Help with Windy.com upload

[Palometero]

I have a WeatherFlow Tempest running CumulusMX 3.13.4 b3149. I've turned on data logging and debug logging and all I am getting is

Code: Select all

Windy: URL = https://stations.windy.com/pws/update/<<API_KEY>>?station=0&dateutc=2021-10-14+01:54:00&winddir=107&windspeedmph=7.8&windgustmph=10.0&tempf=84.7&rainin=0.00&baromin=29.815&dewptf=76.7&humidity=77&uv=0.0

then I get

Code: Select all

Windy: ERROR - An error occurred while sending the request

Is there any way to debug this? I have Weather Underground working fine. Just trying to get the Windy.com upload working.

Any and all help appreciated!

First, try copying the latest URL from the log, and substitute your API key into it. Then try and use that URL in a browser on your desktop - I suspect it will work?

Thanks for the response @mcrossley Yes, it works. Got this:

Code: Select all

SUCCESS (valid measurements count: 9, valid station info count: 0)

So is the tag not getting replaced? How do you fix this?

[mcrossley]

I think it is a problem with your rPi. My Windy uploads were failing too.

Windy uses Let's Encrypt for their SSL certificates, recently (30th Sept) the Let's Encrypt R3 intermediate CA certificate they use to authenticate their client certificates expired.

The rPi has not kept up with that change and still has the old intermediate CA cert.

I followed this question and it started working the following day on my rPi...

@mcrossley, Thanks for that. I've updated the ca-certificates file. I'll let you know if that does it.

Ok, that worked. Thank you @mcrossley! I just got this:

Code: Select all

2021-10-14 09:42:00.236 Windy: URL = https://stations.windy.com/pws/update/<<API_KEY>>?station=0&dateutc=2021-10-14+14:42:00&winddir=107&windspeedmph=2.9&windgustmph=4.8&tempf=85.2&rainin=0.00&baromin=29.837&dewptf=74.7&humidity=71&uv=7.0
2021-10-14 09:42:02.395 Windy: Response = OK: SUCCESS (valid measurements count: 9, valid station info count: 0)

Now to see if it shows up on windy.com

So just for anyone else looking for an answer on a rPi 4, If you get a "Windy: ERROR - An error occurred while sending the request" in your MXdiags/somedate.txt. do this

Code: Select all

sudo nano /etc/ca-certificates.conf
Put a ! in front of the line: /mozilla/DST_Root_CA_X3.crt
Save the file: Ctrl-X, y
sudo update-ca-certificates

Mine took a full day before the data started showing again! It seems it doesn't like you going offline for extended periods.

Perfect reply, I had given up on Windy since the certificate change. The data started to come back on the site in about 15mins.

[Palometero]

It came up for me in a few minutes once the cert issue was taken care of.

I got this sorted out yesterday, but like Mark the data didn't appear on the site until this morning, although it has uploaded all the data since I made the correction

Had the same problem, CumulusMX running on "Raspberry Pi 3 Model B Rev 1.2".

Did a sudo apt update/upgrade, reboot then:

From the "stackoverflo" link from above used the solution

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

Reboot.

Running fine.

Many thanks again to the users/supporters.
