Providing credentials via environment variables

You can use the following environment variables for providing the Garmin and/or Trainerroad credentials:

• GARMIN_USERNAME
• GARMIN_PASSWORD
• TRAINERROAD_USERNAME
• TRAINERROAD_PASSWORD

The CLI also uses python-dotenv to populate the variables above. Therefore setting the environment variables has the same effect as placing the variables in a .env file in the working directory.

Providing credentials via secrets files

You can also populate the following 'secrets' files to provide the Garmin and/or Trainerroad credentials:

• /run/secrets/garmin_username
• /run/secrets/garmin_password
• /run/secrets/trainerroad_username
• /run/secrets/trainerroad_password

Secrets are useful in an orchestrated container context — see the Docker Swarm or Rancher docs for more information on how to securely inject secrets into a container.

Order of priority for credentials

In the case of credentials being available via multiple means (e.g. environment variables and secrets files), the order of resolution for determining which credentials to use is as follows, with later methods overriding credentials supplied by an earlier method:

1. Read secrets file(s)
2. Read environment variable(s), variables set explicitly take precedence over values from a .env file.
3. Use command invocation argument(s)

Obtaining Withings Authorization Code

When running for a very first time, you need to obtain Withings authorization:

$ withings-sync -f 2019-01-25 -v
Can't read config file config/withings_user.json
User interaction needed to get Authentification Code from Withings!

Open the following URL in your web browser and copy back the token. You will have *30 seconds* before the token expires. HURRY UP!
(This is one-time activity)

https://account.withings.com/oauth2_user/authorize2?response_type=code&client_id=183e03e1f363110b3551f96765c98c10e8f1aa647a37067a1cb64bbbaf491626&state=OK&scope=user.metrics&redirect_uri=https://wieloryb.uk.to/withings/withings.html&

Token :

You need to visit the URL listed by the script and then - copy Authentification Code back to the prompt.

This is one-time activity and it will not be needed to repeat.

Tips

Garmin SSO errors

Some users reported errors raised by the Garmin SSO login:

withings_sync.garmin.APIException: SSO error 401

or

withings_sync.garmin.APIException: SSO error 403

These errors are raised if a user tries to login too frequently. E.g. by running the script every 10 minutes.

We recommend to run the script around 8-10 times per day (every 2-3 hours).

Docker

$ docker pull ghcr.io/jaroslawhartman/withings-sync:master

First start to ensure the script can start successfully:

Obtaining Withings authorisation:

$ docker run -v $HOME:/root --interactive --tty --name withings ghcr.io/jaroslawhartman/withings-sync:master --garmin-username=<username> --garmin-password=<password>

Can't read config file config/withings_user.json

Token : <token>
Withings: Get Access Token
Withings: Refresh Access Token
Withings: Get Measurements
   Measurements received
JaHa.WAW.PL
Garmin Connect User Name: JaHa.WAW.PL
Fit file uploaded to Garmin Connect

And for subsequent runs:

$ docker start -i withings
Withings: Refresh Access Token
Withings: Get Measurements
   Measurements received
JaHa.WAW.PL
Garmin Connect User Name: JaHa.WAW.PL
Fit file uploaded to Garmin Connect

Garmin auth

You can configure the location of the garmin session file with the variabe GARMIN_SESSION.

Run a periodic Kubernetes job

Edit the credentials in contrib/k8s-job.yaml and run:

$ kubectl apply -f contrib/k8s-job.yaml

For advanced users - registering own Withings application

The script has been registered as a Withings application and got assigned Client ID and Consumer Secret. If you wish to create your own application - feel free!

• First you need a Withings account. Sign up here.
• Then you need a Withings developer app registered. Create your app here.

Note, registering it is quite cumbersome, as you need to have a callback URL and an Icon. Anyway, when done, you should have the following identifiers:

Identfier	Example
Client ID	183e03.................765c98c10e8f1aa647a37067a1......baf491626
Consumer Secret	a75d65.................4c16719ef7bd69fa7c5d3fd0ea......ed48f1765
Callback URI	https://jhartman.pl/withings/notify

Configure them in config/withings_app.json, for example:

{
    "callback_url": "https://wieloryb.uk.to/withings/withings.html",
    "client_id": "183e0******0b3551f96765c98c1******b64bbbaf491626",
    "consumer_secret": "a75d65******1df1514c16719ef7bd69fa7*****2e2b0ed48f1765"
}

For the callback URL you will need to setup a webserver hosting contrib/withings.html.

To do this in a Docker installation, you can use the environment variable WITHINGS_APP to point to a mounted withings_app.json

Example docker-compose:

  withings-sync:
    container_name: withings-sync
    image: ghcr.io/jaroslawhartman/withings-sync:latest
    volumes:
      - "withings-sync:/root"
      - "/etc/localtime:/etc/localtime:ro"
    environment:
      WITHINGS_APP: /root/withings_app.json
(...)

You can then add the app-config in withings-sync/withings_app.json

Run a periodic docker-compose cronjob

We take the official docker image and override the entrypoint to crond.

If you have completed the initial setup (withings_user.json created and working), you can create the following config

version: "3.8"
services:
  withings-sync:
    container_name: withings-sync
    image: ghcr.io/jaroslawhartman/withings-sync:master
    volumes:
      - "${VOLUME_PATH}/withings-sync:/root" 
      - /etc/localtime:/etc/localtime:ro
    environment:
      - TZ=${TIME_ZONE}
    entrypoint: "/root/entrypoint.sh"

The entrypoint.sh will then register the cronjob. For example:

#!/bin/sh
echo "$(( $RANDOM % 59 +0 )) */3 * * * withings-sync --gu garmin-username --gp 'mypassword' -v | tee -a /root/withings-sync.log" > /etc/crontabs/root
crond -f -l 6 -L /dev/stdout

This will run the job every 3 hours (at a random minute) and writing the output to console and the /root/withings-sync.log.

Release

Release works via the GitHub Draft a new Release function. Keep in mind to bump the version key in setup.py.

Docker Image

An image is created magically by GitHub Action and published to ghcr.

pypi

You'll find a script to create and upload a release to pypi here contrib/do_release.sh. It requires twine. This needs the permission on the pypi-project.
