I assume you are talking about the 5 wind meters? These are used to provide wind speed and directions for various activities such as surfing, hunting, sailing, etc. Not exactly useful for measuring any other weather phenomena. Nor do I think they actually invented these wind meters, they have been around for decades.
weather display is already ready
That is a program that supposedly takes weather data from hardware and displays it. It's just code. Where is the
hardware? I see nothing on their web site except
pictures of that supposed
hardware. Nothing that could not easily be created with the average pixel editor. Please provide a link to a review or even a site that actually sells this hardware. I'll even settle for a site that mentions "Weather Flow" other than their own site.
The weather34.com link is just for the software (an API) that is supposed to be able to access the data from "Weather Flow" hardware, when and if the hardware is ever created. That hardware is promised to provide certain items of data. They are listed on that weather34.com page. That's the same data that WC would use if it was available. Note that it is supported by meteobridge and "Weatherflow". Davis hardware is "coming soon".
The github link is simply a place that developers help each other, if they want, with programs they are creating, editing, correcting, sharing, etc. It has nothing to do with the hardware.
The WeatherFlow site claims that their hardware will have a range of "1000++ ft". That range is possible with a directional antenna, but there is no mention of that even in the "Siting" section. Here's
a good explanation of normal/typical WiFi signal range and why it is usually so short.
The indiegogo link is to a page offering people the "opportunity" to purchase hardware that may not even exist. As it says, "Estimated September 2017". There are several sites like indiegogo, read their "How it works" page. It is a "crowd funding site". It is a way to get monies from people willing to
lose their cash for the
chance of having a new product before any one else on their block. These sites are often heavy on promise and very lite on providing the product. These sites are mainly used for future, promised products that major financial funding sources won't support for one reason or another.
Please do not send them money based on nothing more than a web site
unless you can afford to lose that money. It is much more risky than any stock market.
The answer to your original question is probably: "When the Dev has the
time and here are signs that a large
enough number of
Mac users using the hardware." I doubt that anyone, including the developer of WeatherCat knows when that might be. I do wish the Weather Flow folks good luck, it
sounds like a great product for many.
Please remember, these are my biased (by age) opinions and are worth exactly what you paid for them!
