Using a BME280 with the following configuration is not able to retrieve the humidity.

i2c:
  sda: 21
  scl: 22
  scan: False

sensor:
  - platform: bme280
    temperature:
      name: "Temperature"
      oversampling: 16x
    pressure:
      name: "Pressure"
    humidity:
      name: "Humidity"
    address: 0x76
    update_interval: 15s

Debug:

Sorry, I have only one of those sensors at hand at the moment.

Hmmm, that's no good :(

I will receive my own BME280 in 2-3 weeks and I will try to debug the issue then. In the meantime and if you have time, could you enable very_verbose logs? They show all the i2c data communicated and are amazing at diagnosing issues. Thanks!

With a different sensor it works fine.

As a reference, the extended log:
