As a more general approach for making any air conditioner "smarter", there is a SmartIR integration [1] for Home Assistant. It requires an IR blaster and a configuration file that defines IR code sequences for every possible AC state (temperature + fan speed + swing + etc) that you might want to use. Many models are already configured or you can try a few models from the same manufacturer and sometimes the codes are similar enough that you'll find one that works.

Once it's set up you get a nice climate control in Home Assistant, the only drawback is that the state displayed in HA will go out of sync if you use the physical remote.
