About this item

Product details

One of the most straightforward and informative home weather stations you can buy, this AcuRite weather station (01121M) acts as an indoor/outdoor thermometer, an indoor/outdoor hygrometer, and a weather clock that automatically adjusts for daylight saving time! As mentioned, the included atomic clock provides split-second accuracy, so if you have a programmable alarm set on the display, you’ll always know exactly when the temperature or humidity has met or exceeded your customizable minimum or maximum value! The indoor weather station is AC-powered and can take three (3) AAA alkaline batteries (not included) for optional battery backup in case of a power outage. The wireless outdoor sensor requires two (2) AA batteries (not included, lithium recommended for optimal performance). This weather station weighs 1.47 lbs and comes with a one-year limited warranty.

Works great after needing to be "hard reset"

Works great once I registered it with Acurite and emailed them for some troubleshooting issues. The whole piece locked up after about 45min. Ended up having to "hard reset" it per Acurite instructions, which I'm surmising may have been a consequence of the shipping. Either way once I followed their directions to "hard reset" it. The piece works great and I absolutely would recommend it to a friend

I recommend this unit.

Great display. It had all the information I wanted. Pretty easy to set up. Had to use the manual mode for the pressure reading, but that all depends on the altitude where you live.if you want it to be accurate. No Problems at all. Install with the sensor. The proper batteries for your temperature conditions, put it in a proper setting and you're ready to go. I'm pretty happy with it.
