BMP388 / BMP390 Temperature+Pressure Sensor
The bmp3xx sensor platform allows you to use your BMP388 or BMP390
(datasheet, BMP390 product page) temperature and pressure sensors with ESPHome.
Either I²C bus or SPI bus is required to be set up in your configuration for this sensor to work.

Over I²C
The bmp3xx_i2c component allows you to use the device over I²C interface.
# Example configuration entry for I2C connection
sensor:
  - platform: bmp3xx_i2c
    temperature:
      name: "Outside Temperature"
      oversampling: 16x
    pressure:
      name: "Outside Pressure"
    address: 0x77
    update_interval: 60sConfiguration variables
- address (Optional, int): Manually specify the I²C address of the sensor. Defaults to - 0x77. Another address can be- 0x76.
- temperature (Optional): The information for the temperature sensor. - oversampling (Optional): The oversampling parameter for the temperature sensor. See Oversampling Options. 
- All other options from Sensor. 
 
- pressure (Optional): The information for the pressure sensor. - oversampling (Optional): The oversampling parameter for the temperature sensor. See Oversampling Options. 
- All other options from Sensor. 
 
- iir_filter (Optional): Set up an Infinite Impulse Response filter to increase accuracy. One of - OFF,- 2x,- 4x,- 16x,- 32,- 64x,- 128x. Defaults to- OFF.
- update_interval (Optional, Time): The interval to check the sensor. Defaults to - 60s.
Over SPI
The bmp3xx_spi component allows you to use the device over SPI interface.
# Example configuration entry for SPI connection
sensor:
  - platform: bmp3xx_spi
    temperature:
      name: "Outside Temperature"
      oversampling: 16x
    pressure:
      name: "Outside Pressure"
    cs_pin: 13
    update_interval: 60sConfiguration variables
- cs_pin (Required, Pin Schema): The Chip Select (CS) pin. 
- temperature (Optional): The information for the temperature sensor. - oversampling (Optional): The oversampling parameter for the temperature sensor. See Oversampling Options. 
- All other options from Sensor. 
 
- pressure (Optional): The information for the pressure sensor. - oversampling (Optional): The oversampling parameter for the temperature sensor. See Oversampling Options. 
- All other options from Sensor. 
 
- iir_filter (Optional): Set up an Infinite Impulse Response filter to increase accuracy. One of - OFF,- 2x,- 4x,- 16x,- 32,- 64x,- 128x. Defaults to- OFF.
- address (Optional, int): I2C only. Manually specify the I²C address of the sensor. Defaults to - 0x77. Another address can be- 0x76.
- update_interval (Optional, Time): The interval to check the sensor. Defaults to - 60s.
Oversampling Options
By default, the BMP3xx sensor measures pressure 16 times and temperature 2 times when requesting a new value. You can, however, configure this amount. Possible oversampling values:
- NONE(value is skipped)
- 2x
- 4x
- 8x
- 16x(default)
- 32x
