WeeWX to InfluxDB

Allows for importing weather station data from WeeWX to InfluxDB v2.

Requirements

• Tested with a Raspberry pi 2, but should work on most other distros.
• WeeWX configured on this device.
• Either Docker or Python 3.7+ installed on this device.
• InfluxDB v2 installed on this or another device, and a bucket created in influxDB.

Setup

With Docker

Dependency: Docker installed.

1. Locate the weewx.sdb file, for example by running find / -name weewx.sdb
2. Download and run the Docker image: sudo docker run --name weewx-influx -v config.yaml:/app/config.yaml -v /var/lib/weewx/weewx.sdb:/var/lib/weewx/weewx.sdb vdbg/weewx-influx:latest
3. Copy template config file from image: sudo docker cp weewx-influx:/app/template.config.yaml config.yaml
4. Edit config.yaml by following the instructions in the file
5. Start the container again to verify the settings are correct: sudo docker start weewx-influx -i
6. Once the settings are finalized, Ctrl-C to stop the container, sudo docker container rm weewx-influx to delete it
7. Start the container with final settings:

sudo docker run \
  -d \
  --name weewx \
  -v /path_to_your/config.yaml:/app/config.yaml \
  -v /path_to_your/weewx.sdb:/var/lib/weewx/weewx.sdb \
  --memory=100m \
  --pull=always \
  --restart=always \
  vdbg/weewx-influx:latest

Without docker

Dependency: Python 3.7+ and pip3 installed. sudo apt-get install python3-pip if missing on raspbian.

1. Git clone and cd into directory
2. cp template.config.yaml config.yaml
3. Edit file config.yaml by following instructions in file
4. pip3 install -r requirements.txt
5. python3 main.py or ./main.py

Alternative

There's a good WeeWX plugin here

• pros: no delay to import (runs in WeeWX's main loop), more options for types of units.
• cons: missing records if InfluxDB is temporarily unreachable, no historical import capabilities.

Also, the alternative plugin works against Influx v1.8 vs. 2.x.
