I use a couple of boxes that when addressed initiate some relays. But they require a DMX address for each relay (e.g. one for Red, One for Green and so on). I'm looking for a box or system (Raspberry Pi. Arduino perhaps) where I can Decode the data being sent to a single DMX address and have that presented to 8 pins for actuating my relay system. So, if I send "16" to that address then pin 4 will go high (or low). Are there any commercial units that would do this?
