Setting remote Deconz gateway

Trying to get back in the HA saddle, it’s admittedly been a few years.

Anyway, when I last set deconz up there was a field to specify an IP for a remote deconz host. I have deconz running on a rpi3 that I’d like to connect to my server. However, I can’t figure out how to, or where to, assign the gateway with the new deconz integration.

Any guidance is appreciated!
