@Bashy, thanks for the response. Not sure why it isn’t available for any DB given they all connect to the network in order to get to the web. So it should not be too difficult to make them talk together over LAN/WiFi when internet is down but local network is available.
Chime and Chime Pro, minimally, should be able to interact with other ring products over local network as there is no driving reason for cloud access with those products.
Ring products are expensive bricks when there is no internet, which is problematic and unnecessary.
