@zboblamont said in Multiple Dallas Temperatuur sensors at one sensor node:

If you cannot daisy chain them because there is no sequential route between locations, use a separate pin for each data line (powered via resistor) and communicate with each line in turn.
The line here is using 3 cores in 20-30m of Cat5e cable to ensure each chip is physically sequential on the line.
When I added a further sensor location, a loop had to be spliced in to keep the line a daisy chain. It is a small house, the length is purely down to the route, and cable is cheap.

in case you can not daisy chain them because there is no sequential direction among locations, use a separate pin for each data line (powered thru resistor) and talk with each line in flip.
the road here is using three cores in 20-30m of Cat5e cable to make certain each chip is physically sequential on the road.
after I delivered a similarly sensor vicinity, a loop needed to be spliced in to preserve the road a daisy chain. it is a small residence, the period is purely down to the route, and cable is cheap.
