Hey there,
I have really gone through all of the threads pertaining to my issue, have read all of the documentation provided and yet cannot solve my possibly very silly mistake i am doing. This is the only comment that might have shown me i am doing something wrong, so I really hope you can help me.
I have added this bit of code to my script :
BLYNK_READ(V5) // Display Widget set to reading rate frequency
{
Blynk.virtualWrite(V5, analogRead(A0)); // Send analog pin value to display Widget at set frequency
}
I have added a gauge that is perfectly reading moisture levels when set to V5, and a set frequency (1 sec)
My Eventor conditions work perfectly as long as I am inside the app, just like you said, but I can’t for the life of me, understand what I have to do to have the conditions constantly working.
Would really appreciate any help with that

}
