I've fruitlessly been googling for a remote control system which can control hidden centralised devices by RF - this part is easy enough, but I want 3 or 4 handsets stationed in different rooms to be able to control the RF receiver.

Does such a system exist?

I've looked at the iRule system which is effective and cost effective but I think a hard button remote control system is the way to go, but i dont want the expense of going for an automation system like control 4.
