KeyError: 'settings.onOffStatus' when calling climate.set_hvac_mode with version v0.14.0

[acalantoni]

Hello Andre0512 (or relevant developers),

I am experiencing an issue with the Haier hOn integration, version v0.14.0, when trying to control my Haier air conditioner. When I attempt to set the HVAC mode (e.g., turn off the AC or change to cool/heat), I receive a KeyError: 'settings.onOffStatus' error.

Environment:

Haier hOn Integration Version: v0.14.0 (as shown in the attached screenshot from HACS) Home Assistant Core Version: [2025.5.1] Haier Air Conditioner Model: [AB35S2SC2FA-1] Haier Air Conditioner Firmware Version: [5.15.0] Problem Description: The climate entity for my Haier AC (climate.ced_server_condizionatore) appears correctly in Home Assistant with all standard attributes and modes. However, any attempt to change the HVAC mode via Home Assistant (e.g., calling climate.set_hvac_mode service with hvac_mode: 'off' or any other mode) results in an error.

Steps to Reproduce:

Navigate to Developer Tools > Services in Home Assistant. Call the climate.set_hvac_mode service. Select the Haier AC entity (e.g., climate.ced_server_condizionatore). Set an hvac_mode (e.g., off, cool). The service call fails, and the error below appears in the logs. Error Log:

This might be due to an API change, a specific behavior of my AC model/firmware, or an issue in how the settings are populated.

Thank you for your work on this integration and for any help you can provide.

with my AS25S2SF1FA-W and Firmware Version 5.15.0 I can't turn it off and I get an error that hvac modу 0 is not supported

[fatshotty]

I have the same error, too: hvac mod 0 is not supported

@Monoboy4ik thanks, i already saw that fix, but it is only for 'off' command. I mean: i have 2 custom programs on my ac; in HA I see those programs, but they are not selectable. If I select one of those program, I got the same previous error :/

I think it is not an "HA integration" issue; i think these errors come from pyhOn, so the library which this HA integration depends to

I have the same problem. "Allowed values: ['2', '4', '5', '6', '8'] But was: 0" I have a script where I call a popular program from Hon.

mode: single sequence:

• service: select.select_option target: entity_id: select.obyvaci_pokoj_program data: option: "chlad26"

Error Chyba: Allowed values: ['2', '4', '5', '6', '8'] But was: 0

params:domain: select service: select_option service_data:option: chlad26 entity_id:

• select.obyvaci_pokoj_program target: entity_id:
• select.obyvaci_pokoj_program running_script: false

Any solution?

Thx
