+MAX31856 Thermocouple Temperature Sensor
+========================================
+
+.. seo::
+    :description: Instructions for setting up MAX31856 Thermocouple temperature sensors.
+    :image: max31865.png
+
+The ``MAX31856`` temperature sensor allows you to use your MAX31856 Thermocouple
+temperature sensor (`datasheet <https://datasheets.maximintegrated.com/en/ds/MAX31856.pdf>`__) with ESPHome

+
+.. _Adafruit: https://www.adafruit.com/product/3263
+
+As the communication with the MAX31856 is done using SPI, you need
+to have an :ref:`spi bus <spi>` in your configuration with both **miso_pin** and **mosi_pin** set.
+
+- ``VIN`` connects to 5V (``3V3`` will output 3.3V), or directly connect ``3V3`` to 3.3V
+- ``3Vo`` is not used by ESPHome
+- ``GND`` connects to ground
+- ``CLK`` connects to the SPI **clk_pin**
+- ``SDO`` connects to the SPI **miso_pin**
+- ``SDI`` connects to the SPI **mosi_pin**
+- ``CS`` connects to a free GPIO pin
+- ``FLT`` is not used by ESPHome
+- ``DRDY`` is not used by ESPHome
+
+.. code:: yaml
+
+    # Example configuration entry
+    spi:
+      clk_pin: GPIO18
+      miso_pin: GPIO19
+      mosi_pin: GPIO23
+
+    sensor:
+      - platform: MAX31856
+        name: "BBQ Temperature"
+        icon: "mdi:hamburger"
+        cs_pin: GPIO17
+
+Configuration variables:
+------------------------
+
+- **name** (**Required**, string): The name for the temperature sensor.
+- **cs_pin** (**Required**, :ref:`Pin Schema <config-pin_schema>`): The Chip Select pin of the SPI interface.
+- **update_interval** (*Optional*, :ref:`config-time`): The interval to check the sensor. Defaults to ``60s``.
+- **mains_filter** (*Optional*, string): The mains power frequency to reject (``50 Hz`` or ``60 Hz``). Defaults to ``60 Hz``.
+- **spi_id** (*Optional*, :ref:`config-id`): Manually specify the ID of the :ref:`SPI Component <spi>` if you want to use multiple SPI buses.
+- **id** (*Optional*, :ref:`config-id`): Manually specify the ID used for code generation.
+- All other options from :ref:`Sensor <config-sensor>`.
