I recently deployed https://github.com/jaroslawhartman/withings-sync to sync my Withings scale to my Garmin account. Here’s a quick Powershell script I whipped up that runs via Scheduled Tasks on Windows and uses a Discord Webhook to notify you of its progress:

Install the PSDiscord powershell module. Set $hookUrl with your Discord Webhook URL. Setup your path to the Python withings-sync executable in the $wsPath variable, then call the withings-sync function from Powershell after initializing your Withings token with withings-sync manually, as per the github instructions (pass your Garmin credentials as the $username and $password parameters). The script will auto-retry up to $maxTries times every $hoursToPause.
Edited 2021-09-21: removed some code from the Execute-Command function that could cause a deadlock when Garmin spits out its 403 error and changed the order of the if/else statements slightly. Cheers!
