Yeah, I’ve been doing the same thing for a while now. I use the app https://mac.eltima.com/iphone-remote-control-app/ it connects to my smart TV, speakers, and even my air conditioner. It took a few minutes to set everything up, but once it’s done, it just works. The best part is not needing to juggle five different remotes. Plus, I can control everything from another room, which is super handy when I forget to turn something off.
