#676: Dooringer

When someone comes to my door late at night they may find themselves ringing the bell and waking everyone in the house.

Today’s invention is a doorbell which works out if the time of their arrival is after bedtime and if so, pressing the bell makes a call to my mobile phone (which would automatically set itself to discreet ‘buzz’ mode at my regular bedtime).

Different patterns of bell pressing (indicated on a small sign on the door), could call different individuals’ phones…without saying to the putative visitor anything about who is in or out, or supplying them directly with any resident’s mobile number.
