BME280 Temperature+Pressure+Humidity Sensor

The bme280 sensor platform allows you to use your BME280 (datasheet, Adafruit) temperature, pressure and humidity sensors with ESPHome. The sensor is used in Forced Mode where measurement is performed and then the sensor returns to sleep mode until next measurement. The I²C is required to be set up in your configuration for this sensor to work.

BME280 Temperature, Pressure & Humidity Sensor.

# Example configuration entry
sensor:
  - platform: bme280
    temperature:
      name: "BME280 Temperature"
      oversampling: 16x
    pressure:
      name: "BME280 Pressure"
    humidity:
      name: "BME280 Humidity"
    address: 0x77
    update_interval: 60s

Configuration variables:

  • temperature (Optional): The information for the temperature sensor.

    • name (Required, string): The name for the temperature sensor.

    • oversampling (Optional): The oversampling parameter for the temperature sensor. See Oversampling Options.

    • id (Optional, ID): Set the ID of this sensor for use in lambdas.

    • All other options from Sensor.

  • pressure (Optional): The information for the pressure sensor.

    • name (Required, string): The name for the pressure sensor.

    • oversampling (Optional): The oversampling parameter for the temperature sensor. See Oversampling Options.

    • id (Optional, ID): Set the ID of this sensor for use in lambdas.

    • All other options from Sensor.

  • humidity (Optional): The information for the pressure sensor.

    • name (Required, string): The name for the humidity sensor.

    • oversampling (Optional): The oversampling parameter for the temperature sensor. See Oversampling Options.

    • id (Optional, ID): Set the ID of this sensor for use in lambdas.

    • All other options from Sensor.

  • address (Optional, int): Manually specify the I²C address of the sensor. Defaults to 0x77. Another address can be 0x76.

  • iir_filter (Optional): Set up an Infinite Impulse Response filter to increase accuracy. One of OFF, 2x, 4x, 16x. Defaults to OFF.

  • update_interval (Optional, Time): The interval to check the sensor. Defaults to 60s.

Oversampling Options

By default, the BME280 sensor measures each value 16 times when requesting a new value. You can, however, configure this amount. Possible oversampling values:

  • NONE (value is skipped)

  • 1x

  • 2x

  • 4x

  • 8x

  • 16x (default)
