SensorPush HTP.xw Wireless Thermometer/Hygrometer/Barometer Extreme Accuracy Water-Resistant for iPhone/Android - Made in USA - Indoor/Outdoor Humidity/Temperature/Pressure Smart Sensor with Alerts

It’s really small, looks good and app responding fast. I’m using them at home to read C and RH (as standalone devices with Bluetooth). Tried to calibrate humidity with 75% kit. It reaches exactly 75. Both devices display the same numbers, so they are pretty accurate and calibrated out of the box. Battery drops from 3.2V to 3.0V in a few days, but now it’s stuck on 3V for a while (SensorPush says it should last for long). Readings refreshes every minute, app interface is very minimal, nice and easy to read.

Living in a van full time can be worrying for refrigerated products.Fridge is on at all times but at different times of year, especially summer, it's good to know the fridge is keeping up.Plopped one of these into the fridge and I an just check the temperature history at any time on my phone with Bluetooth.Amazingly simple and worth every penny

From the moment i opened the box and saw the carefully packaged sensor, i felt i was dealing with a true Measuring Instrument, well produced in every detail, right down to the rubber seal around the battery insert, and the handy hanging slot. (surprising how many other makers don’t have these on them)It’s a small but mighty addition to any growers toolbox, which along with the SensorPush App enables accurate, constant and recordable data measuring ofTemperature, Humidity and Pressure.With a bit of knowledge, a gardener is able to dial in their grow for the healthiest plant growth, right down to Vapour Pressure Deficit.As an added bonus, this little gem will alert you if it senses your grow has fallen below; or raised above the parameters you very easily set in the App.If you so wish, you can pair up the Sensor(s) with a wifi SensorPush Gateway, which gives you a central area base station as you add Sensors, and adds full wireless e mail alerts to the already featured Bluetooth ones, so you can be notified even when you’re out of range of your home or grow.Another great feature is the SensorPush customer service, prompt and intelligent query replies.Mark.

I use this top of the range sensor in my 6 x 6 home greenhouse and sometimes put it in the garden. I have housed it in a TFA Dostman 98 sensor screen (Amazon £12) to keep direct sunlight off it. It is extremely sensitive and gives to the minute updated professional level information (VPD etc ) which satisfies my need for accurate information. The bluetooth range through glass and walls is reduced from the stated range but is for me adequate. The app is excellent. Yes, it's a bit pricey but then good kit always is.If only they extended their product range (rain gauge, ground thermo etc) and made it thread and HomeKit compatible I would give it 6 stars. 😀I use it alongside it a separate EVE Weather device to control an EVE Aqua water switch. This gives reading updates every 10 mins but the excellent EVE and HomeKit apps, using thread, allow good humidity (and temperature) control.

I'm using this to monitor outdoor temperature, humidity (and pressure) as part of a project to assess energy efficiency in my house. So far I'm very pleased with the device. The software loaded without problems on my iPhone, binding the Bluetooth was quick and easy, the display is clear, and the little device looks good.It's interesting to compare against an older and significantly cheaper device doing similar things, which I purchased at about the same time, and my conclusions are that you get what you pay for and that more recent designs can be nicer to work with.A good point for the SensorPush range is that the software allows multiple sensors to be connected, which would be handy for comparing indoor and outdoor readings without any data wrangling in Excel.I've not had it long enough to comment on battery life, and I didn't buy a hub to enable connectivity over the internet.I'd probably buy more devices from this range, if I needed more sensors, rather than going for a cheaper device which would likely be more trouble to get going.

Good, very well designed product. Works very well, and mostly accurate. It does seem overpriced. It is promoted as “made in USA”, which is a turn off for me as products made in the US are never as reliable as those made in the Far East, sadly. It probably explains over pricing. We shall see.

Accurate, conveniently sized sensor. Great with the Gateway.

DIdn't realise how useful the data was until I bought this and the wifi gateway. Its been almost 4 months and not a day passes without me waking up to check the data. I use this to monitor my greenhouse and the data( mainly temperature and humidity) helps me to decide if I should leave door or windows open or if my fan setting during the summer is sufficient. Now with winter around the corner, the data has been invaluable as I can set the heating thermostat just enough to counter any frost as I can check from the graph, at what temperature the heating kicks in and set it accordingly so I don't waste electricity unnecessarily.
