MAX31856 Thermocouple Temperature Sensor
The MAX31856 temperature sensor allows you to use your MAX31856 Thermocouple
temperature sensor (datasheet) with ESPHome.
As the communication with the MAX31856 is done using SPI, you need to have an spi bus in your configuration with both miso_pin and mosi_pin set.

cs_pin: GPIOXXConfiguration variables
- cs_pin (Required, Pin Schema): The Chip Select pin of the SPI interface.
- update_interval (Optional, Time): The interval to check the sensor. Defaults to
60s. - mains_filter (Optional, string): The mains power frequency to reject (
50 Hzor60 Hz). Defaults to60 Hz. - thermocouple_type (Optional, string): The type of thermocouple used. MAX31856 supports: B, E, J, K, N, R, S, and T. Defaults to
K. - spi_id (Optional, ID): Manually specify the ID of the SPI Component if you want to use multiple SPI buses.
- All other options from Sensor.
