Somehow, the referenced post fails to convince me. First, it says the factory shutdown early last year and then says...
1) Home Automation: We intend to continue to supply the core components that we always have. We currently have many of these items in stock and many of the remaining items are in production. Our product line of HA products is limited for now, but the core items will remain available. Over the past 6 months, we have invested a significant amount of money to have the existing modules produced again. We fully intend to continue supporting the X10 protocol.
So it appears they've had more than 18 months to deal with this and, so far, the
core Home Automation products continue to fade away.
Also, my memory may be faulty but I recall an article from 8-10 years back by Dave Rye which indicated X-10 owned or controlled their own factory in China. Thus, it should not have come as a surprise when the factory closed.
There are a number of companies in China that are producing X-10 protocol Home Automation products for 220V. It would have seemed a simple step to work with them to produce 120V products.
I hope I'm wrong but I doubt we'll ever see these core products again.
