Raspberry Pi Forums

After running dmesg command I do recieve a lot lines all telling the same.
I don't understand the message. Can somebody help?

Thanks.
Strange because I'm not using W1 at this moment

If the w1 driver is loaded but no devices are connected, it will pick up phantom devices, which is what you are seeing.

Comment out the "dtoverlay=w1-gpio" line in /boot/config.txt, disable it using raspi-config or remove it from your /etc/modules (if present).
