Updated my review to 3 stars from 1 star after OS customer service helped me out. After the unit stopped working after 1 year, I tried several different combinations to reconnect the unit, pushing "reconnect" many times. The same thing kept happening - it would connect for a short time, then disconnect. I received the following instructions from OS, followed them, and the unit has now been working for 3 days, so I think it is worth a try if yours isn't working. Here is what OS said:
"Please try doing a battery reset, here are the steps:
A battery reset consists of a few simple, but crucial steps. (*Please Note: Keep all components within the same 10 ft. radius while re-synchronizing.)
1: Remove /batteries from indoor units and sensors. Unplug any on AC power.
2: Allow a minimum of 10 minutes for any/all capacitors to discharge.
3: Reinstall batteries into any/all sensor(s) first. Press a paper clip or pin into Reset hole in the battery compartment
4: Finally, reinstall the batteries into the main unit. Press a paper clip or pin into Reset hole in the battery compartment.
The units should re-sync immediately, however, it may take up to 10 minutes for the units to completely synchronize."
The key for me was to remove the batteries from the main unit as well as the UV sensor. So it is once again working. Overall, I still think this is overpriced, but if you have an OS weather station and want to add UV Index, this unit works ok.
First of all, this thing is quite expensive for what it does... it's a glorified light sensor. It simply detects the amount of UV light from the sun and sends the result as an integer estimate to the main console. It's also a bit odd why Oregon Scientific didn't just include this device with the weather station in the first place, instead of leaving you with missing functionality right out of the box. That being said, after setting up my weather station I soon found it to be a necessary purchase in order to complete the package. After the pain of spending more cash was aside, it was relatively easy to install the batteries and mount the UV sensor to a post using the included bracket (a ground stake is also included for placing in your yard). About every 73 seconds, according to the manual, the UV sensor takes a reading and sends it to the console.
Now for the bad. Like I have found most of Oregon Scientific's weather instruments to be, this UV sensor is not incredibly durable. After having the device for not quite one year, surviving just one mild Washington State summer and winter, the sensor failed. It simply quit sending a reading to the main unit. After a long chat with customer service, we declared it to be dead, and Oregon Scientific sent me a new one (as of three months it is still working).Read more ›

Expect this to last no more than six months. If it last longer, fantastic.
Expect pure madness in dealing with Oregon Scientific's piss-poor customer support. Read more

This is my 3rd device. They fail easy however its the only one that works with my station. If my setup and such didn't require the UV sensor i would not have one. Read morePublished on June 14, 2014 by R. Heishman
I bought this as an addition for my Oregon Scientific weather station. As soon as I powered it up and did the search on my base unit, it worked. Read morePublished on April 24, 2014 by Love Outdoors
The device only presents some reading when directly aligned with the sun. The readings shown are far below those reported by the local weather service or other handheld devices.Published on February 7, 2014 by Walter A. Blois

I own the rest of the weather station and it reports to the weather underground. It's a great addition to the station.Published on February 3, 2013 by Larry of St Louis
