Correction: ABC News has amended and editor’s note to its story clarifying that the Bernalillo County Sheriff’s Department did not specify the type of smart device that called them to the home. An earlier version of this post cited ABC’s story and claimed a Google Home called police.

They were house sitting. It's not a stretch to think that homeowners had other smart devices to listen in and see what's going on remotely, and call police if necessary. Nest cam possibly? It works with Google Home.

Also, there was a daughter (no mention of age) who may have been able to trigger an alarm system or call herself (though a traditional call negates the "smart device" claim by the sheriff's department).

I'm concerned if smart devices will start intervening with human arguments. When they're necessary, it's indeed a lifesaver. When they're not it can really break up otherwise healthy homes and cause a lot of stress.
