Hello everyone.
I use the interval of 10 minutes at Weewx. Now, of course, the fine dust pollution is only measured at ten-minute intervals. Is there any way to set this interval to every minute? Then it would also be possible to save the particulate matter values ​​in a separate SQLite database? Has that possibly already run someone of you?
It`s the original Davis Air Quality Sensor.


Thank for our Help`s

You can by setting your archive interval to 60 seconds in the weewx conf file here


[StdArchive]
   
    # If the station hardware supports data logging then the archive interval
    # will be downloaded from the station. Otherwise, specify it (in seconds).
    archive_interval = 300

Now with the Airlink driver, you may get a timeout from the API if you poll it all the time. John Kline has another repo that creates a proxy service for the airlink driver. that repo is here : chaunceygardiner/airlink-proxy: Proxy server for Davis AirLink air quality sensor. (github.com)

Hello Doug.

 

Thx for the Help. I've tried to somehow get that with the proxy. But unfortunately without success. Since I'm not a professional in such things, for me it's mostly stationery what's written there. Is there a more detailed guide on how to install this proxy? How can I start it afterwards and check whether it is running?

Excuse my "dummy" question ;-)

No problem. I reviewed the airlink proxy code and it is a bit of effort to get setup and configured. I personally do not use the proxy as I am just polling the sensor every 5 minutes.

What I would do for now is just setup the weewx airlink driver with your station and set the archive interval to 60 seconds and see how that goes.

Hello Doug
I have a question. It's now been 2 years since my last post. My search didn't turn up much worth knowing either. That's why I wanted to ask again whether anything has happened in these 2 years regarding the reading of the fine dust sensor. The aim would therefore be to write the measured values into a separate database. The goal would be to discharge every minute. I want to save the weather data, i.e. not reduce the interval to 10 minutes, as this has no meaning for this data.
Greeting
