Opes Wireless Weather Station and Sensor for Indoor/Outdoor Temperature, Humidity, Pressure, Sunrise and Sunset Times and Moon Phase

Absolutely brilliant little gadget, that is far better than more expensive models! I originally ordered one that was £38, thinking that the more expensive it was, the better it was, but it was junk. I got this one instead which was £13 cheaper, it does everything I need it to (plus some things I don't). The outdoor sensor works well (distance 30M), it states it can work up to max of 100M but I can't comment on that particularly as I haven't tried. I needed to re-insert both sets of batteries (unit & sensor) a couple of times before they "woke up" to one another, and I would also recommend that you stand the sensor up (would be easier if the sensor had a stand too, like the main unit), but it does fine on a flat stable surface like shelving in the greenhouse, etc. Setting up is a piece of cake (not sure why so many complained it was hard?), plus you get a radio transmitted atomic clock signal, so don't have to worry if you set the time wrong either. A very useful and accurate little piece of kit.

Bought this after my previous weather station packed up. As others have said in reviews the setup is a bit tricky, and you need to follow the instructions carefully. The unit picked up the outside sensor, and then waited for this to find the radio signal from Germany. After it had received this and we setup the latitude / longitude for sunrise/set times, we found that this time was out by an hour. I tried following the instructions in the book to temporarily set the time zone out by 1, and then override the time manually. However the following morning the time had gone back to being an hour out. So in the end we set the time zone back to UK time (+0) and the time was right, but the sunrise/set times were out by an hour. A full day later the clock these had corrected themselves, so it seems like it just needed a bit of time to receive and process the time signal for both time, and the corrections for the sunrise/set times. Now that its up and running I'm very happy, have listed as 4 stars because its fiddly to setup. Advice to UK purchasers is to be persistent, set the timezone / latitude / longitude and go do something else for 48 hours while it finishes receiving the time

This is a great product for the price. It arrived promptly. I inserted batteries (not supplied) in the main unit and the transmitter and it worked instantly, without any setup required. The clock and calendar set themselves automatically. The transmitter needs to be protected from direct rain and snow, so I have it inside an old plastic dustbin at the bottom of the garden, about 30 feet from the house. The main unit is on my kitchen window sill in a direct line of sight. I can't vouch for the accuracy of the weather readings, but they all look reasonable, so I'm very happy with this purchase.

This is a brilliant little machine which was far easier to set up than anticipated when reading the instructions. The displays are easy to understand and I just love the fact that the time is connected to the Atomic Clock so that I know exactly what time it is. Both temperatures seem to be accurate and the air pressure indicators at the bottom do help to anticipate the forthcoming weather. I have only had it for a couple of weeks but find I rely on it more and more. I haven't explored its full range of capabilities yet but feel sure they will be equally as efficient. Its a much better instrument than my previous 2 weather stations and cheap considering its sophistication.

Well the radio-controlled clock doesn't work, but then I wouldn't expect it to; I've never found one that does! The unit is VERY complicated to set up, not helped by certain instructions in the manual which are just plain wrong. It's a case of trial and error I'm afraid. There are good points: it's possible to set the pressure reading to your locality, and the temperature reading is fairly accurate, although it takes a long time for the reading to change. I'm just waiting to see if the outdoor sensor is actually waterproof; others in the past, amazingly, have not been! Only time will tell. Overall: it's cheap, and you get what you pay for!

I am very satisfied with this product. I love all the settings and the fact that you can calibrate everything on the device - including indoor & outdoor temperature and humidity , latitude, longitude, altitude and threshold settings. It is relatively accurate, give or take. If you want something super accurate, you want to look at different price point device. The outdoor sensor is showing different temperature compared to local news weather station, but when I move my car close to area where the outdoor sensor is installed, both sensors show exactly the same temperature. I live 10 km out of town and always felt the temperature given by the local news was off...even on the old device(Oregon). The weather prediction based on air pressure is accurate, predicted rain and was raining, predicted sunny and was sunny. It needs to settle for couple of days and then should show accurate results. Here many people living in UK and Ireland have problem to understand - the time zone has to be set to 0 (initially there is only time zone to be set even though the manual shows different), the time will then sync with the atomic clock based in Germany, but the sunset and sunrise will be out by 1 hour. You have to wait couple of days and the sunset and sunrise will be corrected automatically, you can see it by 2 extra icons showing in the time area. If you have problem to set correct latitude and longitude, search online for ClimeMET CM9088 manual, it is similar if not the same device. The display is not as good as on Oregon, it is harder to read if the device is higher than you eye level. If you want just to pop in the batteries and be done with it, this is not device for you!

Very disappointing. In the UK (London) the synching is a nightmare to calibrate, even after 48 hours the SUNRISE and SUNSET have not correctly set (today, it says SUNRISE 13:49 and the SUNSET will be at 03:38. Not good). But the Lat. and Lon. is correct. The time calibration is from Germany and manual adjustment has to be made, as the UK changes from GMT to BST. The layout is however is very clear and the back-light is very handy. The Instruction Manual states: Item 33 is DATE (Y/M/D) which could be confusing for UK setting as we are more used to stating Day/Month/Year). The Pressure sequence display is essential for any amateur. The outdoor sensor is a fantastic slim-line design and can be discretely placed in the North aspect. However, as the SUNRISE/SUNSET cannot be recognised automatically, this item will be returned to for a refund.

This replaced a failing weather station we've had that worked fine for several years. We chose this as the alternative based on value for money and information displayed. We wanted link to radio clock - this has this but took a long time to pick up the signal - much longer than two previous weather stations we've had. It was easy enough to adjust the time to UK from the European time the radio clock broadcasts. The other feature we liked was the sunrise and sunset times this weather station has (our last didn't have this). Out of the box it was showing back to front sunrise and sunset times even though software set to northern hemisphere. I thought changing it to southern hemisphere might fix it, it didn't but changing back to northern hemisphere had everything come right. Found our latitude and longitude readings from Google Maps, and we now have sunrise-sunset times that correlate reasonably with BBC weather app readings. The inside-outside temperatures read fine and it shows some weather prediction that we don't pay too much attention to. The instruction manual was clear enough though I think it helped that I had set up previous similar weather stations. So far, so good. How well batteries last, and longevity of item remains to be seen. So far loses a star because was fiddly to set up and took much longer than other weather stations we've had.
