TEMP_5, TYPE_TEMPERATURE, UNIT_CELSIUS); //Температура улица
Cayenne.virtualWrite(VIRTUAL_CHANNEL_5, HUM_1); //Влажность кухня
Cayenne.virtualWrite(VIRTUAL_CHANNEL_6, HUM_2); //Влажность спальня
Cayenne.virtualWrite(VIRTUAL_CHANNEL_7, HUM_3); //Влажность гостиная
Cayenne.virtualWrite(VIRTUAL_CHANNEL_8, HUM_4); //Влажность детская
Cayenne.virtualWrite(VIRTUAL_CHANNEL_14, BAR); //Давление
Cayenne.virtualWrite(VIRTUAL_CHANNEL_9, BAT_1); //Батарея кухня
Cayenne.virtualWrite(VIRTUAL_CHANNEL_10, BAT_2); //Батарея спальня
Cayenne.virtualWrite(VIRTUAL_CHANNEL_11, BAT_3); //Батарея гостиная
Cayenne.virtualWrite(VIRTUAL_CHANNEL_12, BAT_4); //Батарея детская
}

Also have a look at Data types for Cayenne MQTT API for humidity and battery data types.

And this data will go away at once?

yes.
