DarkSky RTPS Node

RTPS bridge for DarkSky API using eProsima's FastRTPS.

What happened to Weather Underground?

Turns out that Weather Underground will be shutting down it's API service as of 12/31/2018, so I decided to use DarkSky instead.

Requirements

These variables can be set as either Docker secrets, or just as environment variables.

Variable Name	Description
DARKSKY_KEY	API key that you get by signing up on DarkSky.
DARKSKY_LATITUDE	The latitude of the location you would like to publish.
DARKSKY_LONGITUDE	The longitude of the location you would like to publish.
DARKSKY_POLLING_RATE	Rate (in ms) at which DarkSky should be polled, and data published. With the calling rate limit, the default is set to 90 secs.
