// You should get Auth Token in the Blynk App.
// Go to the Project Settings (nut icon).
char auth[] = "";

    Blynk.notify("ESP8266 Alert - Temperature over 28C!");


void setup()
  // Debug console

  Blynk.begin(auth, ssid, pass);
  // You can also specify server:
  //Blynk.begin(auth, ssid, pass, "", 80);
  //Blynk.begin(auth, ssid, pass, IPAddress(192,168,1,100), 8080);

  // Send e-mail when your hardware gets connected to Blynk Server
  // Just put the recepient's "e-mail address", "Subject" and the "message body""", "Subject", "My Blynk project is online.");

What Blynk library version are you using?

Are you using your own Blynk local server, or the Blynk cloud servers?


did you mean that?

Yes. Uninstall version 1.0.0-beta-3 and install 0.6.1 instead.

You didn’t answer my local/cloud server question, but as you were unsure about where to find the library version I’ll assume that you are using the cloud servers.

You should be aware that with the cloud servers you are limited to 1 email every 5 seconds and a maximum of 100 emails per day.
Not exactly an infinite amount, but more than adequate for most people.
