When I got the first generation of Wyze’s Video doorbell I had to remove the wiring from the existing chime box as per the installation instructions.
It looks like with the Duo doorbell, you can use the existing chime box. So I could plug the cable I unplugged years ago (I hope I took a picture of it) and it should work normally, even for the 2 chime boxes (upstairs and downstairs) I had?
On a separate note, does Wyze Duo support 2 Wyze Chimes (I’m talking about the Chime included with Wyze Duo). I’m having trouble hearing it from upstairs, which is the reason I wanted to hook it up to the existing Chime box as well.
If you’re talking about something like a mechanical chime box in the home (probably with FRONT and TRANS terminals or FRONT, TRANS, and REAR terminals), then it should be possible to get your Duo Cam Doorbell to ring that if properly wired to power and if a Chime Controller is installed. The current problem is that Wyze Chime Controller is not available for separate purchase (though hopefully that will be remedied in the near future).
It is possible to wire your chime without Chime Controller, but many users who have done that have reported humming, buzzing, and/or phantom chime sounds (i.e., the doorbell ringing when it shouldn’t and when no one has pressed the button), so it’s not something I would advise.
Something else to consider since you mentioned two chime boxes:
That’s a discussion that includes posts from someone adding a relay into the setup in order to power 3 chime boxes with Video Doorbell v2. I don’t know if that would be useful to you or not, but there it is.
Regardless of whether or not you still have a picture of your original chime box (pre-installation of the original Video Doorbell), an inexpensive multimeter should be able to help you determine which wire goes where inside the chime box. That’s what I used to resolve a wiring issue with my own Video Doorbell v2.
