Is the address correct?

Show the serial log for the 1-wire bus scan.

Also GPIO14 is not a good choice. It outputs PWM at boot and could confuse your sensors. See the table lower down on this page for the best GPIOs to use: https://randomnerdtutorials.com/esp32-pinout-reference-gpios/

Yes, the address is ok. i can see the sensor data on the webpage of the device. it only not shows in HA.

Please show your device serial logs.

Oh I miss configured it. That DS sensor ID was declaired in an other esphome device config so HA missed it.

Thanks for your replies
