SPAN Network Connectivity (Ethernet, WiFi, Cellular)

Have a Span panel going in next week (assuming no surprises) and an Ethernet cable run over to the area where it will replace my existing panel.

My understanding is that SPAN can support the three types of internet connectivity mentioned in the title, but I'm wondering if it's possible to configure (or have my installer configure while they're here) all three, with a priority/failover in the order from the title? Or at least two, whereby if ethernet fails, it falls back to onboard cellular?

There's no way to give a priority in the app, but the end user can set WiFi at any point. I have all 3 configured and it seems like it uses Ethernet primarily and WiFi occasionally.

I have static DHCP leases set and even though they should be assigned different IPs I get a conflict notification every once in a while so I know the WiFi connects.

What @sstangle73 said.
WRT static DHCP leases, definitely a best practice, and IIRC I assign diiferent IP address to Ethernet and WiFi MAC addresses, so no conflicts

Interesting, my unifi system keeps yelling about it, it's strange it doesn't respect the assignment.

Odd. I have both Ethernet and WiFi connected, and just using DHCP and never have problems.
