SwitchBot IP65 Indoor Outdoor Hygrometer Thermometer Wireless 3Packs, 394ft Bluetooth Range, Refrigerator Thermometer, Dewpoint/VPD/Absolute Humidity Sensor, 2-Year Battery Life, Free Data Storage

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.

I hang an "Outdoor Meter" from the basement ceiling. Meter comes with a loop for easy hanging. I didn't get a hub, I just use Bluetooth to see what's happening. It might be interesting to hang another outside by the north side of the building, where the sun never shines. But there are enough personal weather stations in my neighborhood on the Internet, so generating my own data would be redundant. If I had to find a complaint, it would be that I have to make my Android tablet attempt to connect to the meter a few times before there's a successful connection, before the data starts rolling in. Tapping the tablet a few times before getting a connection isn't a big deal, except that it wastes a minute each time before you realize the request failed. The SwitchBot app is real nice. I like moving graphs, and it moves swiftly as a day's readings come in. The meter will save a huge amount of data if you don't connect for a long time. When you finally connect, the graph will slide along as the meter downloads its saved data up into the app. Practically, you can check out a lot of history whenever you finally get the chance to look it over. You can zoom in to an hour's graph, or more compressed to display a day's, week's, month's, year's. You can adjust ("calibrate") the SwitchBot app so its readings match the local thermometer/hygrometer. Good enough for government work. My dehumidifier can be adjusted in digital increments of 5% each. When I changed the adjustment from 45% to 40%, the humidity in the basement dropped from an almost constant 46% to an almost constant 43%. Just goes to show you. Well, it's only been a day, maybe it'll drop a couple more points over the next couple of days. A month or two later... Replaced antique cellphone with modern, compact, Google Pixel 8 cellphone with Android 14. When I go looking for SwitchBot data on Bluetooth, the connection hooks up fast, without me having to keep trying over and over. Surprisingly, the performance is much better than the tablet with Android 12, even though I'd expect the tablet to have a bigger antenna, etc. I don't think it's a matter of Android 14 being better than 12; I think simply the radio in the phone is better. But I don't know. Anyway, it proves that the SwitchBot can react quickly, given some good hardware talking to it. 4 months old... SwitchBot reports its battery is at 98%. My math is wanting, but... If 4 months used 2%, 100% will take 200 months, about 17 years. I'll let you know. On the very nice Android 12 tablet, 1 hour of data rolls in every 2 seconds. On the Pixel 8 phone with Android 14, the data rolls in so fast, it's hard to be accurate, but it looks like the data rolls in at 2 or 3 hours of data every second, about 4 or 5 times faster than the tablet. 11 months old... SwitchBot reports battery is at 89%. I got my SwitchBot for about $8. Ever since, the price has been $15. I'd have bought another two more, but I can't bring myself to do it. Wish they would run some intermittent $8 sales... I guess it's the Supply vs. Demand curve. Micro Economics 101. They discovered their product is more popular than they expected. Well, it works good.

The meters work great and were simple to setup as was the hub. Everything is still working great! I would highly recommend.

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.

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

Da ich bereits mehrere Geräte von SwitchBot nutze, ließ sich dieses IP65 Hygrometer/Thermometer nahtlos in mein bestehendes Smart-Home integrieren. Die Einrichtung war innerhalb weniger Minuten erledigt und die Verbindung zur App funktionierte problemlos. Besonders gefällt mir die hochwertige Verarbeitung. Dank der IP65-Zertifizierung kann der Sensor sowohl im Innen- als auch im Außenbereich eingesetzt werden. Ich nutze ihn zur Überwachung der Temperatur und Luftfeuchtigkeit und die Messwerte wirken auf mich sehr präzise und werden regelmäßig aktualisiert. Laut Hersteller kommt ein Sensirion-Sensor mit hoher Messgenauigkeit zum Einsatz und die Messwerte werden in kurzen Intervallen erfasst. Die SwitchBot-App ist übersichtlich gestaltet und ermöglicht es, den Verlauf der Messwerte jederzeit einzusehen. In Kombination mit einem SwitchBot Hub lassen sich außerdem Benachrichtigungen und Automationen einrichten, was das Gerät noch vielseitiger macht. Die Batterie scheint sehr sparsam zu sein und die kompakte Bauweise ermöglicht eine flexible Platzierung. Für mich ist das Hygrometer eine sinnvolle Erweiterung meines bestehenden SwitchBot-Systems und erfüllt genau das, was ich erwartet habe. Insgesamt bin ich rundum zufrieden. Wer bereits Geräte von SwitchBot besitzt oder ein zuverlässiges Thermo-/Hygrometer für den Innen- oder Außenbereich sucht, macht hier aus meiner Sicht nichts falsch.
