Cumulus MX - How to send data to Windy

doudidou

Hello,
Is it still possible to use CumulusMX?
Because I created my station (f07ba109), on the current version of Cumulus I entered :
Station Index : 0
API Key : ey*********************************************************************(...)
By the way, every time I refresh the page, the API Key is not the same when I click on "Show key", so I put in CumulusMX the last one I saw and copied.

And unfortunately Cumulus sends me back an error message, the connection to Windy failed.

Thanks !

Hi, it may take several hours till the stations shows up on Windy. When did you set up the station?

@korina Hi
I have programmed Windy for about 2 days but I just deactivated it while waiting for the solution because I get this cumulus error every 5 minutes : HTTP uploads are failing.
Last error: Windy: The SSL connection could not be established, see inner exception.

@doudidou Hello, our developers will look into this and find our if there is any issue on our side.

Is it possible to send data from Cumulus 1, the original from which MX evolved?

There are no specific options for Windy, only Weather Underground, PWS, Weatherbug and WOW.

Korina

@ott-drones Hello, then it is not possible, if there is no option for Windy.

Im having the same issue with CumulusMX 3.14.0(3159)

Windy: ERROR - The SSL connection could not be established, see inner exception.

Is your SSL certicate still valid?

I'm having some issues in sending data to a New Station
I'm getiting the following Error

2021-12-31 14:20:02.527 Windy: URL = https://stations.windy.com/pws/update/<>?station=0&dateutc=2021-12-31+14:20:00&winddir=233&wind=2.1&gust=5.4&temp=14.8&precip=0.00&pressure=10.1551&dewpoint=12.5&humidity=86&uv=0.0
2021-12-31 14:20:02.850 Windy: ERROR - An error occurred while sending the request.

Have I missed something out somewhere?

I got it all working.

I'm now having some issues again after after my Weather Computer Crashed.

I'm now getting the

code_text

2022-01-08 20:40:00.353 Windy: URL = https://stations.windy.com/pws/update/<>?station=1&dateutc=2022-01-08+20:40:00&winddir=293&wind=1.7&gust=4.9&temp=6.2&precip=0.00&pressure=9.9340&dewpoint=4.7&humidity=90&uv=0.0

2022-01-08 20:40:00.649 WeatherCloud: Response = Success (OK): 200

However since the Crash it seems like all the values are recording as Null.

My Station ID is ID: f048de60

Hello, this is an issue on your side probably. Try to restart the system.

@korina
Any idea what the issue could be, as the data looks like it's being sent through ok.

And it's accepted.

Also when I try and retrieve the API Key for my Station it always seems to regenerate a new one.

Is this expected behaviour?

@sjg1976 @Korina
I think I've resolved the issue.
The Time wasn't set correctly, I've synced this with an NTP Time Source and that seems to have resolved the issue now.

Problem solved
Your SSL certificate (Let's Encrypt R3 intermediate CA ) expired on 30 sep 2021 but the raspberry pi running cumulusmx still use it, so the solution was to disable the ca-certificate.

sudo apt install -y ca-certificates
sudo sed -i '/^mozilla\/DST_Root_CA_X3.crt$/ s/^/!/' /etc/ca-certificates.conf
sudo update-ca-certificates

PS: My station ID is f04aba5b

Hi,
are there any issues with this or is it still working?
I've setup my cumulus and wanted to upload to windy but I always get a bad request error like:

2026-02-11 23:10:34 - Windy: ERROR - Response = BadRequest: {"update":{"update":{"stations":[],"observations":[{"si":0,"time":"2026-02-11T23:10:00.000Z","temp":11.5,"wind":1.8,"wind_dir":340,"wind_gust":5.8,"rh":85,"dew_point":9.1,"pressure":98300,"precip":0.1,"uv":0}]},"errors":{"observations":[],"stations":[]}},"result":{}}

My station is dm5ptVB.

I created an API key and on cumulus I'm using 0 in Station Index and the API key created on Windy. Although I'm confused with this stated on the API keys page:

An API key cannot be used to update observations for your station. You need a station password for that.

@Paulo-Nóbrega The difference between the API key and the station password is explained here:
