MAX31888 Temperature Sensor

The max31888 sensor platform allows you to use the Analog Devices MAX31888 (datasheet) 1-Wire temperature sensor with ESPHome. A 1-Wire bus is required to be set up in your configuration for this sensor to work.

# Example configuration entries
sensor:
  # only one device
  - platform: max31888
    name: Temperature
  # specific address
  - platform: max31888
    address: 0x1C0000031EDD2A54
    name: Temperature 2

Configuration Variables

• address (Optional, int): The address of the sensor. Required if there is more than one device on the bus and index is not specified.
• index (Optional, byte): The index (0-based) of the sensor. Required if there is more than one device on the bus and address is not specified. Note this index is based on the hardware addresses of the sensors and the order can change if sensors are changed, added, or removed.
• update_interval (Optional, Time): The interval that the sensor should be checked. Defaults to 60s.
• one_wire_id (Optional, One Wire): The ID of the 1-Wire bus to use. Required if there is more than one bus.
• All other options from Sensor.
