Yes, I pretty much did what you described. All of my one-wire stuff goes through a set of punch down blocks to get to Cat5 wiring to the rooms. I found 1 flaky run which needed a repunch. By measuring voltages, I found one device that was just acting bizarre, so, I swapped it out. I couldn't get a solid voltage reading. After swapping out with a new DS18S20, I got a solid 5V reading. I don't have a scope. I'm just using a DVM across DQ/GND. I assume this is the proper measuring technique. On all of the temperature devices which hang off of the main/aux ports, I measure a good solid 5V. On the devices which run off the passthrough port of the HUB, I am only measuring 4.4V. Should I expect 5V here? The network is running much better now. But, I do need more runtime. This was actually a good experience. I've found ways to make my software much more resilient to errors conditions. I'm also taking this opportunity to redesign some of the things I did before.
