Topic: Upload current conditions to WeatherLink without using app

[weatherdj]

I noticed my WeatherLink desktop app posts current condition updates every minute by making an HTTP PUT request to the URL http://wl6.weatherlink.com/bin.php. It passes a payload of ~120 bytes in hex format that contains what I assume is all of the current observation data.

Has anyone decoded this payload? I'd love to be able to post current condition updates to WeatherLink by writing my own custom script without having to use the desktop application.

Thanks for your time and any guidance you may have!

Yes, a few people have done so, but I've not seen it publicly documented anywhere.

Actually, I'm not sure that this isn't for the best. If the protocol were publicly disclosed then it might encourage all sorts of experimentation, including potentially from non-Davis stations. Maybe also, accidentally or maliciously, the result could - at least in theory - corrupt data ingestion at the wl.com server, though one would hope that the server code would be fully robust to this. There might then be a reaction from Davis with who knows what ramifications. I can imagine scenarios with adverse consequences for the community here.
