I think there is some misunderstanding of how the integration works:
- Tokens are tied to your SmartThings or Samsung account. You can use any valid token under the same account to setup the integration or clean it up using the removal utility. If you didn’t retain the token when created (which the instructions indicated to do), go create another one temporarily to use with the remove utility.
- Deleting tokens does not remove the integration. It just removes access to your ST/Samsung account.
- This is a Home Assistant integration, not Hass.io. There are no local files you can delete to solve OP’s problem.
- The removal utility is what you need to use to remove the orphaned apps in Automations and Marketplace. It only requires a valid token and can be ran anywhere, as it uses the SmartThings cloud API. Note that in Home Assistant v0.90 (releasing 3/20), it will remove the apps when the integration is removed, but this requires a functioning integration.
