hello Blynkers
as the great Blynk team is working on many new features and widgets , and they already promise to provide the push button trigger “as set an icon on your home screen to activate an GPIO on your board” but i think this maybe will take them some time, so tried to use IFTTT to be integrated with Blynk.
also you can use IFTTT to do some Automation based on other service -IFTTT call it channels - you have and that will actuate and change the values of your hardware running Blynk .
examples will be demonstrated.
-
that can be used for many thing but here i will go for the basic tasks like click the icon to make your
D4GPIO high and that will actuate a relay that will switch on your fan or light. -
when your Mobile connect to your home WIFI the entrance light will switch on - assuming you have a MCU board connected to Blynk and has a relay that’s connected to your entrance lights.
-
please post your ideas in the comments.

XXXX your TOKEN XXXXwith your actual token andZZZwith the PIN number , for Digital PIN use DX like D1, D5 etc. and for Virtual PIN use VX like V1 ,V5 etc.
note that if you are using any variant of ESP8266 the pin number here
should match the actual GPIO number not as per the board manufacturer
numbering .
-
in Method select
PUTto WRITE a value to that PIN. -
