V1 cannot be activated without passing the D1-D4 button

Why if i want to activate V1 ON (All The Light On), before you have to D1 D2 D3 and D4 ON first? because if you want V1 ON we have to activate D1-D4 ON first … I use relay 4 ch 5V with Nodemcu
what’s wrong?

Thank you

I have read and reread this many times… I don’t understand your issue… You seem to be saying if you want to turn the pins ON, they have to be ON first?? That doesn’t make sense.

because it really was a problem in me, because if i want to activate the PIN V1 i must pass the D1-D4 ON first

Aside from GPIO0 (D3) which has a built in pull-up resistor and thus should probably be avoided for your relay purposes. This should work as desired…

Blynk button ON = digital pins ON

Blynk button OFF = digital pins OFF.

What is your exact issue?

PS, it is better to use the GPIO numbering in your code, not the Dx silkscreened designations… and to use the green pins (below) first before others…

PPS, If your relays are Active LOW (AKA relay turns ON when sent a LOW signal), then you should reverse the button action on either your Widget settings or in the code.
