Since my hardware setup uses a CM15 with a modified antenna in the attic for RF, I pretty much have to utilize that or move to a different setup/hardware. It looks like HA can connect with X10 only through the CM11 and CM17. That link looked to me as though the HASS was communicating through RFXTRX device to the CM17 or CM11 via RF. Maybe I'm wrong though as there was a lot of technical stuff I didn't read in the post. They also suggested at one point using HeyU to connect the two...sheesh, talk about complicated!
