Thanks for the reply. This matches my findings. My question is more basic though, I will have a single, long cat 5e/6 cable running all the way from the emonPi breakout board, past the point I want to take the first set of measurements and on to the hot water cylinder. How do I physically connect the sensors to the twisted pair in use? Presumably I’ll need to cut it then reconnect it with the sensor stub wires also in. Will any wire connectors do? The sensors are using a 1m cable, as supplied by OEM). Presumably this is the correct layout?
This is just the link I read the doc on, from your post in 1-Wire Design Guide. The link you’ve updated to works so that’s all good. Thanks!
