IP65 Indoor Outdoor Hygrometer Thermometer Wireless, 394ft Bluetooth Range, Refrigerator Thermometer, Dewpoint/VPD/Absolute Humidity Sensor, Free Data Storage Export, 2 Years Battery Life

I use these sensors to track the temperature of my basement, main level, and outdoor temperature. It's easy to use and relatively accurate from what I can tell. The Bluetooth range is very good where I can sit on my couch and connect to all of the sensors. I appreciate that these use normal AAA batteries that can be replaced instead of rechargeable batteries as I can use rechargeable AAA batteries to get the best world of rechargeable batteries that are also quickly replaceable.

I have tried a couple of brands of smart thermometers (Aqara and SensorPush) and I found these Switchbot sensors to be the best bang for the buck vs those other brands. The Aqara sensors kept randomly dropping their connection and the Aqara app was not very well polished. The SensorPush sensor and app work great, but they cost a lot more and do not sync with the Apple home app. The Switchbot sensors are easy to setup, and so far the connectivity has been 100% reliable for me (two months in) and the temperature readings seem accurate. They typically match almost perfectly with the temperature on my SensorPush sensor . The Switchbot app takes a little getting used to at first, but once you have it down it is a very data-rich and intuitive interface that I have really enjoyed using (especially over the clunky Aqara app). I use the Switchbot app to look at detailed temperature data, but I also have it synced up to Apple Home via the Switchbot Hub 2 so I can see the current temperature in the Home app. I do wish the Home app showed me the temperature history, but I don't mind using the Switchbot app for that instead. If you are a fan of the Apple Home app to control your smart home I think these temperature sensors are the best ones you can get! The temperature sensors and Hub 2 are the only Switchbot products I currently have, but based on my experience thus far I am sure they will not be the last Switchbot products that I purchase. I already plan to get more temperature sensors in the future. I highly recommend these!

Initially, I was hesitant to get these, as I really needed a bunch that would really work in different environments. After a year of use and adding about a dozen to my Hub 2s and working with Matter on Apple Home, I have to come back and just gush about how incredible these are! First: when paired with the SwitchBot App and cloud services, these things are incredibly. They store loads of data that can be viewed in the app on navigable graphs. Even better: you can just mass export the data to spreadsheets to view elsewhere. Second: the Bluetooth range is insanely good. I have some in my refrigerator and I can connect to them in my bedroom. Yes, it’s still Bluetooth so, the connection is hampered by the fridge door & bedroom door, but that it is even possible is a testament to how good these things are. I wouldn’t rely on the Bluetooth for my scenario, however, and I don’t have to: I can use the cloud services to more reliably connect. Third: Matter is excellent for these when paired with Hub 2 and my Apple Home Hub. The SwitchBot App treats both the temperature AND humidity readings of these as 1 device for Matter. Still, Apple has been able to treat the temperature and humidity sensors as distinct “devices” connected to the Hub 2…which is exactly the best case scenario (I save one of the 8 Matter Device slots that you are limited to per Hub 2, but still get 2 devices in Apple Home). Fourth: These really do work in harsher conditions. I have them in a bathroom that has regularly surpassed 70-percent relative humidity, in my freezer, and in my refrigerator.i haven’t had any issue. You can hang them via the lanyard, drop them on a shelf, stick them to a wall with the included 3M tape…I’ve eveb used command strips with them! They really are a value: especially when you get multiples. The sensors are just as good as the Meter Plus (which I also use), but without the screen, a longer Bluetooth range, smaller form factor, and higher whether resistance ratings.both are excellent for seeing trends and checking in on the climate at any point in time. The more you have, the better: I’ve been able to track micro changes in my apartment to fine-tune a dehumidifier. I went from a swampy house to one that is actually comfortable in part because of these. Highly recommend these! Hope this helps!

If you love data, these little SwitchBot sensors are basically Pokémon—you’ll want to collect them all. Setup was a breeze (Bluetooth behaved for once), and the accuracy is solid enough to make a weather station blush. 📡🌡️ The app? Not bad! Not amazing. Somewhere between “Hey, this is useful” and “Why is that button there?” But the history graph is easy to read, and the 50-foot range is chef’s kiss reliable. 📈👌 Physically, they feel sturdy… except for the battery contacts, which apparently skipped leg day. 😬 The contacts weaken over time, lose tension, and if you try to bend them back—snap! I broke 2 out of 3 trying to revive them. Accurate? Absolutely. Durable? Well… kinda. Like a tiny gym bro with brittle legs. They’re small (lipstick sized), easy to place anywhere, and the built-in history is great for watching temperature swings or judging your greenhouse microclimates. Batteries lasted maybe 4–5 months. For the price, I wish the battery contact situation was better. 💸🔋 Still—if you want reliable environmental data and don’t mind treating the battery tabs like they’re made of spun sugar, these are awesome little gadgets. Pros 😄 😊 Very accurate readings 📱 Easy setup, Bluetooth works instantly 📈 Helpful history graphs in the app 📡 Excellent 50 ft range 📊 Great for tracking trends indoors or outdoors Cons 😕 🔋 Battery contacts lose tension, break easily 💰 Pricey for a 3-pack 📱 App could be more intuitive

I grow photoperiod plants and can't go into garden at night to check readings of thermometer and hygrometer during dark hours. This little device allows me to accurately adjust the space heater to save some watts and still avoid dewpoint with confidence. The electricity I save will pay for this probe in no time. Not having to reference a dewpoint or VPD chart is a bonus. I like that I can export the data. I'll link that file to a spreadsheet and automate the generation of graphs, min/max data, etc... The app is okay. It works well enough. You can adjust scope of displayed line graphs for daily and larger, but not for hourly. The text is really small and hard to read in spots. It has a ton of advertising and marketing that you can avoid, but i'm not a fan of it having a "shop" feature. It's intrusive and unecessary. thankfully it isn't prevalent in the 'home' screen and you can avoid see it, but it's still there wasting space and resources turning my device into a gd billboard for commercials... that's ridiculous. Outside of the intrusive marketing nonsense, I'm glad I bought this product. Purposefully hamstringing wifi connectivity so that you have to buy their hub is contrived and lame, though. Some business practices are a bit sketchy it seems. Update: They just erased my last update.. They have designed this product to be annoying by design. It cannot even do a simpe file export to my desktop nor write the exported file to the phone's memory. Instead you have to log into 3rd party site in order to get a ling to MY file? Why am i even connecting to any location on the internet when i do not need to? This is ridiculous. They blamed this on the android phone, as if they don't write their app and have no control over how THEIR app works. If i wasn'at technologically inclined, i may have believed their poor excuse. Also, this junk needs the hub for certain functions, which again is totally unecessary. you can see other products work directly from the app on the phone. This is a choice by the manufacturer. A choice to make you more likely to log into some nonsense 3rd party site to collect info and allow access to my file.. it's not 'their' file. There is no reason for them to write an app that functions this way unless by design or simply incompetent. Overall, a lot of shady behaviour here.. unnecessary hoops that probably benefit them or their partners in some way or simply not good at writing a companion app. Flip a coin.

Wish I had found these sooner! I needed hygrometers for my fowl incubators. I’ve purchased many different brands from here and also one I borrowed from the Quality dept at Asurion. None are reliable after a few days; although it did take a week for the industrial one to go berserk. Then I finally found these by Switchbot. OMG! It’s like night and day. Finally, I have hygrometers that I can actually depend on even after a few days of running at higher heat, they don’t heat up themselves and give false, insanely high or ridiculously low readings. They give correct, stable temp readings every day. The only reason I discovered that the other brands grow incorrect over time is that I had multiple brands in my incubators. Some would go sky high and some would go insanely low all at the same time. Setting Sid by side, the temp can’t be 103 and 89 degrees and 40% and 70% humidity at the same place and time. Unfortunately, I discovered this a little late and lost an expensive batch of duck eggs due to depending on flaky hygrometers, turned up the heat and fried my duck eggs. Then I found Switchbot hygrometers and was able to get accurate readings through my next batch of duck eggs and had a 100% hatch rate. Also, they are small, short, and lie flat and low and actually get readings at egg level which is very important. They also don’t take up tons of room which is great for small incubators that don’t have much room for hygrometers. These are by far the BEST hygrometers out there that I have found. They are pricey; thus the reason I was so late in trying them, but I would have saved a ton of money on hygrometers and eggs if I’d just bought these to begin with. I am ecstatic that I found these hygrometers.

Very easy to use and install. In my uses, I have found them to be very accurate and durable. Some of the places I have used them: - Permanently inside my fridge/ freezer -Attic / Front Porch / Garage - Containers that I store my garden plants in during winter to protect plants

SwitchBot’s hygrometer/thermometers are simply great. Very easy to use, frustration-free packaging, interface immediately into SwitchBot’s very well written app. I absolutely love being able to get current temp and humidity in the house, outside, and in my fridge (on my beer shelf, to be precise). They connected right up and haven’t disconnected from my network once in the 2.5 months they’ve been here. I have these connected through a SwitchBot “Hub Mini,” which was purchased in a bundled pack with three SwitchBot Blind Tilts (another great device, by the way). I believe you’ll need either the Hub Mini or SwitchBot’s “Hub 2.” The Hub Mini works just fine — there’s no need as far as these sensors are concerned to spring for the more expensive Hub 2. The Hub 2 is a more capable Matter-certified hub, but if buying one just for these sensors, the Hub Mini gets the job done. Purchased as a three-pack, these little sensors come in at just over 10 bucks per. If you’re a data junkie, that’s a great deal for what you’ll get out of these. REGARDING ACCURACY I’ve read reviews whenging about their accuracy. When these arrived, I connected them to my network and set them all together outside on a table in the shade. After a couple hours, they all reported the same temps and humidity — within a couple tenths, anyway. Certainly within an acceptable range for me. I mean, look, I’m not doing rocket surgery, I just want to know the temp and RH. Concise calibration instructions are included in the app and they’re easy to execute. There’s no reason anyone should be complaining about accuracy. I’m posting a second video demonstrating calibration of the sensors if you’re interested. Order you some and get your monitoring on.

Używam czujników od dwóch lat i mogę jasno stwierdzić, że to świetne gadżety, działają bezproblemowo i do tej pory nie wymieniłem baterii ani razu. Leżą na zewnątrz i wewnątrz lodówki, zapewniając mi stały, wyraźny obraz temperatury i poziomu wilgotności. Pomiar jest precyzyjny i niezawodny. Polecam te produkty.

Returned. Bluetooth range not working for greenhouse location.

De thermometers zijn mooi afgewerkt en niet groot. Het batterijdeksel is afgewerkt met een rubber dichting. Werkt op 1 AAA batterij (meegeleverd). De app is handig en een mooi overzicht van meerdere weken. Verbinding is via bluetooth rechtstreeks in de app of via een Relais (apart aan te kopen) via wifi. Ik kocht een 3 pack zonder display en ben er heel tevreden over.

spritzenlösung für die drahtlose & outdoor-fähige überwachung von luftfeuchte- und temperaturwerten! batterien halten ewig & drei tage, ich hab die teile in meinem indoor-growspace hängen und nach bald 2 jahren ist der ladestand der beinhalteten (!!)1,5V AAA-Batterien immer noch >90%! ausserdem sind die gemessenen werte sehr verlässlich, untereinander ist die abweichung der messwerte <= 0.1°C/0.5% rlf .. daher von meiner seite her eine absolute empfehlung und das zuckerl obendrauf ist die super-unstressige integration ins homeassistant-ökosystem; historische und damit einfach plottbare datenreihen sind mit den bt-hygro/-thermometern ein kinderspiel und ich kann diese dinger jedem mit halbwegs technischem sachverstand uneingeschränkt weiterempfehlen :-)

Voici quelques semaines que je l'ai installée sans problème. Il fait parfaitement son job, facile à utiliser.
