1-wire to USB converter that can use 1820s directly

["Rod Speed" <rod.speed.aaa@xxxxxxxxx>]

I want to have a number of 1-wire 1820 sensors thruout the house,
and want to minimise the cost of those so I can use them wherever
it makes sense to have one like in all the fridges and freezers etc
so I can do basic stuff like alarm on out of acceptable range etc.

The obvious way to do those physically is to use phone extension
leads with RJ11 connectors on each end. Just cut them in half
and solder a 1820 on the bare end of each half. Then just connect
them all in parallel using standard RJ11 sockets on vero etc or
in punch down blocks etc.

What I want is a fully assembled USB/1-wire converter
that can be used to interface those to the PC.

I also need at least a decent driver that can
be used from VBA from Access or Excel etc.

The stuff thats obvious on the web mostly dont use such
unpackaged sensors. Cant see any reason why its not possible tho.

It would be desirable to be able to use any standard
1-wire sensor ics too, but not absolutely essential.
