Sorry, something went wrong.
Secure-login Tapo cameras and hubs (observed on a C200 HW 1.0 / FW 1.3.17, and in the H200/H500 logs of python-kasa#1149, python-kasa#1341, python-kasa#1578 and python-kasa#1647) answer handshake1 with inner code -60502 when the supplied username is not the one accepted for secure login. The transport already handles this by falling back to the default username, but since the code was unknown to SmartErrorCode a "received unknown error code: -60502" warning was logged on every connection. The code is not documented by TP-Link nor by pytapo; the name is derived from testing, like BAD_USERNAME (-40411). The existing MockSslAesDevice.BAD_USER_RESP already returned -60502 and is extended to carry the encrypt_type/key/nonce fields seen on the C200 so the new test exercises the code path that emitted the warning. No change to the authentication flow.

LGTM, thanks @juherr! Please avoid unnecessary details in docstrings, check my inline comments. Could you also add a test for the piece that causes the missing coverage through this PR?

I would also shorten this.

Fix the issue with code coverage and those comments, then this is ready to go.
Sorry, something went wrong.
Shorten the test docstring and the mock comment as requested, and add a test sending an unknown inner error code so the warning branch of _get_response_inner_error() stays covered now that -60502 is known.

## [0.11.0](https://github.com/python-kasa/python-kasa/tree/0.11.0) (2026-10-04) [Full Changelog](0.10.2...0.11.0) **Release summary:** This is a huge and long overdue release, coming more than a year and a half after the previous one. Hopefully the next one follows sooner, as the TPAP transport (which did not make it into this release) is used more and more on newer devices. This release brings broader camera support, new modules for lights, vacuums and cameras, and many connectivity fixes for newer firmware versions. Some other highlights: - Improved Tapo camera support: login version 3, presets, wifi handling, last alert detection, and more robust authentication and discovery. - Selective room cleaning for robot vacuums. - Configurable light strip length via the new strip segment module, and an exposed light transition state change flag. - Basic HomeKit module for Kasa (iot) devices. - Energy monitoring V2 support (S515D). - Better hub and thermostat state reporting (hold, summer mode, low battery). - Connection fixes for newer Tapo firmware and older SSL devices, plus KLAP v2 for iot devices. - More resilient time handling, with failover and UTC fallback for iot devices. - Python 3.14 is now supported. - Inclusion of fixtures for 29 devices or firmware versions, including the Tapo C460, C200 and C101 cameras and the KH100 hub with KE100/KE110 thermostats. **Thank you to all contributors!** A big thank you to everyone who contributed to this release, whether through code, device fixtures, bug reports or testing. Special thanks to @ZeliardM for a huge effort on both features and project maintenance, including but not limited to: - Features like the HomeKit module for iot devices, iot time module failover, wifi handling and credential improvements for cameras, Tapo login version 3, and V2 energy monitoring for S515D. - A lot of necessary maintenance work including type annotations and cleanups throughout the test suite, modernized docstrings, CI hardening with SHA-pinned actions, and many bug fixes. This helps us to keep the library maintainable and open to new contributions. A warm welcome to our new contributors, with special thanks to those who contributed improvements and fixes: - @alams154: discovery on port 20004 - @bluntman001: iot device classification fix - @bm1549: KLAP v2 transport for iot devices - @darylldelfin: cipher support for newer Tapo firmware - @davidefiocco: vacuum mop water level fix - @epg-pers: selective room cleaning for vacuums - @freeKC: camera discovery and authentication fixes - @gpongelli: extended camera detection - @Ikstar: KL420 color temperature range - @juherr: last alert detection module for cameras, camera error codes and a C200 fixture - @kad: SSL connections to older devices - @KaloyanNaumov: multi-request timeout handling - @loganrosen: KL400L5 color temperature range - @markvanpraet: Tapo C460 support and camera battery fix - @monteccarlos: iot timezone mapping fix - @mrwogu: preset support for Tapo cameras - @nopoz: strip segment module, light transition flag and credentials hash fix - @tk1475: UTC fallback for unset iot device clocks - @wh1t3f1r3: non-retryable network error handling Thanks also to our new contributors who provided device fixtures to help future development efforts: @emanueleg, @fantandrea, @HarryPehkonen, @ijaron, @Krotu, @LostLuma, @mjbohr and @TheLinuxGuy. **This release in numbers:** -

Symptom
On secure-login Tapo cameras and hubs, every connection logs:
The device answers handshake1 with {"error_code": -40401, "result": {"data": {"code": -60502, ...}}} when the username sent is not the one accepted for secure login (e.g. the cloud email on a Tapo C200 HW 1.0 / FW 1.3.17). SslAesTransport already handles this correctly by falling back to the default admin username, which then succeeds — but because -60502 is not a SmartErrorCode member, _get_response_inner_error() logs the warning on a perfectly normal flow.
