I'm using the Samsung Smart Airconditioner App
According to comments in the MixRank link above this AC doesn't even work with Samsung's Smart Home system so I haven't tried that path.
The Smasung app is REALLY bad. It gets 1.5 stars in the play store: https://play.google.com/store/apps/details?id=com.samsung.rac
With Sensibo, I am not sure if intergration will remain possible after Sept 30 with Smartthing changing as it is, but it is still a great option. Here is a link: https://sensibo.com/products/sensibo-sky

Good luck!
