Turns out I didn't need the NPN transistor or the 74HC04 chip at all.
In my wemos "station" sketch I have assigned an ledPin (D1) and triggerPin (D7) in the setup.
Assigned the led pin =LOW and triggerPin =HIGH. When the button on the Wemos AP is pressed, the station ledpin goes HIGH, the triggerPin goes LOW waits milisecond, then triggerPin =HIGH
int value = LOW;
if (request.indexOf("/LED=ON") != -1) {
digitalWrite(ledPin, HIGH);
digitalWrite(triggerPin, LOW);
delay(250);
digitalWrite(triggerPin, HIGH);
value = HIGH;
}
No inverting necessary.
