Is anybody doing anything clever with a variable for WHO was last in the house?
Use case 1: my wife left the door unlocked today. I left the house at 07:00, she left at 09:00 and the verandah door was left unlocked. I got the message from HA saying the doors had been left unlocked but it would be handy to have sent that to her, so she could have quickly popped back to remedy.
