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 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!

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.

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 outdoorsCons 😕🔋 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.

When I purchased these I was looking for a sensor that would measure and track temperature of a deep freeze and a refrigerator that also used standard batteries. For those of you that are running Home Assistant, I have these connected to a bluetooth proxy and can monitor temperatures in HA.So far these have been great and are better than any other solution I've tried. I plan to try other Switchbot products as well for my setup as these operate flawlessly.

I was looking for a humidity sensor for home automation. My goal is to automatically cycle on bathroom exhaust fans when the humidity increases during showers. I'm using the Kasa by TP-Link wifi smart switches for my bathroom exhaust fans.Set up was very easy. I plugged in the mini hub and held the button down to initiate Bluetooth pairing. The app connected to the hub and I set up my wifi network. Once that was finished the hub knew I had 3 sensors and they were automatically added to my app. I then pulled the plastic tab from the batteries and the sensors booted up. Each sensor had a number sticker on it making it easy to know which sensor was being read by the app. I chose to use command strips to mount two sensors in my bathrooms. I know I will need to pull the sensor down to replace the batteries on occasion so I chose that over the included 3M double sided tape.Programming for this application was easy. First I connected my sensors to my Google Home, but that was probably not necessary. Then I loaded up IFTTT. In there I chose to use the Smartbot service as my trigger. I chose to ignore temperature and only trigger when the humidity rises above 50 percent. Important to note that I live in Colorado so 50 percent humidity would be high. The next step was to link the Kasa app to IFTTT and chose the fan I wanted to control. I chose not to let IFTTT turn the fan off. I run the fans for other reasons and didn't want the humidity to not allow those additional fan runs. I have the fans set to shut down automatically after 5 minutes.The sensors do show me temp and humidity in Google Home, so connecting the sensors to that app was beneficial, but not for my programming. Google Home would not give me the ability to use these sensors as a trigger to control the fans, which is why I went with IFTTT. I will use the third sensor in the kit as an outdoor sensor and set up IFTTT to turn on a whole house fan when the outside temp drops below the desired temp. I will likely set this up to only run when there is a difference in house and outside temp of 5 to 10 degrees or more.Overall, I was pleased with the easy setup and the fact that the sensors and hub are allowing one more piece of my home automation to function.

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.

I have tried a few Bluetooth weather devices, and this Switchbot is the cheapest and best.Physically, its advantages over similar devices are that it uses standard batteries (2xAAA, supplied) rather than a semi-randomly chosen button battery, and that it is visibly waterproof - it is a smooth white plastic box and the battery compartment lid has a seal round it. Also, the nylon hanging loop is as new after 18 months outside and is far better than a hole in the back meant to go over a hook or a nail.I was surprised, for such a cheap device, to find that it supports firmware updates, as there was a notification in the app on the first Bluetooth LE connection. It updated in a couple of minutes from 0.4 to 0.5 - an odd version number for a released product - and, as is almost always the case now, there was nothing stating what the update fixed or improved. But the facility is important. In fact, there were four firmware updates in the first three months and the current version is 0.9, although there has not been a further update for over a year. The app is also updated every few weeks, and there is the option to try out beta versions.The Bluetooth signal is evidently good, and not entirely line of sight - I can transfer data into the app from a room about 60 feet away with the device slightly hidden round a corner of the house.Caching is well implemented and only new readings are transferred unless you explicitly clear the cache from within the app; this greatly speeds up everything as the device quickly accumulates thousands of readings. When I got a new phone it took 20 minutes to transfer all the readings.Its accuracy is better than that of my old Bresser weather station, which cost several times as much but badly underestimated temperatures. Here the quoted accuracy (+ or -0.2C) is, in itself, accurate in my experience.Another Switchbot advantage, although it gets oddly low ratings in Google Play, is the app. It looks good unlike many similar apps, is simple to set up and use, and data export is easy - select a date range and readings are exported to a comma separated values file in a defined time step. Exporting a reading every minute gives a huge 1.7MB/month file, but exporting a reading every half hour amounts to 50KB/month.I can produce graphs very easily from the exported file - the big graph follows an import into Excel 2024 LTSC with no further changes and the other two graphs show what the app can display itself.The battery level remained at 100% for a long time and is 58% after 18 months so, if the app is reporting the level accurately, the (standard alkaline) batteries will probably last for longer than the two years advertised.The Switchbot is an excellent data gatherer. If it could record barometric pressure as well as temperature and humidity, it would replace everything weather-related here. I use a second (ancient) Android phone to provide a semi-permanent display.A minor issue is that the instructions state that the temperature sensor is good to -20C, but the device is recommended only to be used at 5C or greater. It has been down to -6C, with whole days below 5C, and I have noted two missed readings in over a year, which were both when the temperature was well above 0C.Most impressive was that I discovered a bug when exporting. I raised a ticket in the app; there was a comment back about three days later that it was being "escalated to senior technical staff", then after six days there was a fix available in Google Play! That speed of response is otherwise unheard of in my experience, where technical comments are often not even acknowledged.As I had two other weather stations fail during the bad weather (huge temperature and humidity fluctuations) in January 2026, I extended my "Switchbot estate" as the good build quality mentioned in the second paragraph matters ... a lot. This device was the only survivor.£15 (£11 with a coupon) is an absolute steal for something which would have cost many times that a few years ago for the same functionality and would certainly have been less robust and less easy to use.
