1wire usb not working anymore

[hooker78]

Describe the issue you are experiencing

After upgrading to 3.73.9.20231130 the 1wire interface is not available anymore.

cat /sys/bus/w1/devices/28-000001de1d0d/w1_slave
gives error message:

cat: can't open '/sys/bus/w1/devices/28-000001de1d0d/w1_slave': No such file or directory

The folder w1 is not available.

Describe the behavior you expected

expected behaviour is printing out temperatures like this:

a0 00 4b 46 7f ff 10 10 53 : crc=53 YES
a0 00 4b 46 7f ff 10 10 53 t=10000

Additional information

Downgrading to 3.71.12.20231020 re-enabled the 1wire connection again.

That's correct. With development on 3.73.9.20231130, the kernel dependencies were revised and as 1wire usability was never officially part of RaspberryMatic it was disabled in the kernel to save same resources/dependencies.

Please outline your exact use-case (which device are you trying to integrate) so that we can evaluate to potentially re-enable 1wire support in some upcoming version again.

thank you for the confirmation.
I am using a DS9490R USB Dongle that connects to various 1wire temp sensors for measuring water and air temperature. The values a read out in a HM script using a system exec and then written into a systemvariable for further usage and information to display.

If this could be somehow re-enabled I would be very happy.
