jet mode disables after 10 seconds

[joeblack2k]

Hi, I installed the hardware yesterday and everything is working well. However, when I enable Jet Mode using the LG ThinQ app, the air conditioner turns on briefly, then turns off again after about 10 seconds and the temperature resets to 18°C.

Is this a known issue with the ESPHome integration or the hardware setup?
Is there any way to keep Jet Mode enabled longer, or is this behavior expected?

Thanks in advance for any help!

LG Airco: S3-M09JA2PA

-EDIT-
hmm the code does specify power_heavy a few times.. i wonder if it just doesnt detect that i have this feature

Yeah jet mode is not supported yet. See also #38.

ah thanks, is that something you are still working on or is it something thats perhaps not even possible at all

I traced and fixed the Jet/Power fan-mode issue from my live LG Airco ESP32 setup.

Root cause: the LG protocol uses fan value 7 for Jet/Power mode. The component rejected that as an unexpected fan mode, so the climate state stayed on the previous normal fan mode. On the next status send the controller wrote that normal fan mode, usually medium, back to the AC and Jet mode dropped out after a few seconds.

Draft PR with the fix:
#169

The fix adds Jet as a custom ESPHome climate fan mode, maps incoming LG protocol fan value 7 to it, and sends fan value 7 again while Jet is active.

Validation from my setup:

received C8.E2... / C8.E3... before the fix -> unexpected fan mode from AC (7)
set fan_mode: Jet via Home Assistant after the fix
sent A8.E3... / A8.E2...
received C8.E3... back from the AC
Jet stayed active for more than one minute
no more unexpected fan mode from AC (7) log entries
