Dallas Temperature Component
============================
The ``dallas`` component allows you to use your
`DS18b20 <https://www.adafruit.com/product/374>`__
(`datasheet <https://datasheets.maximintegrated.com/en/ds/DS18B20.pdf>`__)
and similar temperature sensors.
To use your dallas sensor, first define a dallas “hub” with a pin and
id, which you will later use to create the sensors. The 1-Wire bus the
sensors are connected to should have an external pullup resistor of
about 4.7KΩ.
.. code:: yaml
# Example configuration entry
dallas:
- id: dallas_hub1
pin: 23
# Individual sensors
sensor:
- platform: dallas
dallas_id: "dallas_hub1"
address: 0x1c0000031edd2a28
name: "Livingroom Temperature"
Configuration variables:
~~~~~~~~~~~~~~~~~~~~~~~~
- **pin** (**Required**, number): The pin the sensor bus is connected
to.
- **update_interval** (*Optional*,
`time </esphomeyaml/configuration-types.html#time>`__): The interval
that the sensors should be checked. Defaults to 15 seconds.
- **id** (*Optional*,
`id </esphomeyaml/configuration-types.html#id>`__): Manually specify
the ID used for code generation.
