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

Excellent thermometer. Fairly good accuracy compared to other thermometers in my possession. Even more useful with Homeassisstant as I can automate fans/heating based on it. I've not used these without a switchbot hub, but with it I can see the historic temperature/humidty extremes.

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.

Let me start by saying that I own two of those. Bought for £16 but the price seems to have gone up. My needs range from using them in a polytunnel and greenhouse, to an incubator and even inside a fridge for meat curing. The good stuff first; - easy to setup with the app - battery seems to last a long time - quite robust; one of them has been sat inside a fridge for a while without a problem - you can infact calibrate them - you can export the data to a file The so and so; - I don’t think it’s accurate, in fact the humidity reported between the sensor and another humidity controller with a sensor is more more than 13% which is a huge variation. - even between them, their actual values are off. - the app keeps spamming my email about nonsensical promos - even though Bluetooth works, it’s often problematic with a constant failed message and having to retry again The problems; and bear in mind this greatly depends on your scenario - humidity inside an incubator (which has on average 85%) simply doesn’t work. Meaning that it isn’t really suited for wet environments. Ok the contrary temperature seems a lot more accurate - if you want the data from it you have to sync frequently. Not synching for a while is a huge issue as now you have to sit and wait minutes for the data to download. - for the price paid it was a good buy. But I wouldn’t pay more for it now. Ultimately it seems like a well made Chinese sensor. Their cameras are utter crap but this sensor is actually quite good.

Amazing. Allows for excellent monitoring of both temp and humidity. Excellent for pets and super fast to update. Get one for every room in your house with the easy to see displays. Great Bluetooth and smart home connectivity

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

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

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 !

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.
