The frustrating thing is, you read other post (thousands) about the simple topic of using a virtual pin just to show the LED status of a digital or analog pin. Millions of examples !!! I can’t get one to work.
Do you load WidgetLED? What’s with the led1? Is that a generic reference meaning substitute the GPIO pin #? Do you load it within the Void Setup() or after? Are you supposed to put something after Void Loop() so it knows to keep your LED up to date? … I read that somewhere. If you load it in Void Setup() won’t it run once then go stale?
I read that someone was making a guide on Github for GetData, read that, didn’t cure my defective code.
I’m a Dad, four kids, they all drive. I just want to know if the Garage Door is closed or open, when did it open or close, with a history log. Glance at my phone to see the “Clsd” or “Open” LEDs glow. 
I know this is vhymanskyy’s most loathed topic YAGDO. If someone could peak into my super simple, cobbled together code and and throw me a bone I’d be grateful. I’ve got two Hall Sensors that work great. They light up an RBG (Red, Green) LED on my Breadboard (D2,D3) so I know what’s working on what’s not. The relay’s, simple as they are work great through Blynk. I’d rather key off the Hall GPIOs on the Analog side A3, A4 to free up the two digital pins once it’s mounted in the garage. I’ll take whatever works.
Thanks in advance !!!

. You will be surprised but even docs I’'m pointing to appeared only few months ago. And of course you are very welcome to make any proposals and even contribute.
