How to use device type specific configuration

temperature_calibration: Calibrates the temperature value (absolute offset), takes into effect on next report of device. The value must be a number.
temperature_precision: Number of digits after decimal point for temperature, takes into effect on next report of device. This option can only decrease the precision, not increase it. The value must be a number with a minimum value of 0 and with a maximum value of 3
humidity_calibration: Calibrates the humidity value (absolute offset), takes into effect on next report of device. The value must be a number.
humidity_precision: Number of digits after decimal point for humidity, takes into effect on next report of device. This option can only decrease the precision, not increase it. The value must be a number with a minimum value of 0 and with a maximum value of 3
