I think maybe you are talking about a different device. Are you talking about a Zigbee Wifi gateway possibly? I am talking about a zigbee controller dongle that plugs directly into usb, this one for example. You run Zigbee2MQTT on the pi (or whatever it is plugged into). Friendly names and MQTT broker address are configured via its web interface. No wifi to configure for the dongle.
So do I. The zigbee nodes have problems I think, and don't really add anything.
