Hi, I have just bought the Nest Doorbell Battery.
I am wanting to use my various Google speakers and hubs to act as indoor chimes, I have followed the previous threads by making sure all of my devices are not set to do not disturb or quiet time but the indoor chime section is still greyed out and will not let me select it.
The "Indoor chime" setting for your doorbell turns your indoor physical chime off and on, but is disabled if your Google Nest Doorbell (Battery) is NOT wired (because there is no wired connection to your indoor chime).
Visitor announcements to your Google Nest speakers is controlled by the "Visitor announcements" setting for your doorbell: https://support.google.com/googlenest/answer/7672451?hl=en
