It would be essential for me to have this integration.
I have tried the different options available in different forums, including one published in this same post, but the firmware blocking access via LAN makes none of them functional.
The only way that works in my case is to use IR with a Wi-Fi device like those from Broadlink, Sesibo and others that use zwave (I have not tried this but it is the same, it only changes the device-intermediary->HA communication). But this solution presents different problems such as not having the status of the AC.
