Dallas Temperature Sensor

The dallas_temp component allows you to use DS18B20 (datasheet) and similar 1-Wire temperature sensors. A 1-Wire bus is required to be set up in your configuration for this sensor to work.

# Example configuration entry
sensor:
  - platform: dallas_temp
    address: 0x1234567812345628
    name: temperature
    update_interval: 120s

Configuration variables:

  • address (Optional, int): The address of the sensor. Required if there is more than one device on the bus.

  • resolution (Optional, int): An optional resolution from 9 to 12. Higher means more accurate. Defaults to the maximum for most Dallas temperature sensors: 12.

  • update_interval (Optional, Time): The interval that the sensors should be checked. Defaults to 60 seconds.

  • one_wire_id (Optional, 1-Wire Bus): The ID of the 1-Wire bus to use. Required if there is more than one bus.

  • All other options from Sensor.
