DS18B20 sensors read 0 and N/A
#5
i am using a cable with three wires and the splitter from this link. http://tinycontrol.pl/tinycontrol/en/pro...r_rj11.php

sometime is showing the temperature sometime not. after a while the temperature is displayed without touching the lan controller. you can see the moment in this link : https://thingspeak.com/channels/91426 the probelm can be seen on filed no.5 when is on -50 on the controller interface is showing N/A sometime is showing 0

previously I had version 3.10 (i don't remember exactly) and I switch to 3.15 to try to fix an error with my DTH sensor (basically the same, showing 0 Celsius and 0% humidity) http://tinycontrol.pl/forum/viewtopic.php?f=5&t=5957 now is even worse. the dth sensor is inside the greenhouse and the humidity is very high. but this should not be the root cause. one of the DS sensor is outside in a small glass bottle and the is some humidity inside. can be seen as drops on the glass wall. can this be the root cause? soon I have to put my tomatoes plant in the greenhouse and I have to find a solution. power on and off is not fixing the issue. it`s showing the correct values by itself from time to time. thank a lot for you time.
