Hey there!
I’m struggling with the add-on installation 
When I try to install it, after a few minutes I get Out of memory error. Then if I restart, supervisor can’t start and I have to reinstall the OS
I’m using a raspberry pi 3b+, any ideas? Thanks
I hope this can provide a value: New custom integration to control Tornado (aux cloud) aircon
I also have an AC AUX Q-SMART PREMIUM, and I’m experiencing the same problem as you. 
Have you made any progress with it? Maybe you’ve found a solution?
Hi! for anyone interested I created version of this integration that doesn’t require MQTT or Add Ons. It’s just a Home Assistant custom component. It can be installed via HACS or by copying to the config/custom_components folder.
This is the link: GitHub - maxm/broadlink-ac: Broadlink AC Home Assistant Custom Component
It’s using the same protocol originally implemented by https://github.com/liaan/broadlink_ac/ so if that addon worked for you this should work too.
