darksky-influxdb

Docker image which logs weather information from DarkSky.net to InfluxDB.

DarkSky key

A DarkSky api key can be requested here: https://darksky.net/dev. This key needs to be provided to the docker image as an environment variable.

You get 1000 requests per day for free. Enough to use for your personal weather logger.

Usage

An example of using this in docker-compose can be found here.

Run it once:

docker run -rm -it \
    -e DARKSKY_KEY=<your-darksky-key> \
    -e INFLUXDB_HOST=influxdb.myhost.io \
    -e INFLUXDB_PORT=8086 \
    -e INFLUXDB_DATABASE=weather \
    erwinsteffens/darksky-influxdb:latest

Run it every 10 seconds:

docker run -rm -it \
    -e DARKSKY_KEY=<your-darksky-key> \
    -e CRON="*\10 * * * * *" \
    -e INFLUXDB_HOST=influxdb.myhost.io \
    -e INFLUXDB_PORT=8086 \
    -e INFLUXDB_DATABASE=weather \
    erwinsteffens/darksky-influxdb:latest

Query the weather data from your InfluxDB instance. For example show average temperature for the last 7 days:

SELECT MEAN("temperature") FROM weather WHERE time > now() - 7d GROUP BY time(1d)
