1 wire temperature monitoring

["Nigel Giddings" <nigel@xxxxxxxxxxxxxx>]

Hi,

=20

I have been looking at extending my 1-wire temperature monitoring in the
ho=
use. 1-wire was never designed for long cable lengths and begins to suffer
=
reflections if the cables get too long... well I have reached that point.

I want to monitor some of the H/W pipes to things like the showers and
bath=
s, to trigger towel rail heating and also temperatures on the heat
exchange=
r to see if it actually exchanges heat as well as a couple more room and
eq=
uipment rack probes....

However, I have run up against the cable length issue.

What I have found is a Hub that effectively separates three daisy chains
of=
sensors to enable three lengths of cable with sensors.

What is also nice about this is that it connects to the PC via Ethernet so
=
you can remotely position it wherever you have Ethernet connectivity, even
=
over the internet....

I intend to use with Homeseer with a plug-in called Ultra1wire to do all
th=
e leg work and place the data into virtual devices in Homeseer which can
th=
en be used however I want.

They are in stock, spoke with them today, and will probably order 1 on
Mond=
ay (=A399 + VAT + P&P =A37)=20

Just thought I would pass it by the list to see if any other alternatives
e=
xist....
