This is the Climate Addon:
- Measures Temperature, Humidity and Pressure
- Generates Values for: Temperature in degrees C and F, Humidity in %, Pressure in Pa, Altitude in Meter and Feet
- Required Hardware Module: Bosch BME280
- Required Hardware Module: Bosch BME280/BMP280
- Required Library: SparkFun BME280 Library v1.1.0 by Marshall Taylor
