SensorPush HTP.xw Wireless Thermometer/Hygrometer/Barometer Extreme Accuracy Water-Resistant for iPhone/Android. USA Made Indoor/Outdoor Humidity/Temperature/Pressure/Dewpoint/VPD Monitor w/Alerts

I bought the whole set up which includes the WiFi router and five sensors that lets me know the temperature of all my rooms when I’m traveling. Three of the sensors have the capability of reporting pressure but only one shows the correct pressure as corroborated by my local airport. Unfortunately I can’t set the remaining two sensors to the local pressure. I hope they can fix this problem.

UPDATE Jan2024: Original review is below. Mom will still tell anyone who asks about her SensorPush and how it has provided peace of mind knowing that the pipes in her pump house are not in danger of freezing. She can check conditions inside the pump house from anywhere on her property including inside her house and determine whether the heater is active and how long it operates. She has had several instances with temperatures below freezing outside since placing this SensorPush and it has worked flawlessly to keep her informed. Just after Thanksgiving, I purchased an identical SensorPush for my wife's greenhouse. It is used during winter to protect our more vulnerable plants from freezing. I have been using this SensorPush to notify me when the temperature inside the greenhouse is nearing freezing so that I can go outside and turn on some heat. The greenhouse is solar powered (we drive a 12V water pump for rainwater distribution from our rainwater tank and use it to power the greenhouse heater). We have had several nights with temps below freezing and using the SensorPush app I have configured temperature warnings so that I can take action when the temperature approaches my threshold. The app is simple to configure and shows the SensorPush history graph for the 5 variables tracked in a way that allows one to see current and historical data at a glance with a simple, intuitive swipe or tap. I love the simplicity of the app and everything that I need to know about conditions inside the greenhouse is right there in front of me. As I mentioned, Mom can check her SensorPush from anywhere on her property, two standard city lots. I can also check data from mine from anywhere on my property of several acres except that initially I needed to be in one end of my house to be able to connect. I have a brick house that is about 100 feet from the SensorPush location in the greenhouse. Originally the signal would only penetrate about 12 feet into the house. I have a bit of experience with sensors, antennas, etc through my employment and decided that I might be able to improve that if I changed the position or orientation of the SensorPush relative to my location inside the house since many antennas usually have a directionality that can give them better range in one orientation than in another. With that in mind, I moved the SensorPush inside the greenhouse to a location 3 feet closer to the house (put it beside a wall parallel to the house where it had been on a wall perpendicular to the house) and changed the orientation so that the flat wide side of the SensorPush was parallel with the outside wall of the house. I went inside the house and found that this simple placement and orientation change extended the reach inside the house by 18 feet so I can reliably pull data from almost anywhere inside the house now. (My house is 40' wide in that direction). With a line-of-sight orientation outside on my property I can grab data from points that are more than 330 feet from the SensorPush. The building materials in the house and possible the interference from my wireless router affect the effective range inside the house but outside it tests the limits of the bluetooth technology it uses (advertised at 330 feet). I really like this device. One of my sisters has also mentioned that she will be getting some for monitoring conditions in her doghouses where she uses small infrared heaters to keep her pets warm on cold nights. I have included a few photos from my installation. The first shows the graphical interface of the app on an iPhone for the period Dec 23- Jan5. There are red areas visible on the curves for several days. I have set a warning in the app at 35F so that I know to monitor the temp in case it is falling and go out to turn on the heater. The second details the warning information and in that you can see where I monitored the temperature for about an hour as it dropped and then, just before midnight I went to the greenhouse and started a small propane heater which quickly bumped the temperature outside the frost zone and ran until it was out of propane around 4 am. At that point the temperature began dropping as fast as it had risen since there was no insulation in the greenhouse. The third photo (rotated on input for reasons I don't understand) shows that it dropped about 15F in one hour 45 minutes and at that point I started the small, 200W electric heater running from the solar battery array. The last photo shows just how wimpy that heater is. From the time I turned it on until dawn, around 7:25 am, it raised the temperature inside the greenhouse from 37.6F to only about 38F but it held it steady for about an hour and a half until sunlight began to warm the greenhouse at dawn. It works and using this SensorPush I have clear incontrovertible evidence of how well things are working inside the greenhouse which I can use to improve growing conditions. I have also included a photo of the SensorPush on the shelf and of the solar setup and some happy plants. This thing is fantastic. ORIGINAL POST: I bought this SensorPush with Thermometer, Hygrometer, and Barometer for my Mom to help her monitor temperatures inside a small pump shack near her garden so that she could tell when it might freeze and to make sure that the heater installed inside the shack is working. The order arrived on time according to the proposed delivery date and just in time for a rain/freeze event. Mom was able to set it up and grab the app for her phone and sync to it. It has been nearly two weeks with no hiccups at all. She can check conditions from her phone from inside her house or anywhere on her property. That makes a huge difference in the level of maintenance needed annually preparing that pump and the water distribution from the rainwater tanks for winter conditions. The only note I would offer to those who are considering buying one for themselves or to give as a gift is that the device comes with a battery. You do not need to go out looking for a battery when it arrives. Mom initially didn't see the battery in the package and she spent a while running around town trying to find one before calling me for assistance. I had read in someone else's comment that the battery is included so I told her to check everything thoroughly to make sure she needed one. She quickly located it and got it working. She said it was very easy once she found the battery amongst the packing materials. LOL. Mom is over 80. Though she's pretty sharp she sometimes feels intimidated by new technology. The SensorPush has become another one of her favorite devices. I want to thank those people who designed and built this device and coded the app that it uses. You have made a great product that does what it claims to do and it is an accomplishment to have coded an app that people of all ages can intuitively make use of. Great work!

Ce capteur petit et léger est de fabrication robuste, et fonctionne dès la pose de la pile lithium. La lecture des données se fait par BlueTooth, sur un smartphone Android ou Iphone. Il est facilement reconnu par l'application Android dédiée, et donne des valeurs précises. Ce capteur est plus cher que les concurrents, mais consomme très peu car il ne fait qu'envoyer les données sur demande, et reste en veille le reste du temps, selon sa programmation. Produit de qualité, à recommander si on est exigeant sur la précision et la facilité d'emploi.

I was sceptical in the beginning about the claimed accuracy especially for the relative humidity measurement. However, after extensive testing with a calibrated vaisala HM40S meter, several boveda humidity calibration sachets later and a fantastic support team behind this product, I verified that not only does this sensor adhere to their claimed accuracy, it is also a extremely precise. Specifically, I have 4 of the HTP.xw sensors and they all measure temperature to within 0.1C of each other and 0.1C of my reference temperature meter, as well as 1.2%RH. So being both precise (consistent) and accurate, they are perfect for those who care about real measurements. Coupled with the great smartphone app, and there is not much more to desire.

Funciona muy bien, da los parametros correctos ya que su sensor es de buena calidad, lo recomiendo y me voy a comprar un par más. :)

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 of Temperature, 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.
