@Dmitriy He meant the otherway… from Phone to Arduino.
@ltafuri If nothing yet available from Blynk, then you could try another app (search “send notification to Arduino” on Google Play) that sends to Arduino (usually via bluetooth) then integrate that into your Blynk system. It would obviously only work when your phone is in range of your Arduino… but then that is probably the only time you need external notifications from your phone.
Only if a new widget can tap into Arduino/iPhone notifications (email, messaging, phone ring, low battery stats etc.) then assign HIGH/LOW or even strings to a virtual pin and then out to the device for further action.
