Most of which you don't need IMO. When a bunch of stuff had to be redone after a kitchen fire, I told my electrician that I wanted everything to be dumb.
Apparently a short circuit in the control panel in the middle of the night. At least that's what the investigator said. I wasn't using it and was asleep. So I didn't start it. Was spontaneous. Didn't seem to be related to any external wiring.
