My Blynk.LogEvent is not working

My guess is that you’ve probably exceeded the event limit for the 24 hour period, by having these function calls in your void loop as well as calling the functions every 1 second with timers (which try to execute at exactly the same time by the way, which isn’t possible on a single threaded device)…

You should read this…

This (especially the part about staggering timers)…

And re-read the tutorial I linked to earlier about using flag variables to limit events/notifications.
