SwitchBot Indoor Thermometer Hygrometer 3 Pack, Indoor Temperature Humidity Sensor with Smart Alert & 68-Day Data Storage, 3In Bluetooth Room Thermometer (Meter Plus 2Pack)

Fantastic indoor thermometer, great display and also very easy to put it on the wall. Thanks to the Bluetooth integration you can also check the room temperature and humidity from the switchbot app on the phone. Definitely recommend

Really impressed with this little sensor. It picks up changes in temperature and humidity almost instantly, and the readings have been consistently accurate across different rooms. Setup took seconds and the app updates are smooth and reliable. I like that it’s compact enough to place anywhere and still easy to read in the app. Great value for the performance — exactly what I needed for keeping an eye on the indoor environment.

This is a great little device, I’ve got one in nearly every room now. We use them to monitor the temp and have alerts setup for if any rooms get too cold or hot. Using IFTTT for automation I have a heater for my solar batteries in winter, so it keeps them at a safe temperature, I also have a fan in our cabin for when the humidity gets too high. I’ve only had one fail in a few years and the support team were brilliant and replaced it with no fuss at all, great device backed up by a great company !

I bought 4 of these to read temperature and humidity into my home automation. After sitting next to eachother for a day they were reading within 1% humidity and .1°C of eachother which is good. I'm deducting a star because you basically can't use the Bluetooth feature without creating an account, the app won't let you use it unless you create an account. Instead I built an ESP 32 which scans the BLE service data on these which contains all the information that's down on the screen, the protocol is open source on GitHub. It's disappointing to see companies force you into their cloud accounts and data collection to use the app but with a bit of effort you can work around it if you're willing. If the data collection and account creation isn't an issue, these are well worth the price. I bought one at £20 and a further 3 on sale at £13.99 though I believe they've been as low as £10 each. They take 2 AAA batteries but I can't speak to battery life as I've only had them a week. EDIT: A few months later; I had one die a couple of weeks in, the screen became garbled, unfortunately Amazon wouldn't replace it, only refund which meant I'd have to pay the now 2-3x the original price as the price has gone up significantly. The remaining units are working fine, in now using Home Assistants new Bluetooth Proxy feature with ESPHome with an ESP32 which works better than the original hack I had. I'll buy direct next time though as they give a bulk discount and I'm sure they'll replace faulty units rather than force me to rebuy at a higher price.

I was looking for an accurate meter that would record the temp and humidity and allow me to create historic charts so I could help trace our condensation issues and whether the changes we made were working. These meters are incredibly useful, the battery lasts for a very long time and they're easily replaceable (not like those meters that use annoying coin batteries), and get even smarter when they're linked to the switchbot hub - this allows you to see your readings from anywhere, not just via Bluetooth from the meter. I have these inconspicuous meters dotted around the house and they're great for keeping an eye on comfort levers and providing an early warning of any issues such as leaks or damp.

Works a treat. Easy to install. Clear display. Reasonable price.

I am a fan of the switchbot ecosystem and this temprature/humidity sensor makes a great additon to my switchbot setup. The display is nice and large making it very easy to read from a distance. There is a smiley face which alerts you to the 'comfort level' within the monitored room. The device is app controlled and you will need a hub if you want to control/view this outside of the bluetooth range. I have this installed in my loft to monitor my solar PV inverter, a quick check of my phone now lets me know what temprature my loft is at and if i need to switch on a fan to cool things down. Great device - works well

These little units are really easy to set up and use, and have a very nice clear display, unlike other hygrometers I've used. However, they don't work very well in that they don't easily connect to my phone unless my phone is within a couple of meters of the units, with no closed doors between them. And when they do eventually connect it takes ages for all the data to download from the unit to my phone (I'm talking more than seven minutes, which isn't really acceptable). I bought these because I wanted to be able to monitor the humidity levels in my house, in the cellar, the sitting room, and the bedroom, but the issues with connectivity and download time means they aren't fit for purpose. I'll be sending them back, sadly, and looking for something better.
