KC868-A16S and ds18b20

[admin]

1. make sure your sensor's cable is good contact.
   
   
   

2. add 1 wire code for ESPHome, to see your DS18B20 sensor's address ID in ESPHome LOG.

Code:

one_wire:
- platform: gpio
   pin: GPIO14
   id: sensor_1

   
after download firmware, you will see the DS18B20 ID. Then use this ID add to your config yaml.
   

Code:

one_wire:
- platform: gpio
   pin: GPIO14
   id: sensor_1

sensor:
  - platform: dallas_temp
    address: 0xaa0b239c56a51b28
    name: temperature
    update_interval: 10s
