i added the string “w1-gpio” to the dt-overlays in the device configuration page and rebooted. All seems good, but it is unclear how I can test if the 1-wire feature has been successfully added. Any help would be greatly appreciated.

Hello William, you should be able to see the kernel module listed if you run `lsmod` on the hostOS. It should be named `w1-gpio` or `w1_gpio` if I recall correctly.
