You are talking about mechanical devices, none of which are internal to the router, so who cares?
I say again, IP controlled strips are common in the IT world to reset "junk" switch equipment from cheap Chinese junk companies like HP, Cisco, Dell, etc. maybe we should have them remove the word "enterprise class" from their description?
And sometimes it's not the router. I've had more defective modems than routers and they seem to choke trying to get an IP assignment from the host modem/swx. Either way a reset needs to happen and he ain't home.
This is common practice and it works
