Existing chime trouble

Hi, I have tried to connect the Ring 2 doorbell to my existing chime. With the diode it either chimes constant, or not at all when I switch the cables around. Without diode it is not chimlng at all regardless how the wires are connected.

Hey @SteffenP! The best first thing to check here would be our Chime Compatibility List, to ensure your chime kit is able to operate with the Video Doorbell 2. If you have a mechanical chime kit, you will not need to use a diode. I hope this helps! :slight_smile:
