Movie I remember is about a programmer guy who created this house, completely automated who made food, turned in water for all the house, talked with a woman's voice and practically had a personality of her own.
The guy was with his family in the house, if I remember well he had his wife, a son and a daughter, both older than about 14. There might have been a third son who was younger, but I can't recall.
Thing is, the father really loved his creation, and talked to her almost everyday, leading to a bit of his wife's jealousy. The house started returning to his feelings, and sensed the mother's anger over her. The house had cameras all around, so she started watching everyone and started to try killing them for her to be alone with the father I think.
The scene I recall the most of this movie is when a guy who seemed to be interested in the family's daughter, invades the house at night and is attacked by a type of food cart robot, who pulls a knife and kills him with it. That same guy showed up to the family as a seemingly friendly neighbor.
There is also a scene related to the showers not working, and I can't remember how the film ends. The movie must not be older than 1990, and I must have watched between 2000 and 2003 on television.
Another thing that might help, the son was blond and the daughter had short black hair. The father looked a bit like Robert Carlyle or John Glover. That's about all I can remember.
I really want to find this movie because for me it was a great reference of house automation technology, besides being really thrilling and interesting.
EDIT: A few specific scenes I remember:
The mother in a kind of white kitchen, ordering the house (which I think is called by a woman's name) to bake something in the oven I guess, and she automatically opens the fridge.
The son of the family orders some milk or similar liquid to the house in the same kitchen from above, which mecanically offers it to him. Later on the house spies on him sleeping on one of the cameras.
The father is seen on a laptop, where there are some program code lines, and talks to the computer woman/house.
Some family members are seen carrying some chopped wood on the back of a pickup truck, in the yard outside the house. In this scene I remember the daughter and the guy who is killed by the food cart knife. I think the father also appears. The place around was pretty rural I believe.
EDIT 2: The movie is a LOT similar to Homewrecker (1992). I am frustrated as how much it fits into the one I have seen. The house doesn't have mechanical arms like in this one, and if there is a child on the movie (which I think unlikely), it barely appears. The movie I'm looking for seems to be somehow more recent in appearance than this one. I might be wrong though.
