Does wired port only DHCP on initial boot?

I configured a HM for my brother and had it hooked to my wifi to get the servo configured. When he plugs it into his network (wired) it didn't DHCP to give him a chance to configure for his WIFI.

Is this expected? Does it only DHCP if a wifi isn't setup?

thanks,
david

Did he try going to "heatermeter.com/devices" this should show him the the HM, if it did get an IP address.
I always set my IP address as static so I can reach it form outside my network with port forwarding.
