I thought I would post some pics to maybe help, forgive my soldering I was trying to be as fast as possible while dealing with a toddler

Basically at the bottom you remove 5 rubber stoppers to expose tri-wing screws (ughhh!). I found the best way to take them out was take a smaller flathead screwdriver and just JAM IT IN really good and keep constant pressure and twist, once cracked you dont need as much pressure. They also sell tri-wing screwdrivers on amazon but I didn’t want to wait!

And then on the ‘underside’ you solder on (from left to right of my image)
VCC (3.3), Ground, RX, TX leads (labels visible from the ‘top side’)

and on the top side you solder GPIO0 (I00) and run that to ground (i ran it to an extra ground on my FTDI).

flipside

Then you hook that up to your FTDI (RX, TX reversed) and flash.

My YAML below, for my use case I wanted the button to activate one of the relays only, and I wanted the LED light to be assigned to that specific relay so thats the YAML below. Easily editable to require both relays off to turn off the LED etc, but only one relay on to switch the LED on. Very easily editable to also make the LED light a simple switch and not dependent on relay status etc…
