[misterhouse-users] 1 wire configurations (was Re: Humidity sensors)

[Jason I. C. <jcomand@MIT.EDU>]

I read that star topologies were bad, yet it works fine for me.  I have
two runs of (mostly) cat5 with 2 or 3 sensors along each wire.  I was
planning on plugging them into two separate one wire interfaces on
different COM ports, but when I used a phone line splitter to put both
legs on the same circuit, it worked fine.  I added a third leg using
another splitter and it still works.  Maybe you will get lucky too.

I reccommend using the ibutton application with its list of detectable
sensors to debug your network.  If you have the wires reversed of one
sensor, it will take down most or all of your network until you fix it.
And here's one that caused some head-scratching- some phone cords (which I
used for extensions and splicing) flip polarity of the conductors, while
other don't!
