Wow, this is my first introduction to Node Red ... this looks like great fun. Thanks for keeping us up to date on your project.
Happy Fathers Day to everyone.
Thanks for the great feedback. When I get my automatons more done, I will post links to them.
There is also a version of Node Red (Mobile Red $6.00) for android cell phones. I will be using an older one of mine for it's sensors. GPS, Tilt, magnetic heading.
