DHT sensor is lost or failed ?
I saw that you have redundancy between void ads1115() and other void !
timer.setInterval(5000,ads1115);
failed…
your code is very poorly structured 
too many redundancies
Alexis, how could I fix it?
… I tried with the varibaili goblali but I can not make it work …
… if I exclude the display on the LCD, for how I thought it works even if it is badly written 
Alexis, so far I’ve made simpler projects with blynk, this is the first time I’ve done a more complex project …
the difficulties I am encountering is the simultaneous display of the data I send to Blynk also on LCDs
I will fix that for you soon, if you can wait till tomorrow
I have to edit your code and manage it
Alexis, of course I’m waiting!
thank you so much…
I hope to learn a lot from your directions …

Salvatore,
Learn that and try it
As you can see, I managed all your sketch
I can’t test it because I’ve no ADS1015,
but , code compiles without any error on my IDE.
waiting for your comments

Alexis, thank you so much!
Your code works, do not disconnect from Blynk and display the data on the LCD, I have only readjusted the intervals of the various functions.
I think the main mistake I made was to keep the LCD display separate from the various functions. I have to understand better the functioning of the Timer which is still unclear to me.
I found that once the cycle is over, the DHT sensor data is lost (I am attaching screenshots of the serial monitor), which are restored shortly thereafter.
thank you so much.
