Timex TX5170 Indoor/Outdoor Thermometer with Indoor Hygrometer and Clock Review

The first place we used this thermometer, it worked great. We had it on a table near a north-facing window. We passed the wire out the window and attached it to the side of our building with the probe at the end sticking out a few inches from the wall. Temperatures were always accurate, checked with other thermometers inside and out. Humidity always seemed reasonably accurate.

We recently moved to a new south-facing apartment. It turns out that if either the base or the probe is in the sun, it will read higher than the ambient temperature. Maybe the reading is correct--the ambient temperature in the sun a few inches from the side of the building is higher than elsewhere--but that's not really useful for us. We're having trouble finding a way to wire the outside probe to have it in the shade.

The lesson is this: if you have a window where you can pass the wire through and have the end in the shade, this should work great. If not, get a wireless version.
