Ref:Again, out of curiosity, where did the need for 2 separate onewire buses arise from?
Originally I was only using one input(one onewire bus) but I was experiencing a problem where the Arduno was confusing the inputs 4 senses and was the main reason why I decided to move away from one onewire bus to 4 separate onewire buses,
even though this worked perfectly in my office as soon as I went out into the field the prom seem to come back that is the main reason why I made the change.
Okay, I see; sounds like you had protocol and/or hardware issues to begin with. 4 sensors on 1 onewire bus works just fine. I've got 3 +2 homemade devices running on a bus that is partly disconnected in some modes, works in a high electrical noise environment and overall is just challenging in terms of its boundary conditions. It works just fine...
