hi All -
Joe -
Doug is hosting a version of my library (based on Tom's and Brohogan's code) at
We're discussing more permanent hosting options, but for now, this version is stable on the current Arduino version.
Despite much investment in time and materials, whole house couplers, repeater/amplifiers, I was never able to make the original X10 reliable (enough) in my house and have set it aside. My opinion is that it's era is over. If/when I reengage it will be with a more modern standard. I'm impressed you've made it reliable!
