Extremely quick and easy to set up, this weather station consists of just connecting to a USB-C power source or inserting three AAA batteries (not included). When switched on, the settings are controlled by radio, so that the time, date and moon phase are set automatically and the outside temperature is read from the separate outdoor unit, which runs on AAA batteries. When testing the outdoor unit, there was a temperature deviation of 0.5°C compared to other monitors and when the outdoor unit was placed indoors next to the indoor unit. However, as a home user, that doesn't worry me. Features include a graphical weather display, barometric pressure (missing from several other weather stations), humidity readings, a clock, and an alarm clock. Alerts can be set during severe weather, such as a frost or excessive heat warning to protect vulnerable crops or covering a car's windshield to protect against frost. Instructions are printed on the back to remind the user of the use of the additional functions of the weather station. Because many instruction manuals are misfiled or lost, having the instructions printed on the actual product can be extremely helpful. The display is bright and clear and can be hung on the wall via the built-in stand or used on the desk. There was a power outage yesterday during a storm and within minutes of power being restored the unit reset and was running again without user intervention. We have used quite a few weather stations and this is the best of them all so far. Recommended because of its ease of use, total reliability, comprehensive range of functions and attractive appearance.
