Don't forget a smoke detector.
Either connected to an external siren or wireless link to another unit in the house. Battery ones are good these days.
Better still, a proper hard wired one (back to it's own fuse in the breaker) as you're wiring the place properly.
Being away from the house, God forbid there is a fire, you want to know before you look outside in the morning and see a pile of ashes!!
(PS: make sure you press that little test button regularly too.)
