I have 4 of this sensor https://www.amazon.com/gp/product/B00CHEZ250/ref=oh_aui_detailpage_o06_s00?ie=UTF8&psc=1 wired in parallel using pwm cables. At the omega It is connected with pin 19, 3.3v, and a 4.7k like said to do here https://wiki.onion.io/Tutorials/Reading-1Wire-Sensor-Data
This is part of my ac thermostat that I've been working on, so there is a relay shield and an oled also connected to omega 2+. It was working fine for quite a while, then the sensors were no longer listed in w1_bus_master. The only thing that I found to make them show back up is to run the code on the 1 wire sensor tutorial and reboot. Sometimes they show back up and sometimes they do not. When they do show back up, they might stay for a few hours but sometimes only a couple minutes.
I'm out of ideas as to cause and solution.
