sonofff SC Resolution

[mrmin24]

It seems that the SC always reports a round number even with a decimal. e.g. 25.0 degrees or 79.0% humidity.
Is this a HW limitation or possibly the Atmel firmware?

Different items are in play here.

• The DHT11 sensor in the Sonoff SC is the most unpleasant sensor someone would ever want! Read up it's specs and you understand why it's humidity is more like a lottery and it's temperature should have been documented as Cold, Warm or Hot. In short it's temperature resolution is but 1 centigrade and it's humidity is also but 1 hPa.
• The Atmel software does no job in providing better resolution as there just is no better resolution for such a sensor.

If you want results without resolution just change them with command tempres 0 and humres 0
