X10 - Does SmartThings work with it?

I’m pretty sure that SmartThings doesn’t work with X10, at least not natively, but just wondering if anyone can confirm that.

OK - I’ll do it.
My plan is to use a ThingShield as a bridge to x-10.

Doesn’t do it actively / not a supported protocol.
Shield theoretically would work. Do a search, I posted the hacks necessary to build the interface cable and other info.

Let me be more direct in answering your question.
It does not support x-10.
It was never advertised or promoted as being able to support x-10.
If you are a maker/engineer, you can hack the system to enable limited x-10 functionality.
