It sounds like the UDP broadcast or API could be used to talk to Weewx. For remote applications this could be useful, for example Santa Cruz Island. Is the 120V indoor device powered directly from the line or with a wall-wart? If a wall-wart, what's its output? Unfortunately there are a lot of personal weather stations around that aren't particularly weatherproof. Anemometers fall apart, electronic packages fill up with water, etc. The commercial stuff is like an order of magnitude more expensive. It will be interesting to see how this unit holds up in a few years. I think SBARC has gone through several and wound up spending big bucks on the commercial stuff. From what I've read on their website it gets rather confused by snow. Its acoustic sensor doesn't detect snow well if at all and the snow builds up on top of the device rendering the rain sensor useless until it melts. What would be cool would be for them to incorporate a weight sensor for snow. -- Jay Hennigan - jay(a)west.net Network Engineering - CCIE #7880 503 897-8550 - WB6RDV

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.

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/.

Here is a link I should have sent in my original post which shows the output of my station: <https://tempestwx.com/station/20766/> Click on the tempest ICON at the top right for a different view (I like it better).

WeatherFlow Tempest no moving parts home weather station

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. Here is a link: <https://weatherflow.com/tempest-weather-system/>
