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

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.

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!!

Take 5 minutes to integrate with my Home Assistant. Both temperature and humidity seems to be accurate. You can use the app to calibrate the temp and humidity if need in the future. My issue is Bluetooth range is very short in my home - about 100ft. Since I am using home assistant, I am ok with the short Bluetooth range. If you depend on long Bluetooth range, you might need to buy their hub which is additional 30 dollars.

Love the larger display, easy to read. Appears to be very accurate, and can be calibrated in the app. Pairs easily with the switchbot app.

It is simple and does precisely what it supposed to.

These thermometers are amazingly effective at monitoring temperature and humidity, with accurate readings and easy setup. These are very well build, and looks very sleek.

I purchased this after reading an online article. I ordered them and they they arrived without incident dent. I had them open and installed to home assistant in about 10 minutes for both of them. They we're automatically discovered. I did need to install an app. They connect via Bluetooth, one directly to the home assistant raspberry pi, and the other via a Bluetooth proxy. I already had. All the normal home assistant utilization and graphing information is available to me. I almost immediately ordered two more. Really can imagine how set up could be any more straightforward. Highly recommend
