    • Smartphone OS (iOS or Android) + version
    • Blynk server or local server
    • Blynk Library version
    • Add your sketch code. :point_up:Code should be formatted as example below.

Simply paste your code between ``` If you don’t format your code, your topic can be deleted by moderators.

I guess you didn’t bother reading that?

yes this code is unreadable.
oh my headache !

Mmm if you are using a dust sensor and allways is high… maybe the sketch is telling you that something is with dust… maybe your post XD

I hope someone can answer you… but… with the things you posted… you never will get the answer that you request… i can’t talk for all of the people of this community… but at least me… i’ll never debug your code… is too large even for read it one time…and i’m not a fulltime code debugger… try to simplify your code, make the problem a group of little problems and then try to fix each one… one by one…

Is like you post the program of Apollo 13 and ask us where is the problem? if we didn’t see the film (trust me… is more easy remember the “thanks guy” film that know the history itself) we can’t answer it…
