This is a simple tool written in C++ listen to a weather station for weather data and writes it to an InfluxDB time series database for further analysis (e.g. in Grafana).

I use it with my Bresser 7-in-1 ClearView weather station and redirect traffic that is meant for a cloud service to this tool. The following description gives a brief overview over the necessary steps:

The Bresser 7-in-1 ClearView weather station supports uploading data to some cloud services like Weathercloud and Weather Underground, but unfortunately doesn't offer an API that allows querying from inside the local network. So instead, you need to configure your own local server as the cloud server in the Bresser configuration. In order to do this:

1. Switch the weather station to Access Point mode
2. Connect to the weather station WIFI and point your browser to the admin page at 192.168.1.1
3. Enter the address of your local server as destination server for the weather station
4. Submit the configuration, the weather station will automatically switch back to normal mode

Note that Bresser weather stations can only send traffic to port 80 of a server, so never mind trying to specify a different port. I am using a transparent proxy redirect in Apache to forward traffic to the weather exporter tool listening on a different port (see below).

Very straightforward. Create the Influx database, configure listen address and Influx parameters in the weather_exporter.yml file, and start weather exporter with

weather_exporter weather_exporter.yml

It'll automatically start to listen on the port and interface configured in the file. If you are not running a webserver on port 80 already, you can simply use port 80, run as root, and you're done. If you prefer running on a different port, or not as a privileged user, continue to next section to configure Apache to redirect weather traffic sent by the station.

If you're already running Apache on port 80 (like most servers will do), you need to redirect traffic from the weather station to the weather exporter tool. I use the following statement in the apache configuration, assuming your service is listening on IP 192.168.100.55 and port 41001:

ProxyPass "/weatherstation/updateweatherstation.php" "http://192.168.100.55:41001/post"

The tool only parses the query arguments and ignores the rest of the call URL, so it doesn't really matter what path you specify.

You can use the weather-exporter.service file provided in the repository to configure the weather exporter to run as a service and start automatically on boot. Modify the file as needed (especially user, path to binary and path to config). copy to /etc/systemd/system, and test with

service start weather-exporter

If it works, you can enable automatic start as usual with

systemctl enable weather-exporter
