1-wire plug-in appliance switch?

["simon_haslam" <simon_haslam@xxxxxxxxxxx>]

Here's a question someone might know off the top of their head... does
anyone make a 1-wire controlled plug-in appliance switch?

I'm looking for something like this Marmitek AM12U X10 plug-in
appliance/switch but for 1-wire?

I've found a little electronic project description here:

and circuit diagram here:

This is interesting as it appears to use an auxiliary 24V power supply
which you run on the 1-wire cable, which saves having to have a small PSU
just to power the relay.

However, I'd obviously sooner buy an off-the-shelf product. The controlled
load is actually a zone valve (a few W) but I'm sure I'd find other higher
current uses for such a module.
