No, you cannot add multiple chimes.
Wyze Video Doorbell Pro comes with one Wyze Chime Pro that's pre-paired. You can not purchase individual chime devices, and the doorbell doesn't pair with more than one chime at a time.
Important: A Wyze Chime Pro is required to use a Wyze Video Doorbell Pro, as it provides the connection to your Wi-Fi network. Even if you use your mechanical doorbell chime, you must use the included Wyze Chime Pro as well.
