Fiber internet with cellular fail over

Hi all,
I am setting up an Netgear LB1120 using the EIOTclub sim.
What i want to do is have the LB1120 stay offline until HA detects that the fiber is down.
Then HA will bring up the LB1120 for internet service. Then once fiber is back up then HA disconnect the LB1120.

Is this possible.

Thanks James

HA could also brew a fresh cup of coffee… The problem (or solution) is not so much within Home Assistant, but plain (ip/tcp) networking and gateway fail-over. How is any device going to know what the new gateway is?

I’ve got a mobile fail-over, I use a pfsense router to monitor the WAN gateway and if it fails it switches to the “mobile” gateway. Multiple WAN Connections — Load Balancing and Failover with Gateway Groups | pfSense Documentation

Thanks for the reply, I’ll give pfsense a try.
