Any chance you can point me at exatxtly what I should purchase? Are all node MCU created equal?
What sort of wire leads should I purchase? Anything else that may be needed?
@cwwilson08 These are the ones I use
Bread board.
FTDI USB UART
Jumper Pin assortment M-M / M-F / F-F (The breadboard comes with some but these are better...
Ty sir. All ordered.

@cwwilson08 make ABSOLUTLY sure that the slider on the UART is at 3.3v If you hook it up at 5v whatever you have conected is a gonner.
@JulesT I got a new bulb in today. Got it flashed and Can get White Red and Blue. No Green...
I have tried putting PWM3 everywhere else but no go. When I flashed the bulb it was plashing green so I know the color works..... Any thoughts?
Update. I have RGBW mapped out now
Gosund RGB Bulb A19
D2 GPIO4 - PWM1 (37) White
D6 GPIO12 - PWM2 (38) Red
D7 GPIO13 - PWM4 (40) Blue
D5 GPIO14 - PWM3 (39) Green
Looks like each bulb is different 
What are the requirements of your device handler?
Yeah. Looking at the the Tuya dev thing... they've basically got an app builder - you tell it what things are on what GPIO pins, and it configures the app accordingly. Seems a bit arse-about-face, but what I do know?; )
The requirements are pretty non-existent, to be honest - As long as you can go to the console and get color and 'white ' to work, then install the device handler... and point it at the IP address of the bulb. That should do the trick.
The good thing about it, basically, is that it's up to the tasmota firmware to know how to make the bulb do it's thing 
Hopefully that'll work. If not... let me know what it's up to, and I'll try to fix it up.

Hi Damon.
No app... just a device handler. No discovery, either - so you'll have to add them by hand and then configure them.
Install the following DH:
Then add device... select the driver... and configure it. Set the DNI to something that'll end up being unique - tasmota_attic_lamp_3 or whatever
-- Jules
@JulesT It does absolutely nothing for me? I installed the handler. Added the device and configured the device. Is there something I have to do in the DH?
I have configured the ip in the device
This is the log

Did you enter your IP in the driver?
OK. It's not got the IP address for some reason.
Let me create a new device at my end, and check if my code was buggered up
-- Jules
OK. It's definately not your fault, Damon.
I moved some bits around to make it less hacky, and part of that was butchering out some more sophisticated preferences code that was unnecessary. Apparently my much simpler replacement is a load of arse
Gimme 2 mins, and I'll get a fix bodged in.
-- Jules
Hi Damon.
OK. I'm an idiot. 'ip' and 'ipAddress' aren't the same variable - who'd have thought it?
My fault - because I was bodging the driver about - the IP address was set right in the state of the device I was working on anyway.
I've re-uploaded it - fetch the changed driver from the same place, it should magically start working. If it doesn't, re-set the IP Address, and all should be well.
Sorry about that, and thanks for your patience.

Everything should be here today. I've done some reading and think I'm ready. The socket I have seems to be no way of opening without destroying it. So I am putting that A-side for now.
Hopefully can ressurect the strip and get a driver going. Then flash the other.

@JulesT Thank you!!
ok I now have it controlling the bulb. Here is the issues:
Set Color hue:97 sat:100 level:89 Bulb goes white instead of red
Set Color hue:27 sat:97 level:89 Bulb goes "yellowish white" instead of green
Set Color hue:62 sat:100 level:100 Bulb goes "blueish white" instead of blue
So Set Color isn't working for me
Setting color Temp turns my light to green no matter the setting
Set Level Does Nothing
Set Hue 30 is RED
Set Hue 50 is Pink
Set Hue 60 is Blue
So, I'm very grateful for the control of these bulbs at least I can turn them on and off again. Thank you!
Hopefully the color settings can be fixed too 
Hmmm. looks like you've got the settings wrong, then.
If you go to the console on the tasmota web interface, and type 'white 100' - what colour do you get?
Similarly, if you do 'rgbcolor' commands on the web console, do the following do what you expect:
rgbcolor ff0000 - should be red.
rgbcolor 00ff00 - should be green.
rgbcolor 0000ff - should be blue.
If those aren't right, then you've got the GPIO settings wrong.
Tasmota assumes the following, I think, from playing with it:
PWM1 - Red
PWM2 - Green
PWM3 - Blue
PWM4 - White
I'd start with - do a 'white 100' - and whatever color it is - you should set PWM4 to the GPIO pin on your current setup that corresponds to the color above. Repeat for other colours until it all makes sense.
Of course... if the console does the right thing, and the driver is wrong, then it's my fault, and I'll have to work out a way to look at it
-- Jules
@JulesT Ok so I did have my pins configured wrong. You have given the BEST explanation that I have seen on this subject. Thank you.
Now only one more issue to fix.... I cant Dim. Other than that it's ready to go.
Adjusted the code to fix dimming.
