Deconz on a Separate Server?

I’m trying to figure out how I can set up DIYHue to look for Deconz on a separate server. For example, if you’re doing an Open-WRT installation, I assume you’re not running Deconz in Open-WRT also. So, how would you connect to Deconz to get your other Zigbee devices? Or, do you have to run DIYHue on the same hardware as Deconz? Thanks!
