Tempest app : first experiences

I may have missed this earlier as I’m a new owner, does the Tempest app not allow configuration for uploading to wunderground?

I’m not seeing it either. It used to be in settings under the Public Data section for a station. Maybe @WFstaff will respond.

I just checked tempestwx.com for my station and the link to Weather Underground is still there so this may be an app issue.

A post was merged into an existing topic: Bugs : tempest weather app

Having purchased the weather station for the exact same reasons, I have no issue with the app. I don’t use the app to display my data, I only use it to glance at temps, and view the forecast and soon radar. For the detailed stuff I use the API and a plug in for my home automation and it all works awesome.

Here is what I find frustrating about comments in this forum. Rather than going to the appropriate forum thread and putting in a feature request for a setting to allow users to decide which interface to open by default. Several folks in here just decide that pissing and moaning about how they’ve been wronged is going to serve them better. In my 50 years that has never been the case. Weather Flow’s customer service is stellar. Everyone I’ve communicated with has bent over backwards to make things right for me any time I had a question or concern. For what it’s worth, I’ve requested this feature on those people’s behalf. Not for me, I really like the new ui, but because I can see that others want it.

The think to do would be to go to the feature request section and me too that request so that their developers know it’s worth their time.

hopping off my soap box now.

Tempest is fully capable of sending data to weather underground. They are just having us hold off on this until the beta is over. It was present and functional in earlier beta versions but we were asked not to use it yet. They probably felt it was better to just remove the option for now. It should be back.

It’s only been in beta for a week or two. So give it time. They are changing things almost daily.

overall the app seems fine and obviously designed for phone type devices , the auto refresh is very annoying if your actually scrolling at the time or viewing a particular day forecast .using on ipad pro the GUI is not very intuitive from personal perspective too much white space lack of any real standout design thought for different devices . however its only a 1st version and dont go down the road of thinking im trailer trash talking it just I spend a lot of time doing design work and i know the possibilities of what can be achieved with some thought. it looks better on iphone 8 than it does and iPad pro.

Just want to make sure I understand this correctly. The app and webpage will display the raw readings from the Tempest sensors correct? If the unit is installed on the roof and it’s exposed to the inversion later, will it report the inversion temp (which is several degrees warmer than 5ft temp)? Or will there be an offset in place that it will report the temp that would be at 5ft height above ground?

How does WeatherFlow calibrates the sensors that goes out of calibration? Meaning what reference or standard would they use to make those calibrations? Especially if there isn’t a NWS weather station close to the Tempest unit.
@dsj @WFstaff @GaryFunk

While this isn’t a complete answer to your question, I found these using the search term ‘calibration’:

I personally don’t have any tablets. But occasionally I’ll bring the data up in a web page. I agree that the display isn’t very efficient on larger screens. I posted that in the suggestions section a few days ago and staff hearted my post.

Thank you all for your thoughtful input regarding thermometer siting standards and how this applies to Tempest. We wanted to clarify our approach to this and how the temperature data is treated. Tempest’s goal is to provide accurate temperature readings from the location it is mounted.

  • Accurate readings: Height has been mentioned here, but keep in mind that official standards also call for temperature readings to be taken inside sufficiently large radiation shields, with active ventilation if necessary. The Tempest temperature sensor of course has some shielding, but strong direct sunlight and light winds will result in warming that overpowers the preventive capacity of this shield (true for any small, non-actively aspirated shield). Through data from the field test, we have been able to empirically derive the required temperature adjustment given the wind and solar radiation observations. We will soon turn this on for all Tempests, and you will see readings approximating what would be taken inside an aspirated radiation shield mounted at the same location as your Tempest.

  • From the location it is mounted: Tempest will not attempt to standardize temperature data for height. If the device is mounted at 28’ AGL, it will give accurate readings for 28’ AGL, applying any necessary temperature compensation described above.

The CWOP siting guide is a great reference, but for the vast majority of home users it is simply not possible to meet each guideline (especially being 100 ft from any concrete and no closer than 4x the height of any trees or buildings). That is ok! Fortunately there is nothing illegal about measuring temperature in a spot that doesn’t check each box, and these aren’t climate reference stations. We encourage you to consider your unique siting challenges/opportunities and observational needs when deciding where to mount your Tempest and not to be discouraged at all if your options aren’t ideal for every parameter. The hardware is but one part of the Tempest system that also includes leading-edge software and data analysis.

No individual observation from the Tempest hardware network is likely to be ‘perfect’ in the traditional sense, and it certainly doesn’t have to be for it to improve the Tempest system’s ability to provide you with the best weather data available anywhere. A common saying among observational meteorologists is that “the more you know about an observation, the more useful it is”, so we do encourage all users to keep their metadata accurate and up to date. Doing so will improve the data you get as well as make your obs that much more valuable to the wider network.

100% thanks for your honesty it goes along way as we sometimes get a bit fed up with the fan boy responses ,works well in the home automation replies however thats good but thats/they are not answering some of the questions its merely sidetracking and not directly answering hence you may see a few get somewhat peeved and coming across abruptly . some of us want solid answers technical answers with that what we are basically looking for is some solid trustworthy information as you just gave…so thank you …

Am trying to understand what your saying. If you had a Tempest on your roof 5/6ft above roof - without the new software working – the temp read 100 – on the ground was 5 to 6ft above read 95/96 – with the Temp software working – on the roof - temp would be 95/96 – and or it would be 97/98 - using the Tempest software to adjust for being 5/6ft above the roof — using height/solar/other variables to give the most accurate temp

Is there anything we can do to cook up some kind of pseudo Stevenson screen ? Given the location of the solar panels, I’m thinking perhaps not, but is it worth the effort ?

Can we get a skeletal exploded view of the Tempest or a teardown from somebody perhaps ? Where are the actual sensors located ? Can we MacGuyver up something to make the situation better without messing up the readings ?

You can put the Tempest in a stevenson screen and it will be perfect for humidity and temperature readings if the screen is again set in perfect conditions … but how is the Tempest going to see the light ? Get the wind or hear the rain ???

As mentioned by Tony, Weatherflow has the data to compensate for the shield effects and testing I did proves it is pretty close to a reading I get in my stevenson shield (big enough to hold about 20 Tempest devices). This is because the elements are known and fixed.
For hight compensation it’s another story. The environment isn’t know and so many little details can influence and I don’t think a mathematical model cold include all variants. It isn’t just height.

As Tony stated, most of us can’t have the ‘perfect’ siting (for sure i can’t with so many oaks around and a canal flowing in my garden). And this is the reason why I started fooling with a weather station, the nearest VP2 (in almost prefect siting) just doesn’t reflect what I get in my garden. We can have easily 2°C difference and I don’t talk about humidity levels …now who is right, who is wrong … none are wrong.

And this is what becomes interesting about Weatherflow. The network becomes so populated that all those little differences become visible. And I’m sure over time all those data will help understand the micro evolutions of weather and the growing influence of what the human does by building houses, making roads etc.
And over time we can get more accurate data for our location, something satellites can’t do nor the official stations that are just not dense enough.

i don’t think that would improve. Assuming weatherflow did their physics, they are going to correct the temp measured inside by the sensor for the amount of solar irradiation it receives (and perhaps the amount of wind that cools it down). If you would shield the temperature sensor, the correction would turn out incorrect.

Would WeatherFlow consider including the Altimeter pressure reading along with the station pressure and SLP on their app and web app? Plus, could WeatherFlow add a feature within the app or ifttt for the user to upload current conditions to CWOP and Twitter?

If you scroll down the main page both the standardized pressure along with the Station pressure is given.

I think it should be somewhere on top of the screen Bugs : tempest weather app.
but to have three different pressure values is a bit too much. Why would you want an altimeter pressure, are you planning to carry the unit with you while rock climbing?

I know it shows both station and sea-level pressures. The NWS uses Altimeter reading in their reports and I personally like it the best.
