Not sure about the stone...could you attach the button to the door, and choose an appropriate location for the speaker unit where it can receive the signal...try moving it around the house. our Honeywell doorbell is perfect and we have a second button. The signals have to travel through either 2 or 4 walls, assuming the signs go in straight lines (vs bouncing off stuff). If it does go in straight lines then the "4 wall" signal also has to pass through 2 layers of ceramic wall tiles. Anyways it works great!
