"Receive Loop Has Terminated" and "Unrecognised HVAC Mode of True Ignored" on Hyundai AC

[doctordarko]

Description

Hyundai Inverter Smart Split System Air Conditioner with product id hrzr8mr0mtgfwwri matches fisher_summer_air_conditioner with quality of 101%.

Unfortunately, there are tons of repeated errors that lead to the device becoming unknown at seemingly random intervals.

fisher_summer_air_conditioner.yaml/climate: Unrecognised HVAC Mode of True ignored (506 occurrences)

From here the device eventually fails with the following error: Bedroom AC receive loop has terminated

Interestingly, the device can still be turned on and off by selecting mode, despite it being unknown, but no other button or function works. Also, operating the AC with hardware remote brings the integration back to life and all buttons and modes functioning, until it fails again soon after.

Reloading the integration or restarting HA breaks the integration, if it was working at the time.

Please let me know if there is any extra data I can provide?

Attached is the debug log of freshly reloaded integration, pressing Cool on the mode selector to turn the AC on, then pressing Eco on the physical remote. Hopefully that gives you enough info to uncover what is happening. Thanks!

Confirmation

• I am sure this is a bug or improvement, that is well enough described that it can be implemented.

• This report is for tuya-local, not for localtuya.

• If this is for a specific device, the device config filename is mentioned above, or diagnostics are included.

• Log messages or diagnostics relevant to the issue are included.

• This is not requesting addition of a new device.

[make-all]

The device is not reporting its state. I doubr this device can every work reliably using the local protocol,

Is there anything else I can provide to verify this? With label device improvement, it makes me think there is a glimmer of hope. Thanks for amazing work!
