I rebooted yesterday so route changes are low. I'll have to pull off switch plates for exact model numbers unless certain device info tells you the. model.
Ohhhh, this totally makes sense! Yes I do. It's the dead front porch light switch haha. I bet it routed through that and is now confused. The hallway switch is probably 15 feet away, line of sight.
Not only is it confused but it having a hard time finding a good route. It must not be getting acks back fast enough or something so it keeps pining the network looking for better routes.
Normally pulling a device out the mesh would self-heal and figure it out eventually, but it looks like the lock was left stranded with no good routes to the hub.
If you get a repeater closer to that lock or just pull the batteries on it for now, the whole mesh will probably be happier.
So still not sure what it was, but the network seems to be improving. I have replaced one of the bad switches, now resulting in a third ghost node..... Now I need to get rid of all these ghost nodes.
