Since hams seem to be intrigued by weather (or, at least they seem to talk about it a lot on the radio - perhaps due to nothing else to say, or to kick start a conversation), I thought people might enjoy hearing about this new device (UUQ especially maybe for Santa Cruz Island). There are no moving parts.  This station  measures rainfall using the sound of droplets hitting the top of the device (no tipping bucket). This also measures wind direction and wind speed via sonar (no spinning cups).  It does mathematical compensation to arrive at the proper temperature despite being in direct sunlight.  It was purchased for me as a gift via a KickStarter program.  I think it was $280, or so.

Ken, at first glance it's cool. What's on the receiving end?

I run an application on my iPhone that shows me the data. There is a 120V device that sits in the house the grabs data from the station wirelessly (not sure of the protocol) and then pushes it either to their server or to my iPhone (not sure exactly how it works; likely to THEIR server as I believe I can get results via my iPhone application when remote, but haven't tried this yet).

I have a Peet Brothers weather station and it connects to a Raspberry Pi running Weewx. This allows me to view it locally as well as upload to Weather Underground (No, not THAT Weather Underground).

You must clarify the parenthetical... I'm missing something (likely "Jay humor" which is often above my brain power).

I also have Open Sprinkler that monitors rainfall, humidity, and temperature. This controls garden irrigation and adjusts water time based on recent and predicted weather.

Their website is kind of limited in technical details, but at first glance it looks like the data you get from it is via some cloud based service and an app. This wouldn't work for me but if the data can be pulled locally without "phoning home" to some service over the web and imported to Weewx via some form of API it would be sweet.

I opened a ticket last week to find out how to pull data locally and they came back with multiple ways:

"There are many ways to collect the raw weather data from your Tempest system. One of the easiest is via the IFTTT applet that automatically posts your station data to a Google spreadsheet. See more on using IFTTT with WeatherFlow devices here: https://ifttt.com/weatherflow. You can also leverage our API services to pull raw data from your station: https://weatherflow.github.io/SmartWeather/api/. Another way to download your data is to use our UDP Broadcast service which does not require an internet connection: https://weatherflow.github.io/SmartWeather/api/udp.html."
