Has anyone run into limits of how many temperature sensors or how long a wire run they can have with one wire ?
Things are starting to get kind of flaky here with 5 or so sensors with maybe 50 feet of wire (guess).
I am using cat 5 wire and have maybe 6 (guess) one to two splitters in the system.
Not all sensors are consistently seen.
A related question, in the 1-wire tab, will selecting 'restart' enumerate the attached devices? I have seen inconsistent behaviour but am not sure if it's the sensor system or if I am not using OpenPlotter correctly.
Has anyone used a dedicated one-wire interface rather than the bit bang approach that the pi uses to get 1-wire data ? The dedicated one-wire interfaces are more sophisticated and allow for longer/bigger one wire setups.
