I have some X10 devices in my home, which I would like to keep using in my Raspberry Pi based OpenHAB system. My old X10 controller has packed up, so I need an interface from RPi directly to power line, and the necessary software so that I can control the X10 devices from OH. What is the best way to do this?
Given that you talk about power line communications you need to look for some kind of adapter anyway. Probably easiest to get will be USB/serial adapter. Then from one side you will have high voltage and on another you can host low voltage devices such as raspberry running openhab.
I don’t know much about X10, but there are already two ways for openHAB to communicate with it:
