Re: [misterhouse-users] Thermometers and 1wire obsession.. just because.

Steve - can you tell me what sort of "network" you're using for your sensors (is it
a "star", or "bus", or...?)  Also, what sort of cable are you using?

I'm trying to run a "network" of about 10 DS18B20s and having some problems
communicating to all of the devices.  I'd like to do a multiple "star" configuration
(one line of  the interface, of course), split to 3 lines, each of which is further
split to 3 sensors (I'm using RJ45 couplers at each junction).

Thanks!
