Problems fall into two broad areas:

1) compared to my phone or my car, my house is not very smart, so forgetfulness on my part (not locking a door or turning off an oven) can be a problem - particularly when I'm away for a day or a week.

2) it's a complex place and it takes a village to keep it running and properly maintained. It would be great to have the equivalent of a building superintendent that could very regularly check to make sure everything is working and up do date and get things done as needed (painting, gardening, sprinkler repair, lightbulb changes, etc.)
