2FA has arrived, several bugs fixed (including disk wakeup), more languages

on GitHub

👉 Added

• added optional two-factor authentication support using authenticator app codes: trusted-device registration for UGOS accounts with 2FA enabled.
• added a separate Advanced settings step to the integration options flow.
• added new languages for setup & options flow: bg, ja (jp), ko, zh-Hans (cn), zh-Hant (cn), nl, pt, sv, da, nb (no), fi.

👉 Changed

• unified normal login and 2FA enrollment to use the same internal authentication mechanism.
• moved polling intervals and example-dashboard settings out of the main options page.
• updated all included translations for the revised options flow.
• skipped disabled entities when creating polling groups on startup.
• excluded endpoints that have returned a 404 HTTP error from active polling until next integration reload.

👉 Fixed

• stabilized entity IDs for the Fan Mode and Power Mode selects.
• fixed example-dashboard compatibility with newly created mode-select entities.
• fixed cache-pool and cache-disk key parsing.
• fixed incorrect assignment of cache disks to the wrong pool or cache device.
• fixed incorrect cache-device names, metadata, and device hierarchy caused by the parsing error.
• removed those S.M.A.R.T. entities introduced in v2026.08.1 that would prevent disk sleep.
• improved API error logging even when the returned error is empty.
• do not create show connections of all users entity if no backup job exists.
• only poll backup entities if a backup job exists (disks also did wake up from sleep here).

👉 Internal changes

• added _local_dev_overrides/ and make it work like in my other integrations.
• prevent API tokens and passwords from being exposed in debug and error logs.
• updated device hierarchy handling for Home Assistant 2026.9 by replacing the deprecated via_device implementation with via_device_id.

👉 Notes

• two-factor authentication currently supports authenticator app codes only, Email-based 2FA codes are not supported.
