Hola!
I am in Spain, and just today found out the model of my AC (it's very difficult to access). It's a Fujitsu General ARH 45 LUAN split system.
I was thinking of getting a smart controller for it, but so far I have been unsuccessful figuring out if there is a smart solution for this AC - native or third party - so I would be grateful for any tips and ideas.
EDIT: The AC is a duct type system with just a wall-mounted control (no IR receiver).
I don't know anything about that specific model, but one option for most mini split and window AC units is to get a smart IR blaster.
This system doesn't have an AC receiver - it's a duct type system and only has a wired wall-mounted panel. I edited my original post to add this detail :) Thanks!
