Notification widget

The Notification widget allows you to send push notifications from your Raspberry Pi to your smartphone or tablet.

This has the following limitations:

• The maximum message length is 128 characters (mix of alphanumeric and symbols)
• You can send only one notification per 15 seconds

However, you can increase the message length by including the following statement at the beginning of the code:

#define BLYNK_MAX_SENDBYTES 256 // Default is 128

You can add a Notification widget onto your project canvas using the Widget Box. The Notification widget also consumes 0 units of energy from your energy bank. Only one notification widget is allowed for a project:
