But still can take up to 30 seconds to give a reading on my phone, which is a little long I think.These looked promising, however they take WAY too long to connect. I bought a set of three, one for kitchen, one for bedroom and one for hallway. Each one of them take around a minute to connect and show the temperature. It should not take this long. They are unusable like this. Ive never know any Bluetooth device take this long. See video. Actually the video is taken when it connected quicker than usual.I’m considering whether to send them back. The only thing stopping me is that they were only £11 for 3 sets, and you can read the display without a phone anyway.No helpline or support either. Such a shame.And just realised that none of the three thermometers log data in the graph (like they should), and no settings page for this.Unhappy. Will probably return if they’re this bad.

As stand alone thermometers they are discreet, easy to read even if a little small, and a sticky pad is provided to mount on a wall. Accuracy is ok. When put next to each other and by the central heating thermometer there was a small variation between them, but nothing massive.The Bluetooth connectivity is great for monitoring temperature. The app initially scans for each thermometer when selected but if it cannot find the device after 10 seconds you can still see the history that is stored on the phone. It’s good for giving trends where heat is being lost.I’ve had the thermometers for a couple of weeks now, so battery life is still an unknown. The low battery warning hasn’t popped up yet!

I ordered these devices as they could be connected to an app and it was a 3 pack for not a lot of money. The devices themselves seem to do the job adequately but forget about the app.The problem with the app is that it connects to the devices via bluetooth (I just saw wireless in the description and thought WiFi which was a schoolboy error). I live in an old cottage which has been extended over the years, some of the walls are early 2 feet thick and others are just stud walls. Because of the former, the bluetooth doesn't work unless you are standing in front of the device, so completely pointless. The other issue is that there is no backlight on the things so you will need a light source of some kind to read them when it is dark.Going up and down stairs to read different devices is far from convenient and not what I actually hoped for when I bought these devices but a little bit of extra exercise won't kill me.If you live in a modern house with stud walls and that isn't a bit of a rabbit warren like my house, you will probably see the full benefit of these things. If you have a traditionally build house, either give these a miss or be prepared for a bit of exercise.

This is rather too small to be useful in my opinion, the dimensions stated are correct but the main digits are less than 1 cm tall. Wildly inaccurate temperature suggesting 25c when the room was at 20c, then a few seconds later drops to 24.1 c . It redeeming feature however is in the software which reads the data from the thermometer. The temperature and h7midity is stored on the device every hour for the app to retrieve when connected. A good feature.

Nice little devices, small and discreet. Work well and temperature tallies with other devices in the house.Where it falls down is the app. You can only review the last 24hs by the hour, after that you can only see the high and low of the day.So if you’re trying to see how the temperature in room changes throughout the day over a number of days you can’t.There’s also no export function, so you can’t take the data somewhere else to analyse.These are software issues, so maybe these things will be added to the app. If they do, I’d definitely up the stars.

I bought this for my dauther room. I was needed a hygrometer. I already had a thermometer and I was pleased to see that both of them were showing same temperature. So it's very accurate. Very simple to instal and to use the app. I love the fact that you cand stick it wherever you want (i put in a hidden place) and you just check it from your phone. I don't need to go to my baby room to check it I just check the app. I would have loved to know about this item since my baby was born :)

I have this in my sons room as our house is quite cool and it works perfectly. The app is really easy to set up and gives you a graph showing the temperature and humidity in the room you set it to.

This is has bluetooth connection and not wifi as written in the title. Works okay but you have to reconnect every time you open the app to see the temperature. Also, there is a bit of discrepancy between the temperature displayed and the temperature which is saved in the history- not a problem as the correct temp is always displayed in the app but just not saved as this temp in the history.Overall a good product and good for what I need it for and good value for money.
