Great that we are making progress and thanks for the debugging log.
It looks like Daikin are not consistent in the approach for fan direction, and I had a typo in the code that caused one of the errors.
Based on the logging this should now correctly set the two new device states fan_direction_left_right (and _up_down) based on how they are set.
I also added two actions to set the sate "Set Fan Direction Alira - Up/Down" and "Set Fan Direction Alira - Left/Right" that should work but I cannot test if the call is correct, it was an educated guess.
If you would like the device to report those additional modes/states then if you can post me a similar debug log with the comfort air flow, flash streaming and mould proof options set and we can see if it is reporting and if we can figure out how it is reported.
The API documentation is sketchy to say the least and they don't seem to be too consistent between the device types.
The latest version incorporating those fixes is
