Workflow for Self-Closing Bed

After a bit more thought I have revised the 'Auto Bed' workflow into a logical sequence for coding.

It now looks like this...



In the code there will have to be smaller loops and commands.

These will include...
How long should the button be pressed for before an action happens?
How does the bed know it is open or closed? Can this be calibrated easily?
Can you stop / reverse the function mid-way with a button press (similar to a garage door)?

I am sure that there is more. There usually is.

Time to get coding (although I'll probably spend most of my time prototyping).
