Our ceiling lamps and mini-split air conditioners are all IR remote controlled, so I just got a couple of IR blasters and set them up with Homebridge, so I can control the aircon/lights/TV with my iPhone or Apple Watch. If the smart stuff breaks down, I can just throw away the IR blasters and everything returns to how it was before. The only negative is since IR is one-way, you can't see the current status of things after you've manipulated it with a manual control.
