Does not measure outside humidity. Also accuracy is not very good.

The thermometer constantly reads 0,5-0,7 degrees Celcius higher temperature that the three other thermometers I tested it against (including an accurate Mustek multimeter). The hygrometer is not very accurate either.
Also the outside probe always gives a different reading (more than one degree) that the inside even when they are placed side by side. So the unit can't even agree with itself !
Finally the outside probe can't read humidity but only temperature, something that is not clearly stated in the description.
