First of all, you should read this

Blynk.notify has been replaced with Blynk.logEvent

i already change to Blynk.logEvent but it still didn’t send notification

You need to:

  1. Use existing or create new event in your template.
  2. Enable notifications for that event.
  3. in Blynk.logEvent use appropriate event’s id.

If all above has been done - check Blynk app’s Settings screen in case you have disabled notifications.

5

Posting your updated code would be a good starting point.
It would also be a good idea to post a screenshot showing how you’ve configured the event you’ve set-up for this, both the General and the Notifications tabs for that event.

Reading this tutorial is probably a good idea too…
