Here’s my no wiring required version:
I taped a smartsence multi to my ding plate inside my doorbell. The accelerometer inside detects the vibration from the ding plate being struck by the doorbell being rung. No fuss, no muss, no wires 
For notifications there’s [Notify Me When… App with Button functionality][1]
To turn my patio light on there’s [Lights On,On Vibration.groovy][2]
