The onewire platform supports sensors which are using the One wire (1-wire) bus for communication.

Supported devices:

• DS18B20
• DS18S20
• DS1822
• DS1825
• DS28EA00 temperature sensors

There is also support for bus masters which use fuse to mount device tree.

To enable One wire sensors in your installation, add the following to your configuration.yaml file:

# Example configuration.yaml entry
sensor:
  platform: onewire
  names:
    some_id: your name
  mount_dir: "/mnt/1wire"

Configuration variables:

• names array (Optional): ID and friendly name of your sensors.
• mount_dir (Optional): Location of device tree if owfs driver used.
