It doesn’t appear to be available separately at this time. This is discussed in the official announcement topic for Duo Cam Doorbell. (I think much can be learned by reading that topic.) Whether or not you contact Support is your choice, though I’m skeptical that it would give you a better answer. Maybe asking them about it would put it on Wyze’s radar, though, so it’s not a bad idea. I personally think the Video Doorbell v2 Chime Controller and the new Wi-Fi Chime should be made available as accessory purchases.
Yes, I’ve read those here in the Forum for Video Doorbell v2, and now I’m also seeing at least one report of successfull Duo Cam Doorbell use without the Chime Controller:
If we’re talking about the same thing, then my understanding of the component that ships with the original Video Doorbell is that it’s a fuse wire that’s intended for use in bypassing the home’s built-in chime, taking the chime completely out of the loop and providing some protection from power surges to the doorbell, so I wouldn’t expect that to work for Video Doorbell v2 or Duo Cam Doorbell if wired in the way that Wyze advises for the original Video Doorbell installation; however, I suspect that it could still be useful if someone wanted to wire one of these newer doorbell models without the Video Doorbell v2’s Chime Controller. This is what I might be inclined to try if I had one of those parts on hand:
- Turn off power to the transformer.
- Connect one end of the original Video Doorbell’s fuse/jumper wire to the built-in chime’s FRONT terminal.
- Use a wire nut to connect the other end of the original Video Doorbell’s fuse/jumper wire to the wire coming into the chime box from the doorbell button’s location.
- Restore power to the transformer and test.
Caveats:
- I am not an electrician.
- I don’t have a fuse wire on hand (I’ve never owned the original Video Doorbell), so I have no idea what its rating/specifications are.
- I’m imagining any one attempting this would have already removed the Video Doorbell v2 Chime Controller from the chime box (what I picture your likely scenario would be), so at that point the only wire attached to a chime terminal would be the wire coming from the transformer and already attached to TRANS, and the disconnected wire at the starting point would be from the doorbell button location.
I don’t know if something like that would be useful or not, but on its face it seems like it would have the potential to provide some protection to the doorbell camera unit by inserting a fuse into the circuit. I don’t know why it wouldn’t work.
