WS-10 Wireless Indoor/Outdoor 8-Channel Thermo-Hygrometer with Three Remote Sensors

UPDATE: 2025. 2 out of 3 sensors still going strong! The base unit works great but has trouble picking up the signals when the batteries get low. An easy fix. One sensor still reads correctly, but the signal is too weak for the base to pick up. Otherwise this whole unit is going strong! UPDATE 2020: After a couple seasons the sensors have developed some "issues". Whenever they are in extreme conditions, above 90s or below freezing AND/OR the batteries are low, they don't send a strong signal to register on the main unit. The sensors do work, I've checked and they show the ambient temp correctly, but the farthest units don't register a signal inside the house. If its important, use fresh batteries! UPDATE: The batteries of the main unit finally pooped out in early February 2018 almost a full year later! One of the sensors needed batteries a couple months ago, but the others are still going strong. Bought this digital weather station so I can monitor the outdoor greenhouse, the temperature on the back deck, in the garage and the ambient temperature in the house. Discovered it takes 10, AAA batteries which set me back a day or two before it finally got it set up. Out of the box, it was way off! But after 30 minutes to acclimate, it was calibrated against the ancient high quality [west] German analog technology. The digital sensors' humidity read a full 10% below what my gauge read, so that got adjusted to match inside (the humidity reading for the sensors going outdoors was not adjusted). It wasn't too hard to setup up as long as you follow the directions in order. It can even sound an alarm if the greenhouse gets too hot or too cold. The instructions say not to exposed the sensors to direct sunlight, so that took special placement in the greenhouse to keep it in the shade. So far, the sensors aren't having any problems transmitting from outside in the backyard (50 yards away), through the walls of the garage or the backdoor slider. I will update this review on how long the batteries last, or if it starts to flake out. It won't get 5 stars till its preformed well for a few months.

Quite impressed with this durable thing. Used daily to monitor conditions in our homes in two different continents over the last 9 years. Still working till this day except for minor issues like the screws for the battery lids not tightening anymore.

I bought these to monitor the temperature and humidity in my garage and unheated basement. I have plumbing in the ceiling of both and like to watch for freezing temps that could freeze my pipes. I primarily chose this unit as it tells both temperature AND humidity and displays both on one easy to read screen. I ended up putting the display in my kitchen, one sensor in the garage, the second in the basement and the third outside. Since the display unit also shows its own temp and humidity, I'm able to monitor the entire house and compare it against what's going on outside with one glance. I've already been able to put it to good use. The other day I saw humidity in the basement was getting too high and I'd normally just open the windows to dry it out. Then I noticed that the outside humidity was just as high despite it not "seeming" like a humid day so I didn't bother opening the windows as it wouldn't have helped. The next day I saw it was less humid outside and waited for the temperature outside to warm up to the same temp as the basement, then I opened the basement windows to let the drier outside air in and not worry that I was letting colder outside air in. The packaging for the set isn't impressive. It's a fairly generic box and bubble wrap, but I didn't buy it for pretty packaging so don't really care. Setup was pretty easy and despite the instructions telling you how to setup each sensor on a different channel using dip switches, I found they were already set to different channels so I didn't have to. I just popped in the batteries (not supplied) and let them sit for a half hour while they equalized. At first they were all different temperatures despite sitting next to each other. The instructions state that this is normal and to leave them alone for about 30 minutes. I did and they did end up getting to nearly the same readings within about a degree or two of each other, which is the margin of error (+/- 1 degree) for the unit. I placed one sensor in the garage which is one floor down and about 20 feet away from the display with a couple of sheetrock walls in between, another in the basement which is directly under the base and one outside about 15 feet away from the display through two walls. I didn't experience any connection issues and none of them have had any problems maintaining connection so far. You ARE able to calibrate the unit to synchronize the temperature across all of the sensors, but I'm not trying to perform scientific experiments, so give or take one degree is perfectly fine for me. My main complaint is that the slots on the back used to hang the sensor are ridiculously small and the unit doesn't come with screws that will fit them, so you'll find yourself rooting around your junk drawer or spare screw can trying to find screws with abnormally tiny heads. Overall, it's a good product that so far works as I hoped and does what it says it would. UPDATE: After 7 months it's still working just fine and I'm still happy with it and haven't had to change the batteries yet.. Update 2: Almost exactly a year later I had to change the batteries on the base station for the first time. I haven't had to change any batteries in the remote sensors yet and they're all working well.

本体はリビング、子機は２階と１階の寝室、家外の軒下にラップに巻いて吊っています。 途中、電池交換を２回しましたが、再設定の必要はありませんでした。 常に最新の温度と湿度を確認でき、我が家に無くてはならないアイテムになっています。 なお、外壁を通しての通信にまったく問題がなかったのには驚きました。

the delivery is quite slow due to the delay of canadian custom... well we all know. the item is very well built, the setup process give you a typical old school feature device feeling and need some learning curve. however once setup, it works very well and flawless. I'm very happy with the result. PS. once setup leave the sensors in the environment for an hour or two to get them to adjust themselves and reflect the most accurate reading. even manual says the signal doesn't pass through metal but in my case it work just fine.

Sensor temperatures don't agree. Need to adjust the display so each sensor reading is the same. So I don't know how accurate the readings actually are. Took a while to be delivered from the US to Australia.

Wer nicht Ergebnisse wie im Labor erwartet ist mit der Station und den dazu gehörigen Sensoren vollkommen richtig aufgehoben. Ich benötige den Artikel um mein Haus bzw. Keller usw. zu überwachen. Reicht völlig zu. Luftfeuchtigkeit und Temperatur wird mir ständig angezeigt. Installation war problemlos. Was zum Anbieter zu sagen ist, absolut zu empfehlen. Mein bestellter Artikel war beschädigt und wurde umgehend ersetzt. Die Lieferzeit aus China sollte man aber einkalkulieren. Ca. 14 Tage waren es bei mir. Aber 5 Sterne für den Service und die Abwicklung. Top

This is really useful and the remote sensors work quite far away and outside (I out that one in a small plastic bag).
