Not if it looks great!

I just bought a house and discovered that it has a working long-tube door chime system! It’s got 3 brass tubes, each over a meter long, perfectly tuned and plays a short musical number when someone presses the button. You can sure hear it anywhere in the house, but I really like this MQTT idea!
