Hi @librachrm. To clarify, does the Doorbell Pro itself not ring the first time it is pressed? It should ring the first time it is pressed, and the internal chime should ring a few seconds after that as well. If you have a video of what’s happening, I can gladly take a look. When attaching this video, you will need to compress the MP4 file into a ZIP file, as ZIP files can be attached to your reply and not MP4s. In addition, you can upload this video elsewhere, such as YouTube, and then share the link to the video in your reply.
