And they would like look a six-pack of fugly cheap plastic thingies. And you have to chain them up yourself. And they wouldn't talk to an integrated app. 300 buckadingdongs for 6 sensors, a hub and an app seems quite reasonable to me. This would be especially useful for a landlord to unobtrusively monitor properties.
