Ds18b20 no signal

Friends I need help! after a clean Openhabian installation, I can’t adjust the ds18b20 temperature sensor. In the old version everything worked for me.

executed all commands.

sudo nano /boot/config.txt
edit /boot/config.txt
append: dtoverlay=w1-gpio,gpiopin=4
sudo modprobe w1-gpio && sudo modprobe w1_therm
ls /sys/bus/w1/devices

the result is

00-480000000000  00-880000000000  00-c80000000000  w1_bus_master1
