Bosch BME680 on RaspberryPi2 running Hass.io

I try to connect a Bosch BME680 to my RaspberryPi 2B running the latest Hass.io OS
I added it to my config.yaml and checked the i2c Address of my Sensor in Raspbian. It is 0x76, wich i noted in my config.yaml It looks like this:

sensor:
  - platform: bme680
    name: BME680 Sensor
    i2c_bus: 1
    i2c_address: 0x76
    monitored_conditions:
      - temperature
      - humidity
      - pressure
      - gas
      - airquality

but my Sensor is not working. In my log file it says:

2019-02-01 02:41:01 ERROR (SyncWorker_7) [homeassistant.components.sensor.bme680] BME680 sensor not detected at 0x76

I don’t know what could possibly be the problem. as far as i understand, this is supposed to be working fine. Thanks in advance for any advice.
