Sure. All that stuff has consequences. I also used to run a DNS Adblocker on that machine. So after a power outage, all the lights in the kitchen and livingroom (those are the smart ones) would turn on at full brighness (their default state). The internet wouldn't ever come back since it's missing its DNS server. Obviously I can't get any notification of the incident, since my server is down... And I fall back to being reachable via phone or SMS. If my wife tells me via chat or email... That's down, too.

I'm still working on a better solution. It ain't easy, though. It's certainly easier to use some cloud services and have other people keep the infrastructure running in some datacenters which have more redundancy... We have light switches, though. All my smart home stuff is just retrofitted. So we can still turn it off or on with the wall switches. I won't change that until I come up with a solution to this problem.

And it's just some lights and the washing machine. While I am a nerd and tinkerer, I don't any reason to own a smart toaster, fridge or Alexa. YMMV, of course.
