Thermometer Hygrometer, Bluetooth Indoor Humidity Meter for Home, Temperature Sensor with App Control, Large LCD Display, Notification Alerts, 2-Year Data Storage Export

These little thermometers are amazing. The app … is still in development, perhaps, there are some rough corners, but there’s been an upgrade this year, and now you can see temperature, relative humidity, absolute humidity, dew point, and something called vapor-pressure deficit on screen (on the app; the unit itself still only shows temp and RH). I’ve got temperature and humidity records going back over a year on the device I bought .. well, over a year ago, and these little things are so handy that I bought the two-pack to add extra rooms to my data. The units take up very little space, but are easily readable from ten feet away (assuming you have a light source; there is no backlight, so you need to be able to *see* the screen, but a backlight would be troublesome 99% of the time, so it makes sense that there isn’t one), and the battery on the one I bought over a year ago is still at about half charge. And that’s the battery it came with. For the cost, these are the best room thermometers I’ve ever owned. Also of note, this system is entirely modular: you can add as many devices and rooms as you wish, labeling and grouping them all however you want, and while these units on their own can’t do it, the company sells a hub device that you can pair with Alexa so your system can tell you temperatures (and presumably other data) when you ask. I’ve not invested in this, so I can’t tell you how well it integrates, or how easy it is to set up, or anything other than that it exists. But perhaps another reviewer can provide that information. I love these little thermometers. The data gremlin in me wishes I needed more, just so it could enjoy more data and more graphs. The app… is a little rough sometimes, but most of my difficulties, I think, stem from having *so much data* on my older unit, that it slows things down sometimes. But only for that device: the other two are little speed demons. I could wish for more customization: you can swap C or F, metric or imperial units for other things, toggle the secondary humidity graphs visible or not. I’d like to be able to reorder the graphs, change the colors maybe, little things. But everything works very well, I’ve never had a problem with the bluetooth connection, even from a few rooms away, the units themselves have done everything I could have ever wanted them to. I am 100% happy with these.

Works well , has nice size font although the device itself isnt large the font is large so you are able to view it from a distance. The switchbot app show a bunch of data and history on the room temp, humidity, dew point levels down to the minute by minute ...so can pick the best times to run a dehumidifier . works well with the switchbot hub...this will allow you to use the hub for communication between the gadgets in you switchbot system. only thing is you need to he within bluetooth range for it to upload the data from the device to the app on your mobile device.

This works really well and is a perfect size. The only issue is on me. I thought this was a two pack. Other than that, it is worth the money and tucks on to a shelf nicely.

Bought the two pack to start, with the intent of pairing the Switchbot temp sensor to our Lutron controlled fans in all of our rooms. Started with the Kitchen and Family Room, Kitchen is at the front of house with full South exposure, Family Room is at the back of house in a more shaded area. As the photos show there is a 5 degree temperature difference (68 - Kitchen, 63 Family Room, as shown in the photos). I rated accuracy 4 stars for 1 reason only. I am paranoid about accurate readings, so upon initial sensor setup, I followed the manufactures calibration steps and procedure. Once I completed the procedure, the displayed temperature was 1 degree off (used 32degrees as benchmark), like I said i'm a bit paranoid. Now in all fairness they say the accuracy is +/- .4 to .7 degrees, and both sensors were off by 1 degree, I'm sure these sensors are calibrated at the factory, but I just wanted to check for myself and see what they were actually set at. Using Switchbot products to setup automations in the native app works flawlessly, and should be the main goal. However when using multiple manufacturers for the automations, in my case Switchbot temp sensors and Lutron fan control switches, the automations still work well, however this can only be accomplished by using "If This Then That" (IFTTT), and should be considered a temporary automation, as the manufactures listed are not guaranteed to remain as a part f the IFTTT orbit. The whole Alexa thing is confusing because only voice commands for temperature work, humidity levels are not yet supported. In addition Alexa routines cannot be used because most manufacturers devices are not listed or available when creating routines. Hopefully IFTTT remains a viable, well recognized solution. The future as of now is a little unsettled as well, with the introduction of the MATTER standard, which is suppose to resolve many of the connectivity and linking/enabling issues that are currently encountered. Sounds like one of those baby steps plans, with more clarity and definition coming later this year and moving forward. Until then I'm continuing with my smart home design and implementation using reputable devices/components. Switchbot being one of them and at the top of my list!!

I bought two of these to monitor the humidity levels in my basement where I keep my acoustic guitars. The first thing I did after I set them up was to compare them in the same area and I was quite pleased to see how accurate they are. The humidity level numbers matched each other exactly at 34% and the temperature for both was 64° which is what my thermostat was set to. Now I know for sure it’s on the dry side down there in winter and I’ll need to add a humidifier. I’m sure there are more functions available if I were to download the app, but since I only need them for this one purpose I probably won’t bother.

I now have a total of six SwitchBot devices that provide temperature and humidity readings. They all work very well and the battery life seems to be close to two years. Due to the energy saving features, my wifi network controller sometimes shows these devices as off line, but they will wake up when queried. Data is sent to the hub using Bluetooth, not wifi. For a large home, you may need multiple hubs or a SwitchBot relay to ensure adequate Bluetooth range. Temperature and humidity readings seem to be well with the advertised specs. I chose this model because the display is much easier to read than the cheaper version. Now, with a glance at my mobile app or a quick question to Alexa, I know the status all around my home -- basement, attic, garage, patio, etc.

Love these products, I have tons of stuff from this brand like door lock, smart plugs, bot, hubs and temperature sensors. I love them all, they are very reliable and they always keep innovating and coming up with new products. They are very easy to setup, they looks very sleek , battery life is amazing and the feedback for each product on the app is great.

UPDATE: I am so impressed with this company and their commitment to their product and customer service. They contacted me because of my review and were very concerned that I was having an issue with the meter. They were very responsive and worked until the issue was resolved. I would not hesitate to purchase any of their products again. Ten stars to them!! I chose this because of the longer Bluetooth connectivity range. This has not been my experience with these meters. I particularly needed one that I could monitor in a greenhouse tent that is far less distant from the house than the stated distance in the description. However, it would not connect to the app from the house. I put one of the meters in a room next to the living room and it connects with no problem. I moved the one from the greenhouse and put it in a seedling tray where I have some things fermenting and it won’t connect to the Bluetooth from there either even though it is separated only by a plastic dome and is inside the house. I will keep the but am just unable to use them as intended.
