Nice one thanks for the feedback.
Have you seen my Bee In The Hive Sensor
? It will do what you are asking. To find out more about it and how to do it click here. You would use this sensor in a group with your motion sensor and add it into Motion Sensor - Binary Sensors input.
I have a look at that and add it to my list. Thanks for the suggestion. Just a question what if there are a lot of items in the area? It will turn ON and OFF everything
