Simple php script to upload Tempest data to OpenWeather

Developers Third-Party Integrations
1

Hi,

I am using the following php scripts, the first to create a station using OpenWeather API (run only once) and the second to grab data from my WeatherFlow Tempest station and then successfully upload them to OpenWeatherMap.org.
A cron job is used to run the second script every 10 minutes.
No additional weather software is needed.

Enjoy,
Kostas
