The RollScout is a smart toilet roll holder that uses an infrared emitter and sensor to detect when the roll empties in order to alert the user to refill it by using a round amber light or a smartphone app notification. It is battery-powered and can run for up to a year on a single A23, since it only checks up the roll every few minutes for a split second. It was launched as a Kickstarter campaign with the price tag of $59 for the Pure Black or $149 for the 14K gold plated holder, but failed to raise its pledged goal of $37,500. The RollScout has been criticized as one of the most "useless" Internet of Things products.

In similar way, Kimberly-Clark Professional's Intelligent Restroom app collects data and alerts from sensors integrated into restroom amenities, from soap dispensers to air fresheners, as well as non-amenities like entrance doors.
