Hello,
I have worked on Blynk App with ESP8266 using Arduino IDE.
I can convert this wifi code with Blynk App codes for ESP8266 to Open and Close the door.
Please reconfirm do you want to only and close the door via Blynk App?
I will provide the codes and also app you to setup Blynk app on your Mobile phone for this project.
I can not work on USD2/hr, You can hire me at fix price. That will be easy for both of us.
Thanks,
Sonia
