Unless they changed something, you are SOL.
I tried sniffing the packets in and out of the hub on wireshark but it all seemed too obfuscated and not worth the effort
switched over to esp8266 based sonoffs and bulbs and flashed them to Tasmota.
And yes, that’s the ir blaster I am talking about.
Flashing it is pretty easy but you do need to open it up and solder 4 wires on to the board.
Once you’ve done that, you can follow the handy guide on the tasmota github…
It does work extremely well and configured aircons show up as a proper hvac thermostat on HA as well as homekit
On a side note, for switches and plugs ( or light bulbs) , you are much better off with esp8266 devices than tasmota.
Also look up Tuya-convert on github if soldering is not your thing
