Afternoon, I followed the latest CBPI4 Gitbook for setting up server. Everthing was going well until attempting to load the DS18b20 sensors. I have 4 setup (and tested with an arduino) on onewire using 3v3, GPIO4 and GND. For whatever reason, CBPI is unable to see any sensors. I tried re-enabling Onewire in the raspi-config and restarting CBPI, no avail. I tried to move to another GPIO pin and nothing. I don't see anything glaring in the logs using the 20 parameter and it looks to be loading onewire plugin. Just at a loss as to what to do. I followed the directions of removing the python3-RPi.GPIO as I'm using a RPI4. The installed server is Serverversion: 4.4.0 - Codename: Yeast Starter || GUIversion: 0.3.13.
Also performed some additional testing and confirmation, connecting a relay works fine and I can via data from a sensor via bus command so I know it's not a GPIO Pin issue.

Then I added a second sensor, and that is showing up also.

So I have no idea why it's not populating into the list in the hardware tab.

EDIT: I found that https://github.com/craftbeerpi/craftbeerpi4/blob/master/cbpi/extension/onewire/config.yaml is showing name as "DummySensor" instead of "OneWire". Changing this to OneWire allowed only a single sensor to show up, oddly. Numerically it's the first one, if that means anything for the array.
