+#sensor_type:

+#i2c_address:
+#  Default is 118 (0x76).  Some BME280 sensors have an address of 119 (0x77).
+#i2c_mcu:
+#  MCU the sensor is connected to.  Default is the primary mcu.
+#i2c_bus:
+#  The I2C bus the sensor is connected to.  On some MCU platforms the default

+#i2c_speed:
+#  The I2C speed (in Hz) to use when communicating with the sensor.  Default
