I think the simplest answer is - have at least a few friends or relatives that are tech savvy enough to help your spouse or whoever figure things out. Our house is a rube goldberg machine of IoT devices, VLANs, and servers with VMs and other junk. No way I expect my wife to deal with any of that. But she does have access to a very simple, password protected file, that she can share with my father in law or one of a few friends of mine that are capable of sorting everything out (while also probably cursing me for how needlessly complex I've made turning on a light switch).
