New 2 Camera Door Bell as "add-on" only device

It appears the new 2 camera doorbell is only available with a Smarthub.

Would like the product to be available as an “add-on” product only, like there is for other eufy doorbells… I have an existing Eufy Smart Hub with cameras/motion detectors and key pads connected already… I dont need another hub, but I would like the 2 camera door bell.
