Hello,

 

My colleague did that. He connected 4xDB18B20 to one 1-wire bus. He used UTP cables (lenghts are 20 - 21 meters) and he connected them in paralel.

A few days ago I installed twe DB18B20 sensors to the UBS. Also had some challenges to get it working. I used the three wire setup: gnd, TD (data, yellow on my DB18B20) and TP (power, red on sensor). On UBS blue, white and brown respectively. 

First I conncted the UBS tomy HC2. The connect the sensors and power supply again.  Wait at least 10 seconds. Then remove UBS from HC2 and then add it again. Each sensor can be assiged to room.
