Relay and virtual pin

if ( V1 == 1 )

This means nothing to Blynk… you must use Blynk functions like BLYNK_WRITE(V1) in order to respond to vPin state changes.

And it is bad form to use delay() with Blynk… use timers instead.

C++ Blynk (Legacy) - Code Examples for Basic Tasks

#12 - Timers simplified… perhaps… Some have a difficult time understanding timers… and since this is a fundamental building block of Blynk… I buried this reference in the middle of this entire topic Well anyhow… This is a “real world” timer example where i am using two timers to alternately turn ON and OFF an LED… yes, there are many ways to do this, but this example is all about timers. The first timer will run it’s assigned function 500ms (1/2 second) after boo…

A Lambda shortcut version of a non-blocking timeout timer command/function works nicely.

// Timed Lambda Function - Timeout countdown
  timer.setTimeout(500L, []() {  // Run following command(s) after 500ms
    Blynk.virtualWrite(V1,0);
  });  // END Timer Function
