I'm sure this question has been asked a thousand times, but I can't seem to find an answer.

My parents want to have 2 remotes for their TV room. I've set them up with 2 Logitech Harmony 520s, but they have trouble with the activities not syncing up. I've told them to cover the emitter and select the same activity as the other remote, but they never remember to do it, then get frustrated because the remotes don't do what they want.

I need remotes that will communicate with each other. I know the Logitech base systems will only pair with one remote for reasons only Logitech understands, and my parents aren't ready to use smartphones yet.

Are there any systems that will accept multiple remotes? Anything under $200?

Thanks!
