Your router is a point of failure, so an internet outage making it go weird doesn't mean you want all your stuff becoming on manageable).
IoT is honestly one of the best ways to rapidly learn SRE concepts.
Static IP addressing at this level is a curse.
On a home network with dynamic addresses: No need to worry about IP addresses; no overlaps happen, no mistakes, no spreadsheet table to manage. Use names (as long as DHCP works, then so does DNS). Renumbering the network is simple when that's useful.
It still works when the internet is down. And when the router itself breaks, we fix it or replace it and things work again. It's good to have a functional spare.

On a home network with static addresses: Micromanage IP addresses, keep a spreadsheet table, potentially make mistakes. Avoid using names (DHCP may be eliminated but DNS is still a failure point), making things harder to remember six months from now. Renumbering is arduous.
It still works when the router is down, but: When the router breaks, we still fix or replace it anyway. It's good to have a functional spare.

In terms of SRE: I don't need 5 9's of reliability for my smart light bulbs' IoT controls at home. They all still have some manner of physical switch, and they all can still be toggled on and off the old-fashioned way. Parallel controls work well-enough.
Everyone will get by almost-normally while I fix the router, which is a task that I'll set forth to be doing anyway for all of the reasons that household internet access provides.
