How to use device type specific configuration

time_start: Reply to Tuya-specific time synchronization requests: "1970" - Reply with seconds since 1970/01/01 (recommended, should stop the device from asking), "2000" - Reply with seconds since 2000/01/01 (use if the weekday is wrong with 1970), "off" - Don't reply (use if replying causes too much traffic). Default for this device: "off". The value must be one of 1970, 2000, off
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
