It is now 3.2024 and I have been monitoring the battery in the original sensor and it is holding up fine. Since the initial purchase, I acquired 3 more HTP.xw devices to use in various locations. All are working flawlessly and side by side there's only the slightest difference in the readings < 0.02%. I decided to take 2 of these units and put one into 2 freezers for monitoring. I was unsure if they could communicate with the hub due to distance and obstruction. No problems at all. One is on a porch with a garage freezer and has to comm through the steel box, and a 6" stud wall. I didn't expect a problem there due to proximity. The second unit is in an older freezer with refrigerant lines attached to every shelf. This box is bigger and heavier than the other appliance due to manufacturing differences and quality. This unit is also 25 feet from the hub and obstructed by 2 six inch stud walls- one full of copper plumbing. Also in the path are another freezer and a hot water heater, No comm problems here either. I have to admit I didn't think this would be a success because of location and obstructions- and I was amazed at the performance.
I'm ordering 2 HTP.xw units today to replace the ones I moved into freezer service. My next curiosity is how long the batteries will last in the sub-zero environment. I'll let you know- but I don't expect any issues since one of these units is on an open porch, and the winter temps here have been pretty harsh since installation- this last winter the exception. I may report on this a bit later in the year...
Don't hesitate to try these devices. The phone app is very good and because I have the hub, I can get data and notifications from anywhere via the Android phone.
---------------------------------------------------------------------
OK- This has been a long time coming. I made sure that I operated these devices for almost 90 days before rendering an opinion- it's only fair.
I purchased my SensorPush HPT.xw device in early February this year, and installed it a few days later. I had some questions about installation and settings, so I contacted the Customer Service Dept. My questions were completely answered and I even got additional information that proved valuable. I once again contacted then for a different reason and not only did the rep remember my earlier conversation, he solved the current problem on his end without any trouble. This is 100% customer commitment - in the Amazon tradition - something you will have a difficult time finding elsewhere.
On to the device: I basically used a thick cable tie to attach the sensor to my air conditioner frame that extends onto a covered porch. This will of course, change as soon as the weather warms up! I made sure that the device was hanging in free air; would not be in direct sun; and also where it would be facing into the prevailing wind. The latter is important for accurate RH and DP readings.
Pairing it with a Bluetooth smart device was a breeze. But, what was even better was setting it up with the SensorPush WiFi Bridge that allows me to access readings from virtually anywhere I have Internet connectivity. A simple cable to my router was all that was needed (aside from power) and I was connected in a matter of minutes. The range of the device to the Bridge is very respectable and should work in tha majority of installations. Also note that I have a second SensorPush device. I'm using the HT.w to keep tabs on my well water system in a stone cellar. This promptly alerts me if the temperature is nearing the freezing range. If I am not at home, the Bridge sends out the warning and I can act accordingly.
Now for accuracy. I tested the devices by using professional grade mercury thermometers over a period of several days. Apart from the cold, I made sure to do this in the warmer temperatures we are having now. I found the accuracy to be within one degree either side of what the calibration thermometers indicated. No, they were not in the exact same spot- but close enough for most every application.
I verified the DP and RH readings by comparing the sensor's data with that of a sling psychrometer that I repeatedly used over many days to verify the accuracy. Again, the differences were minimal- one or two degrees either side of the professional instrument. Fact may be that the sensor is more accurate due to the nature of using a wet bulb / dry bulb comparison chart. In any case, no one needs to be splitting hairs for these readings.
The barometer proofing was a bit more complicated. I took the sensor and two temperature compensated, precision aneroid barometers to the local airport. All three were adjusted to the pressure on the tarmac. I then drove back home and mounted all three in the same spot. As expected the readings dropped by over one inch due to elevation. All three agreed and continue to agree right to the present time. I have since set the sensor to the "meteorological" option for sea level indication. I now have both station and sea level readings for my purposes. One note- barometric pressure is more a condition of trend rather than actual setting. If you are near accurate, the speed and amount of rise and fall of the pressure is the important data, not so much the precise reading.
Comparing this to other weather station options available: At less than one hundred dollars, I find this to be a great bang for the buck. Simple to install and operate, with very good accuracy and tracking functions. What's needed now is an anemometer and rain gauge for those of us who rely on weather as an important factor of daily life. I have expressed this desire to SensorPush- so hopefully they will respond with some more excellent products. And by the way, replacement batteries are available right here on Amazon- no need to hunt. Just search for CR2477 and take your pic. These batteries are inexpensive and long lasting.
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!

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!

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.
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.
