+
+The TMP117 is a high precision temperature sensor that communicates over I2C. Each sensor is tested on a NIST tracable test setup during Texas Instruments' production process. Accuracy should be at worst 0.1C across the -20C to +50C temperature range.
+
+To use the sensor, first set up an :ref:`I²C Bus <i2c>` and connect the sensor to the specified pins.
+
+If accuracy is a must, see section 8.2.2.2 of the `datasheet <https://www.ti.com/lit/ds/symlink/tmp117.pdf>`__.
+
+.. code-block:: yaml
+
+    # Example configuration entry
+    sensor:
+      - platform: tmp117
+        name: "Living Room Temperature"
+        update_interval: 60s
+
+Configuration variables
+-----------------------
+
+- **name** (**Required**, string): The name for the temperature sensor.
+- **id** (*Optional*, :ref:`config-id`): Set the ID of this sensor for lambdas/multiple sensors.
+- **address** (*Optional*, int): The I²C address of the sensor.
+  See :ref:`I²C Addresses <tmp117_i2c_addresses>` for more information.
+- **update_interval** (*Optional*, :ref:`config-time`): The interval to check the sensor. Defaults to ``60s``.  The sensor component sets the maximum possible averaging in the sensor based on this.
+
+.. _tmp117_i2c_addresses:
+
+I²C Addresses
+-------------
+
+In order to allow multiple sensors to be connected to the same I²C bus,
+the creators of this sensor hardware have included some options to
+change the i²c address.
+
+-  If the address pin is pulled to GND, the address is ``0x48`` (Default).
+-  If the address pin is pulled to VCC, the address is ``0x49``.
+-  If the address pin is tied to SDA, the address is ``0x4A``.
+-  If the address pin is tied to SCL, the address is ``0x4B``.
