Title: Retrieve weather station data from weatherlink.com
Post by: PLCwannabe on May 05, 2024, 11:57:39 PM: I'd like to access weather station data on weatherlink.com with a brx with onboard ethernet. Attached is a screenshot of the API token that I think I will need to communicate. Just looking for general direction on how to get started, maybe a link to a domore help topic.

Api Weatherlink data: https://weatherlink.github.io/v2-api/

You would most likely use the HTTPCMD instruction in the BRX and in the http Server box, set the by Name to "weatherlink.github.io". Then in the HTTP Request box, use a Request Method of GET, and set the Request string to "/v2/..." where the ... would include your weather station's id and your api-key. But you'd have to consult WeatherLink's documentation to find out the syntax of that request.

Check "Use SSL/TLS" in the HTTPCMD editor.

TLS requires a DNS name, or at least the stack we use does.

There is not. For whatever reason, the TLS stack we use insists on a DNS name.

It's a huge rabbit hole, but perhaps you could have a DNS server on your network, and then have a DNS name to go to that IP address? I'm not entirely sure what it would involve, perhaps your router can handle it. Or a pi running pihole.
