Don’t share your IDs….

======

Do you have the API documentation for your library ? Does it list notify?

======

Why do you have those begin twice?

Your topic has been moved to a more suitable category. Please read the sticky topics in Uncategorized - Arduino Forum for tghe "why".

I don't use Blynk, but a quick search turned this up:

Blynk.notify has been replaced with Blynk.logEvent

ok thanks

Also if you read the Blynk documentation it states do not use delay(). Your delays total more than 3 seconds! This will stop blynk from working properly
