Review on Enhance Home Automation with BroadLink RM4 Pro Sensor Cable: An Essential Addition for Smarter Control by Tommy Penn

I was hoping this would replace my defunct Harmony hub and remote, but so far the only thing it has consistently been able to do is turn my audio system on and off. I wanted him to control my fans but no luck and their learning function is useless. It doesn't work with the Apple TV and if I had done some research before buying on the spur of the moment (it was a Prime Day deal) I would have given up. He seems to have a long list of brands he endorses, but unless you live in Asia, you've probably never heard of them. I regret this purchase and will replace it with something working.
