in response to Re: 1-Wire Switch, posted by Bill

There is a 1-wire hub, which may be what you are talking about.

I don't know how they work exactly, but I suspect that they are not like transparent ethernet hubs that you can add and forget.

I get the impression that the 1-wire hubs are also addressable and must be explicitly switched between branches. This is something that my software isn't setup to do.

There's also the issue that the 1-Wire bus has a "low-impedance mode" which is used to provide additional power to sensors while temperature conversions are going on. I explicitly put my 1-wire interface into this mode when I get ALL the sensors to convert at once. I doubt that any hub/switch would be smart enought to propagate this mode automatically (if at all).

This site is all about building a cool, energy efficient house, that makes maximum use of earth sheltered design, passive solar heating and cooling, geothermal exchange energy management, and right sizing of the house for it's designated use. The home's placement is on a south-facing hillside in Deep Creek Lake, Maryland. This site describes the design process, the technologies used and the expected results. We also have a comprehensive Links Page for anyone who is also interested in designing a similar project.
