If you live in a house with no central climate control, or if you're making an expansion to your house and it's impossible to get a ducted system in place, a ductless setup may be your only hope.
Setup It takes less than five minutes to get the Sky mounted, turned on, and set up; Synchronizes with the AC's remote You don't need to hide or stop using your regular AC remote. Sky picks up the signals coming from it and synchronizes its state accordingly.
No manual learning mode If your AC's remote isn't supported; you can't teach the Sky its commands manually. Update: Sensibo tells us this is due to the intricacies of AC remotes; but its customer support can reach out to you and add any remote in about 10 minutes.
