HomeAssistant Addon aint working correctly with Garmin

[Phipseyy]

Description

Hey there, I just got to install the HomeAssistant addon and set it up according to the Configuration
I've enabled Garmin and set up my email / password
But with every export, it just fails:

2026-04-11 14:13:31.130 [Sync] Exporting to: garmin...

I also cannot really see where the addon saves my tokens etc
Tried another config but the addon wont fill / save the file properly

Running on a Raspi 5 with Homeassistant OS

Steps to Reproduce

1. Add Addon
2. Enable and Enter Garmin Infos
3. Start Addon
4. Step on Scale as soon as it's ready
5. Wait for export to fail

Hi @Phipseyy, thanks for the report! You spotted a real bug.

What was happening

The HA Add-on wrote a Garmin section into the generated config.yaml with token_dir: /data/garmin-tokens and created that directory, but never ran the authentication step. The Node app then launched, called garmin_upload.py, which tried to load the token files that had never been created — exactly the error in your logs:

[Errno 2] No such file or directory: '/data/garmin-tokens/oauth1_token.json'

Normal Docker usage has a separate docker run ... setup command that runs the Python setup_garmin.py script to produce the tokens. In an HA Add-on there's no equivalent step, so the tokens simply never existed.

Fix (v1.7.5)

On start, the add-on now:

1. Checks whether Garmin is enabled and whether /data/garmin-tokens/oauth1_token.json already exists.
2. If tokens are missing, runs python3 garmin-scripts/setup_garmin.py --from-config /app/config.yaml with your credentials. Tokens land in /data/garmin-tokens/ and persist across restarts.
3. If that fails (for example your Garmin account uses 2FA, which can't be prompted for inside an add-on), logs a clear message pointing at the manual workaround and keeps running so MQTT and other exporters still work.

If you use MFA

Release notes and the updated DOCS.md describe it, but the short version:

1. On a laptop, clone the repo and run python3 garmin-scripts/setup_garmin.py. Enter email, password, and MFA code.
2. Copy the resulting oauth1_token.json and oauth2_token.json into /share/ble-scale-sync/garmin-tokens/ on your HA host (Samba or File editor add-on makes this easy).
3. Restart the BLE Scale Sync add-on. It detects the pre-generated tokens and imports them into /data/garmin-tokens/.

How to get the fix

Release: https://github.com/KristianP26/ble-scale-sync/releases/tag/v1.7.5

Update the add-on through the Supervisor UI once v1.7.5 appears (should take a few minutes after the release is published). Restart it and check the logs for either Garmin authentication successful, tokens saved to /data/garmin-tokens or the MFA warning.

Let me know how it goes.
