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
    index: 1
    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 and index is not specified.

  • index (Optional, byte): The index of the sensor. Required if there is more than one device on the bus and address is not specified. Note this index is based on the hardware addresses of the sensor and indexes will shift when during startup a sensor is not connected.

  • 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.
