Hello Tomasz. The unit and valid ranges are published in the control form. See ยง3.3.1 in XEP-0325 for examples. Reasons for not using units in the actual set operation is because unit conversion is assumed too complex for the device, and that set operations follow limits defined for the parameter by the control form.

You need to know up front what unit does the control expect. There's a room for misinterpretation and mistakes like ie. frying/freezing your plants. When you specify the unit, at least you give a chance to err-out on unhandled unit if the control is unable to convert. -- Tomasz Sterna @ http://abadcafe.pl/ @ http://www.xiaoka.com/
