Two IPs on the same Hub

[marktheknife]

I agree with @rlithgow. Configure a DHCP reservation in your router’s settings page, and keep your Hubitat hub in its default DHCP mode (or push that button on the bottom to reset back to DHCP).

Dont set a static IP address on the hub’s network settings page unless you’re absolutely sure you know what you’re doing.

This post from a while back might help explain the difference between the two terms DHCP reservation and static IP address assignment.

This blog post explains the concept of DHCP reservations in pretty plain language, which you might find helpful: Note that it contrasts DHCP reservation with static IP address assignment. But it’s important to understand all this is on your Local Area Network (LAN). AT&T would only charge you money to set your public IP address to static. Also called your WAN (Wide Area Network) IP address. That’s for a totally different use case, as @bertabcd1234 explained.
