It contains, above 1-wire components, also a barometer, hygrometer and illuminance sensors. This onewire platform can read and present values from that device, but the sensors will default to disabled <sup>[4](#note_4)</sup>.

## Interfacing with the 1-wire bus
The 1-Wire bus can be connected directly to the IO pins of Raspberry Pi or by using a dedicated interface adapter, for example

### Entities and attributes
Upon startup of the platform, the 1-wire bus is searched for available 1-wire devices. For each device that this platform handles (see list of supported devices above), the platform adds one sensor for each physical quantity it measures. The name of the sensor is the device ID with the physical quantity it measures appended.
Upon startup of the platform, the 1-wire bus is searched for available 1-wire devices. On Bridge devices, the `aux` and `main` branches are recursively searched. For each device that this platform handles (see list of supported devices above), the platform adds one sensor for each physical quantity it measures. The name of the sensor is the device ID with the physical quantity it measures appended. Unsupported sensors are noted with a warning message in the log.
