I guess it would be nice to have some feature within Blynk App to Add alert based on certain condition/values.
For example I want to monitor my Garage Door or may be sump pump water level.
From ESP8266 I can send the numeric value of garage door ( using HC-SR04 sensor).
Within Blynk App, I shall be able to set the alert like
Display Open if V5<1
else Display Close.
Similarly for Sump Pump water level
if water level is above certain number it will display alert in the app
Also able to set push notification/email based on certain value within Blynk App.
