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 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!

I purchased this three-pack to monitor the temperature and humidity on different levels of my indoor Nepenthes growing shelf. I am currently acclimating several rare tropical pitcher plants, so having reliable readings throughout the enclosure is extremely important. The sensors are compact, durable, and easy to position almost anywhere. Each one includes a small hanging loop, as well as pieces of 3M adhesive tape for mounting. Their small size makes it easy to place them among plants without taking up much room. The Bluetooth range has been excellent. Although the sensors are located in my basement, I can check them from anywhere inside my house and have even been able to connect while standing in my backyard. The SwitchBot app also makes it easy to view each sensor separately and compare the conditions on the top, middle, and bottom shelves. I compared the readings with another thermometer/hygrometer that I already owned, and the temperature and humidity measurements were very close, which gave me confidence in their accuracy. Apple Home integration requires purchasing a compatible SwitchBot hub separately, but the sensors work very well through Bluetooth and the SwitchBot app without one. Overall, these are accurate, versatile, and very convenient little sensors. They have been perfect for monitoring my plant-growing environment, but they would also be useful in greenhouses, basements, refrigerators, storage spaces, or anywhere else where temperature and humidity matter.

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.

***1 month update: basement freezer sensor is no longer connected. I didn't get a notice that it disconnected, I just happened to notice that it was no longer reading. I even set it up to notify me for low battery sensors. I got no notifications at all but after replacing the batteries, it seems to be functioning correctly again. *** Item was packaged well and included simple instructions for setup. I noticed right off that the cords that the minihub uses are the old style USB connections and the package did not include a power adapter, which to me is absurd. If I paid for a working item but the item I received lacks the ability to even plug into a power grid, obviously I did not get a working item for the price I paid. I knocked a star for these reasons. Other than that, the item works well. It was just a bad first impression and I was lucky to have an extra adapter handy or I would have had to order and wait on that item as well before being able to use the remote thermometer I desperately needed to more accurately monitor our large tortoises' house in particularly bad weather. The items create a temp graph as they go, allowing me to see trends in the heating elements during the day and night. These are way more accurate than the brand I was using before. I threw the other two sensors into my deep freezers and now will hopefully get alarms before I get spoiled food in the event of a freezer failure. I like that I was able to integrate it easily into Google Home and can now ask the hub or my phone, "What temp is the basement freezer" or "What temp is the garage freezer" and it will instantly tell me. This was our first automated purchase and for the most part, we are very pleased with it.

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.

These have many uses and are very easy to use. The app is simple enough for casual use and lets you track trends over time for more involved users. I use them in several vegetable gardens to monitor temps and humidity levels so I can know if there are spikes when I’m not there to see. Then the obvious use of making sure the ductless heat pump is cooling/heating to the appropriate temperature. Well worth the money.

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!

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.

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.

Ik had al drie sensoren en een hub gekocht. Dat werkt super. Nu drie sensoren erbij gekoppeld. Koppelen ging heel gemakkelijk en nu heb ik in de app en heel handig overzicht van alle temperaturen van alle ruimtes op een scherm, zoek binnen als buiten! Werkt heel goed! Is inclusief batterijen, dus prijs vind ik ook redelijk.

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