That page makes it seem like only the Thermostat has Farsight. You mention smoke alarms. I do know that my Nest Protects (smoke alarms) have motion detection though. Very handy nightlight in the middle of the night. Though if tied into the sole source of an alarm system I know it'd be a problem because my dogs can activate the nightlights in the Protects. Pets really make home security hard, I'd bet.
