The Raddy WT-2 offers a cleaner, more convenient way to monitor outdoor temperature directly from your window. Unlike traditional adhesive-mounted thermometers, the WT2 uses a magnetic attachment system that lets you remove and reinstall the unit in seconds for battery replacement or adjustments.

It also tracks barometric pressure trends to provide a local weather forecast and features a built-in frost alert to help protect plants, pipes, and other temperature-sensitive areas. With an IPX4 weather-resistant design, it delivers reliable outdoor monitoring through changing weather conditions.

Ideal for gardeners, homeowners, apartment living, RVs, and everyday indoor-outdoor temperature monitoring.

QA:
Q: Do I need to remove the adhesive every time I change the battery?
A: No. With the magnetic ring design, the thermometer detaches directly from the mount for battery replacement and easily snaps back into place afterward.

Q: Is it safe for outdoor use in the rain?
A: Yes. The WT-2 is IPX4 water-resistant and designed to withstand splashes and humid outdoor conditions.

Q: Can this thermometer predict the weather?
A: Yes. It uses an internal barometric sensor to track air pressure trends and generate a local weather forecast.
