Loved this indoor/outdoor thermometer. It works very well! And it’s attractive. And it was a fantastic price too!

The basic thermometer/hygrometer part is very excellent. But, the remote sensor is nearly useless as it is connected by a cable to the show. They tell you to bore a hole in the wall to take the sensor outside but the cable cannot be detached which means the hole would have to huge enough to fit the total sensor through. Anyways, who wants to make a hole in the wall to the outside .. hot/cold air would be rushing in through it.

This unit provides both temperature and relative damp readouts. You can check both inside and outside temperatures in either Fahrenheit of Celsius. The outside temperature is provided to the show through a wire attached sensor. I located the show near a window and ran the wire under the lower sash and over the exterior sill, so that it was not necessary to drill any holes.
The indoor and outdoor temperature sensors are accurate (relative to each other) surrounded by an error of about 2 degrees Fahrenheit. This was determined by leave-taking a unit inside for a day, and noting both indoor and outdoor sensor readings, with both sensors indoors measuring the same ambient temperature. The difference between them was about two degrees.
The relative damp readout of one unit, of the two I bought on sale, has stayed permanently stuck at 20% and is, thus, of no value. The second unit’s hygrometer, although not frozen, is inaccurate. I use the unit with the most accurate temperature readouts for indoor and outdoor temperature readings, which are usually surrounded by two degrees of other thermometers around the house.
The main goal motivating these buys was to get reasonably accurate relative damp readings. Owing to the failure of the two units I bought to provide adequate damp readings, and their temperature inaccuracies, the Holmes Digital Thermometer and Hygrometer is not recommended.
