Hello, I am new to the world of blynk.
The question is that I am creating an automation project and I have 2 problems with nodemcu 8266 AMICA + blynk Local server (rasberry pi):
Problem 1:
When I turn on the nodemcu the 9 relays turn ON, I can’t find a way that when the system starts they all start off in OFF.
Problem 2:
I need when I press a button1 in my blynk app through the virtual pin V1, turn on R1, R8 and R3 … when the virtual pin V1 goes to 0, R1, R8 and R3 should be turned OFF.
When I press another button2 of the APP, through the virtual pn V2 (virtual pin V2 becomes 1), turn on R2, R8 and R4.
When I turn off this button2, V2 would go to 0 and therefore R2, R8 and R4 to off.
A similar case would be for a third button3 of the APP, through virtual pin V3, being at 1 it should turn on R1, R8 and R4 .
And if V3 goes to 0 R1, R8 and R4 should turn off.
Using the button 4 of the app and the virtual pin V4, when it goes to 1, it should turn on R5 and R8.
And if V4 is 0, R5 and R8 should go OFF
With the button 5 of the app and the virtual pin V5, when it goes to 1, it should turn on R6 and R8.
And if V5 = 0, R6 and R8 should go OFF.
and this logic would not be happening and I can not find the problem or error why it does not happen
Thank you
Sorry my english
