Send your station data to Windy (and others!) from Wunderground, MyAcurite, Davis WeatherLink, Weatherflow Tempest, or Ambient Weather

@markdj Sent you a chat on here. I'd need help from someone who has access to a Netatmo station already to get this to work, but it looks possible. Feel free to DM me on whatever platform you prefer: herzog.tech

Hello friends!
I’d like to throw my own data forwarding project into the ring. I’ve been using it for a couple of years and it’s pretty battle-tested at this point.
https://github.com/leoherzog/WundergroundStationForwarder
This is open-source code built to be run on the free Google Apps Script platform, no local hardware or internet connection required. It automatically takes readings from your weather station's API and forwards them on to any services you choose, including Windy and CWOP. Take a look, and feedback welcome!
Thank you so very much, I was able to send data to Windy from Ecowitt and only took a few minutes to setup, your tutorial is simple and very easy to follow, unfortunately I'm not overly tech savvy and the people over at WXforums were offering advice, it just got too convoluted but yours was simple and just works.
Thanks again.

Thanks so much for this!! It works perfectly with the Ecowitt data!
Quick question to anyone that is forwarding data to Windy with via Ecowitt. I run 9 Ecowitt HP2553 weather stations through a Facebook group and wanted to forward multiple stations to Windy. Is that possible through the script?
I've added a script snippet below. Is this correct?:
30 const ecowittAPIKey = '3c40c79f-0242-455d-950b-5d5dd56ff331';
31 const ecowittApplicationKey = 'FDDB8D4B58AC928BB141E55A6B756B68';
32 const ecowittMacAddress = 'C4:5B:BE:6D:EC:43';'7C:87:CE:BC:5C:DF'; -
@Eben-Atwater I wonder why this message shows, or waht I am not doing properly, as I try to get dat from Davis or Wunderground and forward it to Windy.

@Msrcello-Lacroix Did you ever figure this out? I'm getting the same error on the fetch attempt from weatherflow. The key ("weatherflowPUT") and station ID are entered correctly.

@Gregory-Haney I did not try to solve it as I got other priorities :) But am still dealing with the issue :(

Hey i'm having a issue where I run the script but it keeps on giving me these errors. I'm not very good at java and I been trying to get my weather station onto windy. I already have registered my weather station onto weather underground. It could be cause I have a VEVOR weather station but i'm not sure . Can you help?

Hello, thanks for your work. Really admirable.
I have followed your instructions and the transfer from weatherlink to windy seems to work except the precipitation ...
On the first go around (see 1 in attachment) all the rain in 24hrs was acumulated adding up to hundreds of mm's. Then I copied the gs.code anew and now (2) there is no more rain reported ... I must be doing something wrong .. can you advice? Thanks a millions so much for your help!

@HenryB_Sydney Hi! Sorry, I forget that this forum exists.
No, this is not valid syntax. The code would need several changes to support multiple input and output stations on the same platforms.
Have you considered simply creating two Apps Script projects?

I have been unable to successfully send data to Windy from my Tempest using the newest version of your script.
This is the error that shows up in the Executions list
Jan 19, 2026, 1:13:09 PM Error ReferenceError: windyStationPassword is not defined
at updateWindy_(Code:1258:29)Prior to this, I was getting a completely different error in the previous script. I was only able to get my station to show up once for few days and then never again.
Any ideas? -

@kostinha I removed your screenshots because they showed your Windy station passwords and API keys.

@marekd thanks
