I built what is basically a smart plug, but it uses 4G connectivity instead of my standard WiFi. The idea is that if my home network screws up and I need to reboot my router and modem, I can still do that remotely. There have been 2 times in my life that I really wished I had this set up because my Plex server was down while I was traveling. The ideal scenario is that I never have to use the thing, but whenever I see this flashlight post, it reminds me that I kinda do want to need it just once.
