Sync setup fails with unclear "unsupported protocol scheme" error

[mifarse]

When trying to configure using the example settings, an unclear error occurs:

sync_alex_zepp:
  from: zepp/xiaomi alex@gmail.com xiaomi-password
  to: garmin alex@gmail.com garmin-password

Error message:

2025/08/18 11:33:27 scaleconnect version 0.3.0
2025/08/18 11:33:27 sync_alex_zepp: load data error: Get "": unsupported protocol scheme ""

Expected behavior: logs should show the connection attempt and the result of authentication (success or failure), not just the unclear error.

Yes, you're right. I spent most of my energy on the functionality.

Hi,
I have the same problem with xiaomi home (scale s400). Probably xiaomi account login requires 2FA?

[AlexxIT]

Yes. You right. It's about 2FA. Do you have Home Assistant?

[nemetila]

Yes, I have HA.

[AlexxIT]

Well.

1. You can install and setup this integration: https://github.com/AlexxIT/XiaomiGateway3
2. Goto /config/.storage/core.config_entries and copy token
3. Paste token to scaleconnect.json (change your username):

{"xiaomi:alex@gmail.com":"...token..."}

[nemetila]

Thank you. It is OK now.

When I have time, I will transfer this functionality to scaleconnect. But the problem is that the app doesn't have a GUI.

I have tried the steps mentioned here, but I get a 401. I really dont know how to troubleshoot further.

scaleconnect-1  | 2025/10/06 12:10:23 scaleconnect version 0.4.1
scaleconnect-1  | 2025/10/06 12:10:25 sync_henrik_xiaomihome: load data error: 401 Unauthorized

scaleconnect.yaml

sync_henrik_xiaomihome:
  from: xiaomihome henrik@mydomain.se MySupersecretpassword de yunmai.scales.ms104
  to: csv henrik_xiaomihome.csv
  expr:
    Weight: 'User == "Henrik" ? Weight : 0'

scaleconnect.json
{"xiaomi:henrik@mydomain.se":"1234567890abcdef1234567890abcdef"}

Edit - really having trouble formatting the file contents in this comment. But I beleive the yaml is correctly indented

[henrikmaurin]

Ok, Now I found the problem.
By reinstalling XiaomiGateway3 integration I found out I had been looking at the wrong config line/token
the correct token is much longer than in my example

[albertofralbe]

Well.

1. You can install and setup this integration: https://github.com/AlexxIT/XiaomiGateway3
2. Goto /config/.storage/core.config_entries and copy token
3. Paste token to scaleconnect.json (change your username):

{"xiaomi:alex@gmail.com":"...token..."}

Done all of this but still getting the original error, how can I fix it?

[AlexxIT]

The file name may be invalid. Or the contents. Or the token may be invalid. It must be very long with colons inside.

[albertofralbe]

Solved, for anyone else who may have done the same mistake:
In order to find the correct token, you need to search for "xiaomi" inside the /config/.storage/core.config_entries file.

Thanks @AlexxIT

Hello @AlexxIT,
I have the same error, but it looks like it is not about 2FA, as I don't have it

Scale: Mi Body Composition Scale 2 (XMTZC05HM)

Error in logs

2025/10/26 11:28:39 scaleconnect version 0.4.1
2025/10/26 11:28:40 sync_zepp: load data error: Get "": unsupported protocol scheme ""

scaleconnect.yaml

sync_zepp:
  from: zepp/xiaomi zepp@email.com password
  to: csv zepp.csv

P.s.

• I have ~500 records on this Zepp account
• This Zepp account is not connected to the Xiaomi account
• I tested your app on another Zepp account with just 20 records, and it's working fine

Can you please add a debug log level?
