I am using a few X10 modules but am thinking of automating a few things that need wired in controls. I could put in a receptacle and plug but it would be much neater to not have to do that and increased reliability would be a plus. I haven't kept up with alternatives. What's the state of the various powerline protocols? And there are likely wifi and other rf ways of controlling power but I am not up on those. Any of those open enough to use for various HA software?
