Weather info wrong, outside temp off, atomic clock not working
597001
The very reason you buy this is to have atomic clock, outside temp, and weather info. It frequently tells me outside is raining when there is no rain in sight. Outside temp is inaccurate, and very slow to respond, Atomic clock show no signal. I have La Cross brand, it is much better.

Moon phase is incorrect and DLST does not adjust automatically. I can place two  outside monitors side by side and get a 3 to 4 degree  reading on second La Crosse clock.  Inside temperature also  differs.

Going to call someone on Monday!!!! Was working fine and suddenly the outdoor temp stopped working properly,showed 71 degrees at night when it was 36 or so. Took batteries out waited about 1/2 hr put recharged batteries in and worked seemingly for a few hrs and then back to 71 degrees .then it changed temps a few times but nothing close to what it actually was.right now it's blank and I have the outdoor unit sitting next to it. Have the same unit in fl. And haven't had a problem.  FRUSTRATING !!!!!!

Unit stops displaying accurate outside temps when outside drops below plus 14 degrees F.  I verified with 4 other thermometers.  It just sits at 14.0 while outside temp keeps dropping.

I like the clock overall, the time and temp projections on the ceiling are plenty big enough to see. The color is easy to see but is not too bright to be a distraction. The only issue I've found is that the temperatures may not be exactly accurate. One the first day, I placed the outdoor temp sensor right beside the clock so that both the indoor and outdoor temp should have read the same thing. However, the outside temperature was indicated as 1 degree cooler. So, I'm not exactly sure which is correct. Otherwise, I'm very happy with the clock.

Not accurate or rite. Temp off by 3 degrees. Humidity is also off. Display is easy to read.

Does not sync to radio signal and, get this, projected time is BACKWARDS!

I'm having trouble getting this to work.  We have had two other weather monitors w/o any trouble. Is it too late to return it?

Because I have another, higher-end LaCrosse weather station, I thought this would make a good replacement for an Oregon Scientific one I had been using on the second-floor.  Boy, was I wrong.  Even after three days, the atomic clock wouldn't set, and the outdoor temperature sensor, placed in exactly the same location as the Oregon Scientific one, communicated only intermittently. Most of the time, the outdoor temperature never registered.  The indoor temperature reading worked fine, but since I bought it for the atomic clock and outdoor temperature, the unit was completely useless.

If you are still considering purchasing this, check the specs for the size.  It's very small and, for that reason, not all that easy to read even when it is working.  I just ordered the&nbsp;<a data-hook="product-link-linked" class="a-link-normal" href="/Ambient-Weather-Wireless-Advanced-Weather-Station/dp/B003OSSH9G/ref=cm_cr_arp_d_rvw_txt?ie=UTF8">Ambient Weather Wireless Advanced Weather Station</a>.  My fingers are crossed that the new one actually works.

We had one exactly like the one we ordered that was destroyed in our move from one State to another.  We really liked the first one which was very accurate.  This one never has the correct temperature.  We have tried various windows with no luck.  If we hadn't thrown the box, etc. away we would have sent it in for an exchange.  It does keep the correct time, but we could find that by looking at a clock or watch.  The temperature was what we really wanted. We're disappointed since it doesn't work right.

At first glace I was extremely happy with this instrument.  It has a great display face, clear and easy to read.  I installed the batteries and proceeded to set the time and date.  Well, this worked fine until the next day when the atomic clock kicked in and stayed locked on Pacific time.  Unfortunately I live on the east coast and the "SET" button would not advance through the various time zone settings; there must be some hidden trick to get it to switch.  I finally got it to switch to EST but not EDT.  I guess I'll have to wait until the fall to see if the atomic clock picks up the time change.

The outdoor temperature never worked at all for me. I put fresh batteries in both the display unit and the transmitter, and changed them out a couple of times just in case. The transmitter flashed as it should, indicating that it was sending a signal. But either I got no temperature on the display unit or I got an obviously incorrect temperature that never varied. The unit is also unnecessarily large, which is my own fault for not researching in advance. And there is no backlight. I sent it back.

The clock works great, the inside and outside temperatures have been great and (I assume) accurate.  It did take 2-3 hours after installing batteries before it set itself to the right time.

The weather display on the middle is very fuzzy at guess what the weather is.  It does not communicate or receive the forecast from any external source, it simply decides whether the weather is "improving", "staying the same", or "getting worse", and displays the corresponding sunny, cloudy, raining icon.  I'm in Arizona, and it's funny how often it has the clouds or even raining clouds when there is rarely a cloud in the sky.  I supposed I should have researched or guessed that it probably isn't an accurate weather forecast pulled from some radio or online source.

This year it decided it wasn't going to change over to standard time in the Fall.  All our analog atomic clocks changed over but this digital one didn't.  It was showing the icon that it was synched up but no time change (and yes, the DST switch is in the correct position).  I did a 'hard reset' (changed the battery) and reset the calendar et al.  I hope it does it's thing for DST in the Spring!

The clock is silent and showing accurate time after about a week. But, I had paid a little more couz it had thermometer and hygrometer but they don't seem to work. Thermometer has been staying at 80 at all times (although the temp changes (use of AC) between 72 to 80 in our living room depending on the time of the day) and the humidity is constant at 60% all times no matter when we use AC or dehmumidefier or leaving all the windows open. So, these are more like decorations on the clock's dial w/o actual use. I wanted to return it but I had already trashed its packaging. :(

Since I received this clock, I have been trying to get the time to set correctly. At first I though I had it too close my computer, because it would not set the time correctly, so I moved it right next to a window, across the room from any electronics. For 3 days, the clock seemed to be working correctly. This morning at 7:00, I had the correct time; now at 10:15, the clock is showing 11:15. I am in Central Standard Time, but the clock has had to be set to Pacific Daylight Savings Time for it to read the correct time for me. I am very unhappy with this clock and I am going to have to get another one.

The daylight saving time controls on this device do not work correctly. As background, when US daylight savings time (DST) is in effect, NIST's WWVB atomic time standard radio transmission reports that fact, every hour on the hour, in its rather complex time code.

What's supposed to happen next: If the clock's DST control is turned on, then when WWVB says DST is in effect, the clock sets the time forward one hour. If the user has turned DST off, the clock ignores WWVB's DST code.

What actually happens: Even if the DST control is turned off, the next time a DST-is-now-in-effect code is received, the clock turns DST on. If the user turns it off again, at the next round hour the clock overrides the user setting and turns DST back on again.

We live in Arizona, which uses Mountain Standard Time (MST) but does not use DST. Because of this DST-handling flaw, our RCR-22 is wrong by one hour for about half the year. We have spent a lot of time adjusting the clock settings, resetting it to factory defaults, cold-rebooting the processor with the little paperclip switch on the underside, moving the time signal antenna around to find the best WWVB reception, etc. But nothing solves the problem. The only solution we have found is to manually change the clock's time zone to Pacific Standard Time (PST) + DST, which gives the correct Arizona time during the months of the year when DST is in effect, then manually change back to Mountain Time during the non-DST months.

We need to emphasize that this is NOT normal atomic clock behavior. Instead, it indicates either a sample defect or a design error. We have several atomic clocks in our household, from a large wall clock to a wristwatch, and except for this clock-radio and some travel clocks that are around two decades old, the others handle DST correctly.

We bought our RCR-22 in late 2013, and its software version is said to be P01. Perhaps with later software it would work correctly. But even if true, this possibility is cold comfort, because the clock's software cannot be updated.

Caveat Emptor.
