slack-health-bot: Slack notifications for limited Withings and Fitbit data

Pushes messages to a pre-selected Slack channel, when users log new weight data in Withings or new sleep or activity data in Fitbit.

Configuration

• Create an application in the Withings developer dashboard.
• Create an application in the Fitbit developer dashboard.
• Create an application on Slack, with a webhook to post messages to a specific channel.
• Copy the .env.template file to .env, and modify the values.

Retrieve the docker image

Retrieve the image:

docker pull ghcr.io/caarmen/slack-health-bot:latest

Run the docker image

Create a folder on the host where the database will be saved: /path/to/data/.

Run the docker image.

docker run --detach --publish 8000:8000 -v `pwd`/.env:/app/.env -v /path/to/data/:/tmp/data ghcr.io/caarmen/slack-health-bot

Using the application

Withings

• Open the following url in a browser: http://your-server/v1/withings-authorization/your-slack-alias
  • Change your-server with the address on which the server is available.
  • Change your-slack-alias with your slack username.
• Authorize the app in the Withings screen.
• Log a new weight measurement in your Withings account.
  • After a couple of minutes, you should see a message in the configured slack channel saying:

    New weight from @your-slack-alias: XX kg

Forcing a measurement to be pushed to slack

You can force a measurement to be posted to slack, by simulating Withings calling the webhook:

curl --location 'http://your-server/withings-notification-webhook/' \
--form 'userid="1234567"' \
--form 'startdate="1680377444"' \
--form 'enddate="1682969444"'

Fitbit

• Open the following url in a browser: http://your-server/v1/fitbit-authorization/your-slack-alias
  • Change your-server with the address on which the server is available.
  • Change your-slack-alias with your slack username.
• Authorize the app in the Fitbit screen.
• Log a new sleep measurement or activity in your Fitbit account.
  • After the polling period (if polling is enabled), or after a the webhook is called, you should see a message in the configured slack channel saying (for the sleep example):

    New sleep from @your-slack-alias:

    • Went to bed at 22:17

    • Woke up at 7:59

    • Total sleep: 8h 31m

    • Awake: 1h 11m

    • Score: 96

You can find your userid in the database file:

sqlite3 -header -column /path/to/slackhealthbot.db \
  "select
     slack_alias,
     withings_users.oauth_userid as withings_userid,
     fitbit_users.oauth_userid as fitbit_userid
  from users
    left outer join withings_users on users.id = withings_users.user_id
    left outer join fitbit_users on users.id = fitbit_users.user_id;"
