Hi @user55034. You want to make sure your chime is compatible with the Pro 2. If it is compatible, verify that you have installed your Pro 2 correctly using this Help Center page. You also want to make sure your transformer meets the requirements of 16–24 VAC, 30–40 VA max, and 50/60 Hz. If you have done these steps and are still having the same concern, give our support team a call for further assistance.
Thank you! I got the install sorted. I think I was installing the pro power kit onto the step down transformer in the garage. Instead, I installed directly on the doorbell chime inside the house as I was able to see the front and trans terminal screws.
