Wireless Thermometer Hygrometer, ORIA Mini Bluetooth 5.0 Humidity Temperature Sensor with Data Export and Alerts for iOS Android, Smart Real-Time Records for House, Wine Cigar, Living Room, Baby Room

Nothing to dislike about the device👌. It is small with a nice attachment loop for easy placement. And it worked straight out of the box. No complications.Once I downloaded the Android App, from Google, I calibrated this device with another of my thermometers/hygrometers that I know to be accurate and there was a little +/- needed on both the temperature (-0.2'C) and humidity (+0.5%). I have had this device for a week now and it has settled in, happily😎.The App is Bluetooth connected to the device and gives me all the information that I require. The temperature, the relative humidity, Vapour Density Pressure, a Mold Risk Warning, which thankfully has been 'Low' since I started my grow and is a handy extra bit of information to have to hand. The latter which I was not expecting but am pleasantly surprised about😲.Also, the data logger is very useful to see the history of the readings and can be exported to a pc.I reached out to Sensor Blue via email about part of the App screen not being visible on my phone and Sensor Blue responded promptly with their representative Zhao Kevin being very helpful. As it turns out it was a setting on my phone that needed adjusting. I had to adjust the "Display Size" in my phone settings and had nothing to do with the App👍This is my very first grow of a plant that requires very specific conditions and this plant does not grow naturally in Ireland, the UK, and Europe and will suffer if not attended to properly. This Thermometer/hygrometer is perfect so far and is a great introduction to me being aware of the current conditions within my growing environment so that I can make environmental adjustments to grow plants happy and healthy🌱🪴I recommend this device to anyone looking to be aware of their atmospheric conditions for whatever reason but for my purposes, it ticks all the boxes✅.The assistance from Sensor Blue via email was 5 Stars⭐⭐⭐⭐⭐For this price, the device and accompanying App are outstanding value for the money. And the technical backup is excellent.😁😜🤩

First thing to note is that there is a limitation not noted - you need to have location enabled for this to work (a common requirement for android bluetooth connections). Trying to use the software on a device without GPS was impossible - I should have thought about that before buying it.Once I loaded the software onto a device with location enabled it worked well.I've tested the device in a number of locations with good success. It records every ten minutes. Once you connect with the app it downloads the recent data. It can be shared easily.I've tested it against two other devices and the accuracy was really good. The range was not as good as advertised. I found the range was about 10m through one wall.Very pleased with the functionality of a device that is this cheap. Got a second one now.

I'll start with my pre-purchase prejudice - I had very low expectations here. At this price, how could they work? I'm still not sure how they can work but they do work and they work brilliantly. They connected initially to the app quickly and easily and I download the sensor's data over Bluetooth from about 10m away. The only negative is the display on the app - I've just opened it and it is showing data from 2 weeks ago and showing 01:21 and 04:39 rather than 01:30 and 04:30.

A surprisingly simple device that just does what it's supposed to for little money.I bought this to experiment with the possibility of giving me the temperature and humidity outside my window. Now this device is not waterproof so needs some thought in where you locate it. Having worked around temperature and humidity measurement all my life, I know a bit about how difficult humidity is to measure. For a start it's Relative Humidity, so relative to what? So this little device has to make a measurement (not too difficult to make) but then has to turn that measurement into a meaningful value compared with the possible value of the same air when saturated with water, which is influenced by temperature, atmospheric pressure possibly altitude and many more. So the designers have to make some well-thoughtout assumptions. These they build into algorithms to give you a relatively accurate indication of RH! What this device does (and does very well) is give you a fairly reliable indication of change. It is not intended to work across the full range in laboratory applications. If you like me want to know if the weather outside is changing or that your plants are safe in the terrarium or greenhouse, if you are just looking for relative changes (has it got warmer or more damp?), it will work fine!The device and software has some surprising features that only used to be on expensive systems. It is possible to offset the displayed value (I avoid saying calibrate) to make it track more closely other measurement systems or just to allow you to see the values you are expecting to see. It can act as a data logger and store a number of measurements that you can download to your device later. You can see these results as a trend chart, histogram or as data points on your device. If you have a number of devices, you can name each one individually to make the results more meaningful on your device. One small niggle, the display remains in portrait mode: it won't display in panoramic.Concluding, excellent product for little money, will probably buy more!See this one as well: https://www.amazon.co.uk/ORIA-Thermometer-Hygrometer-Temperature-Notification/dp/B089ZWJDMV?ref=pf_ov_at_pdctrvw_dp

I bought two packs of two….. one was perfect, with the other pack, one of the two works occasionally, but not reliable enough to be useful. Was refunded of course. So great, but I worry how long the survivors will continue working for. App a bit limited too.

It works. App is not great but you can see the temperature and humidity. Humidity measure compares well with other meter I own.
